"You..." Yusei looked at the graceful young woman in surprise, so shocked he was almost speechless.
The scene before him was so stunning that he didn't even notice the system's task completion notification.
Athena also slowly awakened from the transformation. She had become more mature.
Compared to her childhood cuteness, she now possessed more charm, beauty, and maturity. Every smile and glance carried an alluring appeal.
Clearly, Athena also noticed the changes in her body. She was initially surprised, but then she saw Yusei staring dumbfounded at her, and a slight curve appeared at the corner of her mouth.
Without a trace of shyness, Athena sat down beside Yusei just like that.
She brushed back her black hair, slightly lowered her head, and actively gave him a light peck.
"Mmm..."
After a long while, Athena released him, looking at Yusei with a smile.
"This one is now in her complete form."
Yusei had already snapped out of it earlier. He also knew about the system's mission completion prompt but hadn't claimed the reward immediately.
Now, hearing Athena's words, he couldn't help but raise an eyebrow and smile lightly.
"Goddess-sama, the initiative isn't determined by height, you know."
As he spoke, the room's lights suddenly went out.
…
The next day, the birds outside chirped noisily, making it impossible for Yusei to sleep. He slowly opened his eyes and immediately saw Athena lying beside him, looking at him with a faint smile.
Compared to the mature Athena from yesterday, she had reverted to her childlike form, but Yusei wasn't surprised.
He gave her a light peck on the lips, gently placed her to the side, and sat up.
"What would you like to eat? I'll cook for you myself."
"This one does not need to consume human food."
"Haha, just try the taste. Some things are really delicious."
Yusei smiled. Seeing that Athena also wanted to get up, he quickly pressed her down.
"You should rest. Even for a goddess, walking will probably hurt right now."
Hearing Yusei's words, Athena seemed to recall something, her face blushing, but she didn't try to get up again.
Instead, she obediently lay back under the covers, looking at Yusei with a faint smile.
Right now, she truly felt extremely happy. The wish she had pursued for countless years was finally coming true at this moment.
That's right, no matter how powerful strength was, it couldn't compare to someone who loved her. For the first time, she felt so fulfilled.
Although they hadn't known each other for long, Athena didn't have a human concept of time. What she cared about was mutual affection and whether they liked each other.
Without a doubt, they were mutually affectionate, and she liked him very much… it was the so-called 'love at first sight'.
Moreover, she had reclaimed her true form, so Athena now only saw a future filled with brightness.
After having Athena lie back down to rest, Yusei went to the kitchen to make breakfast.
Don't underestimate him.
In the past, at home, he was the one who handled the meals for Kanna and Shiro occasionally.
One could say he already had experience as a caretaker for children.
However, Yusei felt a bit emotional. Something happening with his god-servant was expected, but he hadn't anticipated it would be so soon.
If he had to count, his real first time should be with Athena, right?
Even with Asuna, that was inside a game, not physical, just the first time in terms of memory.
So his current relationships were quite messy.
Yuuki Asuna was his first girlfriend, so theoretically, she should be the main wife. And yet, Kaguya was his fiancée, so according to the engagement, Kaguya should be the main wife.
And now there was Athena, with whom he shared his first time. If based on that relationship, Athena would be the main wife.
So who was it ultimately? Although she was a god-servant, Yusei could feel Athena's feelings for him were genuine. Hadn't she said, 'Yusei is more important than power'?
He naturally treated Athena as one of his own as well.
He felt the matter of the main wife could be decided later. He would take it one step at a time. But for now, it seemed Athena was slightly ahead.
After making breakfast for Athena and ensuring she rested well, Yusei went to the underground training room. Last night, after Athena signed the contract, his task was completed.
Sharingan level increased by one.
Eternal Mangekyo upgraded by one level becomes the Rinnegan.
Thinking of the immense power of the Rinnegan, even Yusei, who had obtained Authorities, couldn't help but feel excited and thrilled.
Suppressing the excitement in his heart, Yusei silently chanted, 'Claim reward.'
As the mission's reward was distributed, Yusei immediately felt a warm current in his eyes, a tingling, slightly stinging and itchy sensation.
Yusei resisted the urge to move his eyes, feeling the increase in his Ocular Power. Only when the changes completely stabilized did he open his eyes.
When he opened his eyes again, Yusei immediately sensed he had gained a series of new abilities.
The Rinnegan was the Sage's Eye that controlled life and death, possessing the power of the Six Paths.
After this power manifested in his body, the first thing Yusei did was spread his hands towards a large boulder in the distance.
"Bansho Ten'in!"
A powerful gravitational force directly lifted the large boulder in the training room, sending it flying quickly towards Yusei's hand. Just before it reached him, Yusei abruptly switched powers.
"Shinra Tensei!"
The boulder was instantly repelled by an intangible force, but it didn't crumble into powder under the squeezing of the two forces as Yusei had imagined.
"Can't use Bansho Ten'in and Shinra Tensei simultaneously? Maybe I can once my proficiency increases."
Yusei looked at his hands, his heart filled with excitement.
Soon, he left the training room. Next, he needed to go outside to test the limits of his current power.
Simply put, the limits of Bansho Ten'in and Shinra Tensei.
After experimenting in the forest all morning, Yusei, panting heavily, finally had a rough estimate.
First, Shinra Tensei: Yusei couldn't reach the level of the original Pain's full-power blast that destroyed Konoha.
But if he used Shinra Tensei at full power now, he could only repel everything within a one-kilometer radius.
As for the strength of Bansho Ten'in, Yusei felt it mainly depended on the level of Chibaku Tensei.
Having just obtained the Rinnegan, Yusei's Chibaku Tensei wasn't very strong yet. He could probably only create a 'small moon' with a diameter of about a thousand meters...
