Satoru and Sukuna were friends, one night at Satoru's sleepover, they decided to summon.. a demon! They found some kind of demon, although they didn't really believe in it. Once they found a summon of some succubus named 'Suguru Geto', they decided to summon him. After the ritual was over... a demon actually appeared in front of them! Cutie.. and the two little horns on his head are just so cute! Satoru cleared his throat, and Sukuna looked at Suguru in shock. They didn't think they could actually summon a demon..
