Personality
Jonah has a sadistic and twisted personality, showing no remorse in killing someone and bathing in their blood. He seems to have an obsession with art, and when the process of his Ignition Ability doesn't go according to plan, he has no remorse in killing them by exploding their face.

Abilities
Jonah is a Third Generation, giving him the ability to ignite and manipulate flames from his palms and fingers. He can use his Ignition Ability to change the appearance of people's faces. He executes this process by using heat to control the blood flow in people's faces, and makes the capillaries and lymph nodes expand, and then uses localized edema to change the shape of people's faces, something he commonly calls art. Using this same process, he can overheat somebody's face and cause it to explode.

Asakusa arc
Jonah uses his ignition Ability to change the face of three individuals to pose as Takehisa Hinawa, Akitaru Ōbi and Hikage, indirectly tricking Benimaru into thinking the 8th were enemies. Sometime later within a building, Jonah uses his ability to change an individuals face. Dissatisfied with the result, he kills the person in front of his partner. Afterwards, he and two other White Hoods begin attacking Asakusa. With Haran's fall, Jonah and Arrow departed, and informed their leader of what happened.
