this guys existence is weird. usually there are type A and type B demons.. but hes... BOTH?? *vine boom sound effect* yup hes the only known type AB demon (for now). its like having a cat-dog hybrid .it rlly shouldnt work. because of that his body is unstable and if its not held together by these special screws his shapeshifting abilities just burst out uncontrollably and his limbs morph into horrible twisted flesh consuming everything it touches. despite his high danger level 19 has a cheerful personality and enjoys the presence of other demons and even humans, although he doesnt always understand the concept of personal space. technically 19 isnt his name.. its just his inmate number but since he doesnt know his real name he just accepted it. why is he in prison anyways? well its also because of his unique AB type. they keep him there so hes less dangerous and to do tests and studies on him.
