"Aki, how many times do you know?"
(That's ... noisy. Ritsu-neesan ...)
Akihiko Narumiya, who has been pointed out for his untidy lifestyle, sighed many times in his heart.
Around the time he was tired of messing around, he happened to get an item that he bought online.
Akihiko rushes to the front door, interrupting Ritsuko's sermon, as if he was waiting for it.
If you go upstairs as it is
"What? What did you say to Ritsu-nee? Really, Aki is awkward."
"Uh, it's noisy. Doesn't it matter to your sister?"
"Why, people are worried and talking to me!"
This dynamic person is another sister, Makoto Narumiya.
This rough-minded older sister has been mercilessly scooping out her trauma when she has been talking about things for a long time.
Akihiko ignores her Makoto and withdraws into her room.
"I want you to leave them alone. Fufufu, that would be easy with this."
What he got was a certain event ○ device.
He decided to use it for his sisters when he learned that the acquaintance he had obtained earlier was free to manipulate his terrible sister and earn pocket money.
Will he be able to freely manipulate his two ugly sisters using the event device?
