Demining: False Narcissus, one soul and three bodies setting
Tsushima Yukiho has a big secret. She has three bodies and is someone's sister.
In the beginning, she was in a different place, so she didn't need to worry about being disliked or targeted by her brother in another body.
But after arriving in Yokohama:
Edogawa Ranpo didn't like seeing these two guys who stole his sister. Even if he listened to the president and told them not to do anything bad, he would never look down upon them.
Edogawa Hina wanted to shout, "Brother, that's me, brother!" What are you doing to me?
Dazai Osamu makes trouble in front of Nakahara Chuuya every day, while Nakahara Raku and Tsushima Yuki sit close together and whisper.
Dazai Osamu and Nakahara Chuuya reached a united front: separate them first and then deal with the eyesore in front of them.
My sister must never be with this little slug/bastard mackerel sister!
Me: Cow, can't I like myself?
Intention: Family and friendship
