Jack always stays calm in any situation.
He is extremely cruel and doesn't hesitate to kill people.

At 15 years old, Jack finished a "perfect crime" in London in 1888.

In the "Undead Murder Farce" story, he appears as a young man in his early 20s who is part of the Banquet group.

Jack’s fighting skills are very powerful, even better than another half-demon, Tsugaru Shinuchi.
His main weapons are blade-like hand knives on both arms.
He can slice through people as sharply as a real blade.
After taking Aya Rindo’s immortal body, Jack’s body got stronger and gained healing abilities and super sharp senses like a vampire.
