Kosaku Kawajiri

Kosaku Kawajiri (川尻 浩作 Kawajiri Kosaku) is a minor character featured in Part IV: Diamond is Unbreakable.

Appearance/Personality
Kosaku apparently had the same body structure and size as Yoshikage Kira.

None of Kosaku's interactions with any character is ever seen, but from his wife's comments he can be deduced to be a cowardly character who was never prepared to pay the rent on his house and got bossed around at work even though he worked everyday. Kosaku did not even get along with his son very well. He also hated his wife's food and would have divorced a long time ago if wasn't for his son Hayato, though they were not close. Described as someone who would not talk if angry, he would never ask for forgiveness and hated Shinobu´s cat, locking him outside of their house so he would not enter at night.

Kosaku did not have any unhealthy habits, neither smoking nor drinking. He was also implied from the Kawajiri family's reactions to be boring and to dislike mushrooms.

History
He was introduced to Shinobu by her friends, and she married him out of pressure from her friends as opposed to romantic reasons.

Diamond is Unbreakable
Kosaku was a person with the same body size as Yoshikage Kira. In an attempt to hide his identity, Kira dragged Kosaku into Aya Tsuji's Cinderella shop and subsequently killed him, forcing Aya to strip Kosaku of his facial features and then place it onto Kira's body. Kira then assumed his identity and started living with his family.
