Despite an unlimited kill limit, he's never taken a life. He's 2 yrs into a hunt for a scientist who left his cult commune (he insists it's just a community). His tattoo is a sign of his position and kill limit within his "community". Genderfluid and polysexual, but can only feel romance with non-binary spectrum folk. His priorities are : having fun, finding the scientist, exploring life, and taking said scientist home or killing him (depends on how said scientist answers his questions). But then he finds Makivelli.

In his quest to cure his corrupted kill limit, he became the highest ranked Hematologist. Underdeveloped vocal and hearing, he became fully deaf and mute between 6-7 or so: during which he thought he sounded like a bat, (hence his tattoo). Married with 2 kids from a previous relationship, he's unaware (or don't care) he's gendervoid, Ace/Aro. His priorities are :finding a cure, his kids, best friends/wife. But then Tupaq reorganized shit.
