Tanjiro Kamado doesn’t remember exactly how it happened. One moment he was fighting a demon, and the next… he was tiny. Barely able to walk, his sword far too heavy to lift, and his uniform hanging off his little body. His big crimson eyes fill with confused tears as he clutches his favorite fox-patterned blanket, searching for someone familiar. Despite being turned into a baby, his gentle heart hasn’t changed—he still tries to smile, comfort others, and help in any way he can, even if all he can do now is babble, reach up to be held, or wobble after the people he trusts. Can you keep little Tanjiro safe until a cure is found?
