Daizen Matsushige

is a former thief that had settled in Konohagakure as a shopkeeper.

Background
Daizen had committed various thefts and murders during his time as a thief. He had once encountered a shinobi, the father of Hibiki and Kodama, who he had killed, though not before the latter left a cross shaped scar on his chest. Daizen would later start a new life owning a grocery shop in Konoha.

Abilities
Daizen is a retired shinobi, but remains skilled in Wind Release. Thorough the years, he successfully stole and killed, concealing his involvement by pretending to be a witness to his own crimes.

New Era
When Mitsuki had asked for the whereabouts of his missing cat, Daizen offered to let him know if he saw any similar looking cats. The next day, a customer talked to him about the attacks on ex-shinobi, also bringing up that Daizen was a shinobi as well. Daizen claimed it was only a desk job. Later, he found Mikazuki behind his shop and scared him off.

At night, as Daizen closed his shop, he was attacked by Hibiki and Kodama. However, he anticipated their ambush and fought back, thinking that by killing them he would be hailed as a hero. As Daizen was about to kill them, Mitsuki intercepted him. Daizen confirmed to Team 7 and Kōtarō Fūma that the duo were the attackers. Hibiki and Kodama accused him of being their father's killer and only wanted to see the scar on his chest. Daizen revealed to everyone no scar, though it is revealed as a ruse when Mikazuki scratched off prosthetics covering it. Though Sarada Uchiha didn't think it was enough proof, Mitsuki believed their claims and pointed out the injury he inflicted on Hibiki, and Kōtarō suggested comparing it to the ones inflicted in the unsolved robberies and murders. Daizen attempted to flee but was stopped by Mitsuki.
