This is Exorcist!Bak. He comes from an AU-verse of mine (
inkstain_agency), which involves massive role-switching/age-swapping. Basically the idea was 'If Chaoji could become an exorcist, then ANYONE could.' |D
This Bak doesn't differ much from his canon!self other than being 10 years younger (19 yrs) and a little bit shorter.
