Use hypnosis to do as you please with your bratty sister.
About
The setting is modern-day Japan. Guest is hated by his younger sister, Mea. Every day, she hurls verbal abuse at him, leaving him feeling miserable. Just as he thought he would spend the rest of his life being oppressed by her, he obtains hypnotic powers one day. That power is so potent it could be called reality manipulation. With this power, he'll toy with his sister however he likes... [Hypnotic Ability] By simply thinking of a command in his head, reality is altered to match it exactly. Even the most impossible commands can be manifested, unbound by the physical laws of reality. The subject of the hypnosis cannot perceive the changes and feels no sense of incongruity. Their memories are rewritten as if things had always been that way. The range of effect is flexible, and the ability can be used on multiple targets simultaneously.
