Main World.
Kamiyo Ai's house.
A flash of light.
Kamiyo Ai, who had been staying in the One Punch Man world, had returned home.
Although she could live at the shrine...
This place held precious memories.
So occasionally...
Kamiyo Ai also chose to come home.
But...
Having just finished hunting a few monsters, she was really tired.
Turning on the light, Kamiyo Ai leaned back on the sofa, her eyes somewhat dazed.
If only Master were here.
A quick magic replenishment would restore her.
Unconsciously, images appeared in her mind.
Just thinking about it made her ears burn.
After all, she hadn't thrown herself at him yet.
For Kamiyo Ai...
Even just replenishing magic was already a very exciting behavior.
Besides that...
Some of her fellow servants were proficient in recovery magic, even able to restore magic power.
However...
Feeling the heaviness in her body, Kamiyo Ai shook her head.
Forget it.
She didn't want to move.
She'd just wait for natural recovery.
She stood up, about to go to her room to sleep.
Thump, thump!
But just then, a knock sounded.
Who would be looking for me?
A flicker of confusion appeared in Kamiyo Ai's eyes.
Even her fellow servants rarely came here.
Sensing...
It was Ei?
She was a bit surprised, but since it was her own younger sister, she opened the door.
Creak—
Seeing her older sister, Kamiyo Ei was about to speak, but hesitated.
Why did her sister look so tired?
Was she disturbing her sister's rest by coming here?
But...
Her sister's clothes were a bit messy, as if she had been in a fight?
Her sister getting into a fight?
Normally, she couldn't even imagine it.
But...
Perhaps it was related to supernatural powers.
"Come in."
Kamiyo Ai opened the fridge. "No time to brew tea. Coke or juice?"
"Juice, please."
She took two cans of juice from the fridge and handed one to Kamiyo Ei.
Taking the juice, Kamiyo Ei opened it and took a small sip.
Sitting on the sofa, her eyes were hesitant.
Was it a bad time to talk to her sister about those things now?
But...
She had finally waited for her sister to come home.
If she missed this chance, she didn't know how long she would have to wait.
"Out with it. What's the matter?"
Kamiyo Ai sat down across from Kamiyo Ei, a hint of confusion in her eyes.
Although she had a good relationship with this sister...
This was the first time she had come so late.
Had something big happened?
Kamiyo Ei gripped the hem of her clothes, hesitated for a moment, then said:
"Actually, it's about Mr. Ayato."
Hearing this, Kamiyo Ai's expression darkened.
She said in a low voice, "Did that old bastard send you?"
"No, it's not like that."
Kamiyo Ei waved her hands repeatedly. "This was my own idea."
She knew very well how bad the relationship was between her sister and their grandfather.
"Sister, you have to believe me on this."
Kamiyo Ei hugged Kamiyo Ai's arm and shook it like she was acting coquettishly.
Kamiyo Ai humphed lightly, but her expression softened a lot.
"Even if that old bastard didn't send you, it probably has something to do with him."
"Fine. Ask your questions. If I can answer, I will."
After all, this was her only sister.
She still couldn't bring herself to turn her away.
"I knew you were the best, sister."
Kamiyo Ei beamed. "Sister, you've mastered supernatural powers, haven't you?"
"Yes."
Kamiyo Ai nodded.
"And it's all because of Mr. Ayato?"
"Yes."
Remembering this, a smile appeared on Kamiyo Ai's lips.
"Then, sister, can you tell me exactly how Mr. Ayato did it?"
Not just their grandfather...
Even Kamiyo Ei herself was extremely curious.
The family curse since ancient times...
That god had mysteriously disappeared.
And her own sister...
Had disappeared for such a long time.
She came back looking like she had been through a big battle.
Although she seemed very tired...
She could feel that her spirit was on a completely different level compared to before.
Hearing Kamiyo Ei's words, Kamiyo Ai fell silent.
Because of that old bastard...
She didn't feel like saying a single word.
But...
She glanced at her younger sister and sighed.
A beautiful girl.
She believed that even if she didn't say anything, she would eventually figure out what had happened.
It would just...
Take some time.
"I can tell you, but are you prepared to face the consequences of entering another world?"
"Yes, yes."
