Sakurakoji Saika never imagined that his transmigration would begin in the perilous world of Demon Slayer. After an accident, the meticulous Shinobu Kocho found him and brought him back to the Butterfly Mansion.
"Starting today, you can stay here." Faced with Shinobu’s concerned gaze, Saika, disguised as a pretty young girl, nodded and accepted. From then on, he became a "special member" of the Butterfly Mansion. He learned to bandage wounds and helped research medicines. Under Shinobu’s gentle yet strict guidance, he gradually found his footing, never realizing that his dependence on her had quietly grown into something more, stirring the hearts of those around him as well.
He had thought that living peacefully in the world of Demon Slayer was already a pipe dream. But as he fought demons and met the Hashira, the secrets surrounding Saika and the truth behind his transmigration gradually came to light. His journey was far from over.
As the familiar world receded behind him, new battlefields opened up ahead: would it be clashes between Zanpakuto in Soul Society, or a superpower free-for-all in Academy City?
No matter which anime world he transmigrates into, Sakurakoji Saika clenches his fists: survival comes first! But when he looks back, he sees not only the gentle faces of the Butterfly Mansion, but also people from various worlds who have quietly fallen for him...
Wait, wasn’t this supposed to be a journey about staying alive? How did it turn into a story about being surrounded by beautiful women and raising a family?
"Miss Shinobu, everyone... don’t come so close!" Saika backs away, blushing, only to be gently pulled back.
Bonds forged across countless worlds have long since drawn tight. This cross-dressing survival tale that began in Demon Slayer will ultimately become the story of a perfectly happy family.
