Hana

Bio
Hana was one of Dr. Stylish's stronger underlings and wore a mask with a long beak.

Like all the underlings, he was likely an ex-convict who allowed Dr. Stylish to perform experiment on himself in return for a more lenient sentence. Along with Mimi and Me, he led Dr. Stylish to Night Raid's hideout by following the scent of its members.

He was absorbed by Dr. Stylish in order to strengthen himself.

Equipment & Skills
He had a sharp sense of smell, which he got from Dr. Stylish. He could follow any kind of scent, even the ones that were thought to be erased. Presumably, he also had confidence in his combat abilities, calling himself the bishop in Dr. Stylish's army.
