Kosaku Kawajiri

just a bland, boring salary man. he is married and had a son, but they both resent him and he cant do anything about it. hes not the wisest with his money. quiet, sometimes nervous, bites his nails. when shown respect/kindness, he opens up and grows to be slightly comfortable. an acquaintance of kira yoshikage, but doesnt know that his friend is a serial killer. his wife's name is shinobu and his son is hayato. he doesnt like shiitake mushrooms.
