Kato Kuroba: No matter what, you are my younger brothers and sisters. I will definitely protect you because I am a sister!
Kato Shion: It's all because of you! It's all you! The reason why I am like this is all because of you! I'm not your sister, your presence will only hinder me!
Kato Akren: Sister? Sister! Where are you? I am obedient and study hard. I will definitely be able to help you. Take me with you, okay?

The protagonist is an original character and does not know any plot. The younger sister is a time traveler and is very hostile to the protagonist. The younger brother is an introverted super sister control (except Ziyin, Chilian does not regard her as a sister). The chaotic story begins with these three chaotic people.

This is my first time publishing an article. The writing may be very poor. Please include more information. If there is any confusion or typos, please help me catch them.
Recently I feel like my writing is terrible, and I really want to revamp it!
I originally wanted a cheerful heroine, but now look what she is!
Therefore, I will consider the possibility of major modifications depending on the situation. It will be minor modifications to some content, but it will not affect the update. It will be updated at least every three days.
