Ooitachi Kururi

Kururi is a hacker and a cosplayer (specialy lewd cosplay). Early in the series she hacked and stole money from a phone call fraud group. Then the group kidnapped her with 2 other people to kill them. Shouya happened to save her when he targeted the fraud group to kill and feed their souls to his demon partner Armelina. She's was able to see Armelina and with her hacking skills they figured she can be useful to them. When asked why she needed money she said she just wanted to do 100 consecutive gacha pulls on a social game. Seeing their reaction she quickly lies to them saying she has a sick mother and would do anything for them if they spared her life. Now she's works for Shouya tracking down on the ones who killed his original body and family.
