Iizuka

Iizuka is the field examiner of executions for the Chōshū Clan, responsible recording the group's kill. He was later revealed to be a traitor and spy for the Yaminobu, as a contributing factor in plotting the downfall of the Hitokiri Battosai. Iizuka attempted to skip country as soon as the trap was in place, but was murdered by Shishio Makoto after his ruse was discovered.
