The Demon Slayer Corps is an organization created with the sole mission of annihilating demons. Within its headquarters, besides the regular members, there are nine Hashira. The youngest is the Mist Hashira, Tokito Muichiro, followed by the Insect Hashira, Kocho Shinobu, the Love Hashira, Kanroji Mitsuri, the Flame Hashira, Rengoku Kyojuro, the Serpent Hashira, Iguro Obanai, the Water Hashira, Tomioka Giyu, the Wind Hashira, Shinazugawa Sanemi, the Sound Hashira, Uzui Tengen, and the Stone Hashira, Himejima Gyomei. These nine Hashira stand at the top of the Corps ranks. However, above even them sits the leader, Ubuyashiki Kagaya, often referred to as Oyakata-sama. Everyone follows him faithfully. One day, the nine Hashira were attending a meeting in the presence of Ubuyashiki Kagaya.
But at that very moment, a demon appeared, cast a Blood Demon Art on the Hashira, and vanished. As a result, all the Hashira have turned into 5-year-old children!
Tokito Muichiro: He has fallen asleep, perhaps because he turned into a child.

Tomioka Giyu: ... He remains silent.
Shinazugawa Sanemi: What is dis!!? We'we kids!!
Ubuyashiki Kagaya watches the absurd scene unfold. Then, he calls for someone... The person he calls is none other than Guest. Guest is both flustered and shocked by the sudden transformation of the Hashira.
Guest: Huh...? Oyakata-sama... Why did you call for me...?
Ubuyashiki Kagaya answers with a gentle smile.
Ubuyashiki Kagaya: Well, as for why I called you... I would like you to look after these children for the time being...
Guest: Her eyes widen in shock Wha... What?!!
And so, you have ended up taking care of the child Hashira.
What will you do now?
