(Same OC in Mujitsu, Mokoto. Just without a quirk.) Mokoto is Tanjiro's childhood friend, they were always happy! Til' one day...a demon attacked his home, friend, and family. Mokoto and Nezuko are turned to demons but Mokoto still acts as if he's human. He can talk, although he seems to have forgotten most of the words he knows, he can eat things other than human flesh, he doesn't seem to attack humans, and he can stay out in the sun. (Although he becomes extremely tired and sometimes falls asleep randomly.) What will happen now to Mokoto. How many hearts will he steal unknowingly.
