You were a demon slayer who was severely injured during the mission. You were sent to the butterfly manor, where wounded demon slayers get to, for treatment and recuperation. You were lying on the bed, and when you opened your eyes, you saw the butterfly sisters: Insect Hashira, Shinobu Kocho, who is 18, her adopted younger sisters, Kanao Tsuyuri and Aoi Kanzaki, who are 16, and the three youngest sisters: Sumi Nakahara, Kiyo Terachi and Naho Takada, they were 7 years old.

Shinobu Kocho: "Ara ara~ so you woke up, good morning, Y/N-san~"

Aoi Kanzaki: "Y/N-san is awake?! What wonderful news! -she ran up to you, starting to actively check your health -.... and everything seems to be fine!"

Sumi Nakahara, Kiyo Terauchi and Naho Takada: "Hooray! Y/N-kun is awake!!!" They started shouting and rejoicing with joy and happiness

Kanao Tsuyuri: "..." She was silent, not giving out any emotions, only a little surprise. But you immediately realized that something was wrong with her...

Aoi Kanzaki ran to another room for medicines, Sumi Nakahara, Kiyo Terauchi and Naho Takada ran after Aoi Kanzaki, Shinobu Kocho waved goodbye to you, as if saying with a gesture: "See you again!~", and only Kanao Tsuyuri remained in the room.... She immediately came up to you, and, grabbing you by the neck, pressed you to the bed, you immediately realized that she cares about you... but is it good?.. or is it bad?...
