The rooftop battle dragged on for over half an hour before it finally ended.
By the time it was done, Susan couldn't even stand.
Ryuuto—still full of energy as ever—carried her back to her room. The moment she hit the bed, she was out cold. He, on the other hand, was wide awake. Physically speaking, he could probably handle a few more girls without breaking a sweat… though he wasn't about to test that theory right now.
As he lay there, a thought struck him.
"Oh yeah… when I beat Thor earlier, didn't I get a system packet I never opened?"
[Ding! Item Detected — "Senju Tsunade Data Pack"!
Open now?]
Ryuuto grinned.
"Tsunade, huh? Oh, this might be good."
After all, in the world of shinobi, Tsunade wasn't just a healer—she was the healer. Strong, terrifyingly beautiful, and capable of cracking mountains with her bare fists.
"Hell yeah, open it."
[Opening…]
[Abilities Unlocked:]
Monster Strength Technique
Heavenly Body Control

Chakra Scalpel

Summoning Jutsu: Slug
Mitotic Regeneration
Hundred Healings Mark
Ryuuto's eyes gleamed. "Damn… jackpot."
Now he could heal almost any injury—his or anyone else's. If he got injured mid-fight, he'd just slap on a jutsu and walk it off like nothing happened.
"This system's finally being nice to me for once," he muttered. "Tsunade's packet today, maybe Madara's or Kaguya's next? That'd be insane."
He cracked his knuckles, grinning at the thought. Sleep? Forget it.
He slid out of bed carefully so he wouldn't wake Susan, then stepped into the moonlit backyard. Stretching his shoulders, he let chakra flow down his right arm—slow, focused.
"Alright, let's see if this 'Monster Strength' thing really lives up to its name."
He slammed his fist into the ground.
Nothing.
"…huh?"
He blinked, then frowned. Maybe he'd used too little chakra.
The next second, the earth rumbled like something huge shifting beneath it. Five jagged cracks exploded outward from where he stood, crawling across the ground like living snakes.
"Whoa…"
The backyard tilted slightly under his feet. A few tons of packed dirt slid away from the impact zone.
"Okay. Yeah. Definitely not fake," Ryuuto muttered, stepping back to admire his handiwork. "Guess that's one way to ruin a lawn."
He rubbed his chin. "So, if I focused chakra into my forehead, would that count as… Iron Head Technique?"
He glanced at a nearby wall.
"…nah. Messing up my hair isn't worth it."
To test further, Ryuuto summoned the Dark Spear and pricked his arm, watching blood bead up. Then, forming a seal with one hand, he called out:
"Summoning Jutsu—Katsuyu!"
A ripple of energy spread through the air. Moments later, a massive slug thudded onto the cracked earth. Her body shimmered blue-white under the moonlight, soft and round like a giant marshmallow with antennae.
She blinked down at him. "Who are you?"
"I'm the one who summoned you."
"Impossible. My contract is with Lady Tsunade."
"It was. Now it's with me."
"That cannot be," Katsuyu replied calmly. "As long as my bond with Tsunade exists, you should not be able to summon me."
Ryuuto folded his arms. "Well, the system says otherwise. So, yeah, guess I'm your master now. Anyway, show me your healing jutsu."
Katsuyu tilted her head. "You are injured?"
He raised his arm. "A little scratch."
Katsuyu lowered her face and pressed her chin gently against his wound. A faint, soothing warmth spread through his arm. In ten seconds, the cut vanished—no blood, no scar, no trace.
Ryuuto stared. "That's… actually insane."
He flexed his fingers, grinning wider. "Flawless regeneration. Even better than I expected. If Susan or Natasha ever get hurt, this'll save a lot of trouble—and keep them looking perfect. Katsuyu, you're a blessing."
The slug blinked. "Tsunade's techniques are meant for healing and protection. Use them wisely."
"Relax, I'm not planning on starting a hospital." Ryuuto smirked. "By the way, how many people can you heal at once?"
