The next morning, she received a letter from Kakashi—the first in weeks. She smiled as she read the good news about her friends, the ANBU colleagues he trained with every Tuesday, the hospital...
"I took a while gathering the information, but I hope it makes you happy to know your friends are doing well. They still meet up on Mondays when they can, though they have more missions outside the village now. Understandable, considering they're all chunins. Karin is working full-time on the barrier team. She says she's found her calling, but she hopes to be promoted to chunin in July. Interestingly, she's become close friends with Shino. I've seen them together a couple of times, alone, in the village. I foresee a potential romance between them."
Seina smiled imagining outgoing Karin with Shino, who was the most antisocial of them all. Had her cousin been intrigued by Shino's kikaichu due to her sensory skills? Or maybe it was his opposite personality that attracted her? Whatever the reason, she was glad they were friends without Naruto or her needing to play middleman.
"I also found out that Shikamaru is preparing for next year's jonin exams with Neji—at least that's what his father says. And you won't believe it… Asuma and Kurenai have started dating. It was expected, but I thought they'd take a bit longer to confess. In the end, Asuma was too jealous to wait (maybe I had something to do with it by giving Kurenai Naruto's movie tickets to go with Genma…). Honestly, I'm happy for them. They make a good couple.
I'm a bit jealous, to be honest. I wish you were here, even though I know how dangerous it is with Danzo still active. Every time I see a couple or feel the weight of my ring, I can't help but think of you. I miss you so much that sometimes I don't even know how to keep going. Sometimes it's hard to go back home knowing you won't be there."
Seina sighed as she read Kakashi's sorrow written in those white sheets. She could sense how, in the few letters he could send her, Kakashi was growing more melancholic. She could read in his words how he seemed to be distancing himself again from home or from his friends, even though he'd been spying on them from afar to answer her questions. That was the last thing she wanted. She didn't want him to slip back into that mindset he had while in ANBU before returning to jonin duty and becoming her teacher.
The only thing she could do to help was write him more letters—so that's what she would do. She placed Kakashi's letter into her secret chest, where she kept all her correspondence, and sighed. There was no point in sending a reply now, knowing he'd already left the village on another mission.
Someone knocked on her door. It was Sasuke, holding a letter.
"Your weekly letter?" she asked rhetorically.
"Yeah."
It was the last letter of June, and there was still no sign of Itachi. That very morning they'd settled in a new spot within the Land of Fire—this time closer to the Land of Rivers than ever before. She could sense Itachi's presence westward for weeks now, but it never seemed to move closer. In fact, since they started placing themselves near his coordinates, he hadn't once moved in their direction. As if their presence alone repelled him.
Seina sent the letter with her dove. She didn't feel like writing to Itachi now, knowing she'd already decided they would go after him when the deadline arrived. It wasn't something they had told Sasuke, and certainly not Jiraiya, but she could already imagine how that conversation would go:
"No, no, no, and no. I said no," Jiraiya would say. "We're running from Akatsuki and you want to head straight toward Akatsuki. Are you crazy? Don't answer that."
"But, ero-sennin! We made a promise to Sasuke!"
"I don't care, airhead! That'll teach you not to make promises so recklessly!"
She stifled a laugh. Watching the dove fly off, she yawned and returned to her fuinjutsu scrolls. At the rate she was devouring them—with the help of her clones too—she'd soon run out of material to study. It was fascinating how differently the Uzumaki treated fuinjutsu compared to Jiraiya. Her father, described as a fuinjutsu genius despite not being an Uzumaki, was on par with her mother, who had learned fuinjutsu until the age of nine before leaving Uzushiogakure and later becoming Mito Uzumaki's apprentice. Once she realized that, she knew her father's genius was largely thanks to his wife—who had no doubt taught him a thing or two during their courtship.
"Can we train a bit? I want to get some air," Kurama said in a bored voice.
"Sure."
She sat on the grass under the warm summer sun and opened the seal Jiraiya had modified. Kurama stretched figuratively within her, breathing in the late-June air deeply.
"Seina-nee?" Naruto asked. "Can you heal my arm real quick?"
They opened their eyes to look at their brother. Kurama and Seina, joined in one body, saw how Naruto had been trying to launch his rasenshuriken again—that's what he called it now. He was close to mastering it, but still couldn't isolate the wind chakra nature from his arm.
"Ah, Kurama."
"We'll need to give you two a name when you're in that form," said Sasuke, walking out of the tent with some weights in hand.
"I know! How about Seiku?"
"Seiku?" she repeated out loud. "Sounds like an ice cream brand."
"Seima?"
"…"
"What about Seirama?" Sasuke suggested. "Seima is basically your name with an 'm'."
Seina held back a laugh at the ridiculous names they were suggesting. Seima was awful—she almost preferred the ice cream name. As for Seirama… it reminded her of Tobirama, the Second Hokage.
"Please, when you guys have kids one day, think about their adult lives before naming them."
"Hey!" Sasuke and Naruto shouted in unison. She dodged a rock that nearly hit her forehead.
"If I had to choose one, I'd go with Seirama."
"Then Seirama it is."
"Makes me want to stay hidden just to avoid hearing that garbage name."
She stifled a laugh at Kurama's irritated thought. They trained for a while using the chains. Partially transformed, they had nearly unlimited power—but even Kurama needed training. That's how Jiraiya found them later that evening.
"Still training? Good work on those five chains, by the way. You've mastered them perfectly."
"Thanks. It's easier to avoid mistakes when we train together first."
"You'll have to train again once Kurama has his own body. You know that, right?"
"Of course," she rolled her eyes.
"And fighting with a bijuu doesn't make you invincible. They're not limitless sources of chakra, no matter what people think."
"I know. Though, in what scenario could Kurama ever run out of chakra?"
"Who knows," the pervert shuddered. "Best not to think about it."
"I can recover chakra quickly by using senjutsu," Kurama chimed in, having followed the conversation. "The problem is, I have to stay still to gather sen chakra and convert it into my regular chakra."
"Really? I didn't know that."
"It's the same thing the pervert does with the toads on his shoulders, haven't you noticed? That's why he partially transforms—his summons collect sen chakra for him, letting him stay mobile and keep fighting while increasing his reserves."
"Couldn't we try something like that too? You could take the toads' role while we're connected through the chains."
"We could try, but it would be more efficient if I used my own skills too. Especially if we're talking about a fight where I, someone with massive chakra reserves, have run out… If we're in that situation, we're screwed."
Seina shivered. He was right. Then she had an epiphany. If Kurama couldn't stay still to gather more chakra… why not gather it ahead of time? Wasn't that what she was doing with the seal on her forehead? Why couldn't Kurama do the same?
"Huh. That never occurred to me. There's one problem though..."
"What is it?"
"I'm not human. I can be sealed, but I can't have seals placed on me."
"Well, there goes that idea," she sighed, defeated.
"Not so fast. It was a good idea. Just because I can't have a seal like that placed directly on me doesn't mean I can't have access to one filled with chakra that I can use."
"...You mean... putting it on me?" she asked, slightly confused and a little excited.
"Exactly. We need to create a seal like the one on your forehead, but with unlimited capacity and no healing properties. It would just be like an external battery—the kind you used in your old world. That would let me constantly supply you with chakra, and if I somehow ran out of chakra during a fight, I'd have access to my own chakra stored inside your seal."
"We're geniuses."
"I know. Go talk to the perv and draw up a few designs. I want to start filling it with chakra as soon as possible."
Seina stood up with growing excitement. Jiraiya, however, didn't seem nearly as thrilled.
"Face it, ero-sennin, I'm going to do it with or without you. It'll take me longer to test the seals without your help, but I'll figure it out eventually."
Jiraiya muttered something under his breath she couldn't catch, then threw his hands in the air.
"Fine! You're just as stubborn as your mother."
"Thanks."
"That's not a compliment!"
"It is," Seina grinned as Jiraiya shot her an exasperated look.
"You're lucky. My informant won't show up for another thirteen days, so we can start now. Let's see what you've got in mind."
Seina conjured a scroll to show him the model she had in mind. It took five days and over twenty versions to finally convince him that one of them might actually work. It was based on the seal on her forehead, but modified. Jiraiya examined it for hours, checking for errors. Honestly, aside from trying it, there wasn't much more they could do.
"Are you sure?"
"Yes," she drawled, clearly tired of repeating herself.
"Alright. Take off your shirt. I'll remove the metal armour."
She did as told, lying face down on the grass. He was going to place the seal on her back, between her shoulder blades. It was the size of a coin and shaped like a compact heptagram—a seven-pointed star. When he applied it, she felt a burning sensation and a deep, overwhelming emptiness.
"Are you okay?"
"Yeah."
"What do you feel?"
"Empty," she replied, sitting up on the grass.
"Not surprising. This seal could theoretically hold an unlimited amount of chakra. Let's have Kurama try transferring chakra into it."
Kurama did so, linking a projection of his chakra to her new seal. She shivered as she felt the demonic chakra flow through her. It was like a mini electrocution—strange and tingly at the same time.
"Does it work?"
"It works," she grinned from ear to ear.
"Your first original creation from almost scratch!" Jiraiya smiled, ruffling her hair.
Seina couldn't stop smiling. Unlike her forehead seal, which became visible when full, she'd designed the heptagram to change colour based on how much chakra it held. It would start black, and once it reached the same amount of chakra as Kurama, it would turn bright scarlet. Getting to that point would take months, maybe longer, depending on how much chakra he transferred each time.
"I'll try giving you a tenth of my chakra every day while you sleep. The seal supposedly has no limit, so in ten days it should hold the full amount of chakra I have right now."
"Which means that if you keep filling it for a whole year, you'd have… what, thirty-six times your normal chakra?"
"Exactly... Which means I could run out of chakra thirty-six times in a single fight."
Seina shivered as she realized what they had just accomplished. They had managed to push Kurama, the most powerful of all the bijuu, beyond his limits. She could feel the thread of chakra continuing to fill the seal, though it was only a millionth of Kurama's chakra.
"I'll gradually give you more chakra, in case it turns out to be painful."
"Great."
That night, however, after taking a shower and putting on her pyjamas, when she lay down in bed to check whether so much chakra might be painful or have negative effects, she didn't expect what would happen. The thread of chakra that had been permanently connected to her began to increase in volume little by little. At first, she only felt a tingling sensation all over her body, starting from her back, but then a warm feeling began to spread through her, like she was soaking in a bath.
"I didn't expect this," Kurama murmured, oddly curious, as he sensed how she welcomed the comfort of his chakra.
It was different from when Kurama lent her chakra in battle. Now, it felt like a blanket, though instead of wrapping around her like during training, that comfort was inside her. She mentally gave thanks that the rooms were soundproofed, because she couldn't hold back the wild laughter that wanted to burst out—euphoric from the power she was feeling—when Kurama increased the chakra flow, giving her everything he had until it bordered on painful, making her cry out briefly. He slowed down once they both realized it was too much.
"I can't give you a full tenth of myself, but you're handling a little less pretty well."
Seina was too dazed to respond with words. She didn't need to—after all, they were one and the same. She didn't know why, but she suddenly thought of Kakashi. Maybe because this sensation felt the closest to one of his embraces, even though it had been months since they last saw each other. This time, the memory of Kakashi wasn't stained by sadness or melancholy, and so she fell asleep with a smile on her face.
"Take off your clothes, Seina," she heard the whisper in her ear. It was Kakashi.
She took it off with a thought. Her magic vanished the clothes to the floor and she was completely naked on top of the sheets. She moaned again when she felt Kakashi's presence enveloping her, and a hand trailing down her torso, and further down... Seina stroked her stomach, following the electric trail of that male hand, firm and warm, until she had it between her fingers. She spread her legs, leaving herself completely uncovered. She was so wet he could slip a couple of fingers inside her with no problem. She grabbed one breast, pinching her nipple, as she spread her legs wide to let those confident, expert fingers pleasure her.
"I want to see you cum as I penetrate you."
She convulsed as she imagined Kakashi's fantasy as her own. She saw him, naked with his muscles tense with anticipation and his body slightly pearly with sweat as he held back the urge to take her right there, while he stared with his disparate eyes as his own fingers opened her pussy again and again, before he licked his lips at what he was planning to do. She closed her eyes and imagined a Kakashi clone penetrating her while the real Kakashi watched with greedy eyes, knowing they were both horny because he watched them fucking. Opening her eyes she saw him masturbating at the foot of the bed slowly, his muscles contracting from the effort while his other hand continued to play with her.
She came, convulsing, with Kakashi's fingers inside her, and his lips resting on her thighs, tongue kissing her everywhere but where she wanted to be kissed the most.
"Again," she moaned.
"Get on all fours, my Seina," Kakashi purred, licking her navel with his tongue, bristling her skin.
Seina obeyed. She leaned her torso on her bed and let her hips in the air, spreading her legs. If someone could have come through the door they would have seen everything. Kakashi caressed her again with his hands, running his hands all over her body, while she moaned and cried with pleasure.
"I want you in my mouth."
Kakashi didn't listen to her. He suddenly penetrated her in a rough way. Seina closed her eyes, stifling a squeal of pleasure, feeling his hand also roaming her torso, her breast, toying with her nipples. She cried out as she felt a more powerful thrust than usual and at that precise moment an arm turned her head and a tongue invaded her mouth, stifling her squeal.
She snapped her eyes open, seeing her dark room. As expected, Kakashi had been a dream. An illusion of his imagination. And yet... she had felt him warm and hard against her back, inside her. She was going crazy. She'd conjured a toy without even thinking about it. She had woken up on the edge of the abyss, totally wet, so it didn't take her long to cum for the first time.
She gazed at her body glistening with sweat and glistening with arousal. She rose from her sheets to use the dildo in a sitting position. When it filled her completely, she lifted her hips slowly, then slammed down, impaling herself with her toy if she was Kakashi. She touched her breasts, squeezing her nipples, as she increased the rhythm. She bounced her body as she fantasized about doing with her fiancé more than once, pleasuring herself.
She moaned, leaning back on the bed and resting her hands on the sheets so she could give herself more thrust. It didn't take long before she was coming again, screaming in pleasure and imagining again Kakashi's grunts in her dream. She stretched out on the bed after making the toy disappear.
The next morning she woke up naked, still a little wet. She looked down, seeing the stained and wrinkled sheets. She was a real mess. She had to take another thorough shower and remove all evidence of what had happened.
What she couldn't get out of her mind was her fantasy of Kakashi. She wanted to see him. That gave her an idea. One that could perhaps restore some of his spirits.
"What are you planning now?"
"I plan to tell him my fantasy. He's sad now, so..."
"You'd rather make him horny than sad? It might work. No way I'm missing this."
Kurama stayed while she sat down to write an erotic letter to Kakashi. Seina had to bite her tongue and avoid thinking about last night or she would end up having a morning session with her hand again. She heard the laughing sound of her inner demon.
"Dear Kakashi,
I couldn't get over the fact that you're distancing yourself from everyone but me again. Sometimes even from me. I was thinking about how to help you, but I've finally figured out how to do it. Shock therapy. I hope you are alone when you read this letter.
Remember our last night alone together? Well, let me tell you that it served to fuel some of my fantasies. Just yesterday I had a dream about you. I dreamt that you were here with me and that... Well, I don't know if I'll be able to write what you did to me without getting wet again.
It doesn't matter. I'll tell you. I dreamt that you penetrated me with your fingers, that you licked my thighs and kissed my stomach while you stared at me as I came. I dreamt that you put me on all fours to penetrate me from behind. But you know what disappointed me? That in my fantasy you didn't watch as your clone fucked me while you slowly masturbated and then took his place.
You know the first thing I want to do when I get back to Konoha? I want to have a few days alone so you can fuck me over and over again. I want to kiss you properly, I want you to touch me, I want you to mark me, I want to scream your name, I want to kneel before you and have your cock in my mouth while you grab my hair and pinch my nipples. I want you to cum inside me.
I don't want you to be alone in ANBU again, so do whatever it takes to keep your sanity. Do you understand me? That's an order.
Seina."
