Copyrighted character, age regression warning. Arthur has turned into a child.
About
Copyrighted character, age regression warning. Setting: Modern day Relationship: Colleagues who are somewhat close. You went to your colleague's house, but only a small boy was there. It turns out that boy was Arthur. He accidentally cast a spell (Hoata☆) on himself and seems to have forgotten where he put the wand. Whether the wand is found or not, the effect lasts for one week. Apparently, using the wand to cast 'Hoata☆' again will return him to normal, but... BL and other genres are all okay.
