Satoru Yotsumura

**Satoru Yotsumura** (四ヨツ村ムラ暁サトル, *Yotsumura Satoru*?) is the former No.2 of the JAA, a former founding member of the Order and professor emeritus of the JCC. He now works against the JAA after he was banished by them.

## Appearance

Yotsumura is a middle-aged, unshaven man with long, unkempt hair. He has tired, emotionless eyes which are often obscured by the bucket hat he wears.

Yotsumura wears a wrinkled plaid shirt under a nondescript, black jacket and black pants.

After his fight against Shishiba he gains a scar on his left check.

## Personality

Yotsumura is a laconic individual. He is also calm in the midst of battle, casually commenting that three active Order members was too many to fight. Yotsumura is highly indifferent, even in combat and hardly caring that his son Amane saw his mother's death.

Despite this, he appears to care about his son like any normal father, willing to kill his wife to save him. As see in a flashback, he smiled serenely while cradling his infant son and spent time with him, teaching him how to use his signature weapon. Furthermore, Amane's grandfather, Byodo, holds no resentment towards Yotsumura.

Yotsumura desires to walk freely again, hence his reason for trying to destroy the JAA. However, he doesn't fully agree with Slur's ideals and criticizes the idea that Slur's followers are revolutionaries.

## History

In the past, Yotsumura was a founding member of the Order alongside Kindaka, along with being a teacher at the JCC. At some point in time, he retired from the JCC and married fellow assassin Shino Yotsumura and had a son, Amane.

Yotsumura was the mentor of Shishiba. Around this time, he was assigned a mission to eliminate conspirators seeking to kill the chief of the JAA. Upon getting home, he found out that Shino was one such conspirator, marrying him and having Amane only to use him as leverage for the plan. With his son in danger, Yotsumura killed Shino just as Amane woke up.

Eight years ago, he was banished from the Order and sentenced to death for attempting to kill JAA executives.
