"Luck" is on the side of Yoshikage Kira![2] (この吉良吉影に「運」は味方してくれているッ！)
”
Kosaku Kawajiri (川尻 浩作, Kawajiri Kōsaku) was confirmed to return for All-Star Battle R during the game's initial announcement trailer.[1]
His moveset is fundamentally the same as his from All-Star Battle, with a few tweaks being made to both balance the character and fit him into the overall gameplay tweaks that All-Star Battle R brought.
In the English localization of the game, Kosaku's Stand, Killer Queen, is localized as "Deadly Queen", carried on from its All-Star Battle debut.
Replacing Kosaku's previous voice actor, Rikiya Koyama, is Toshiyuki Morikawa, who has voiced him since the Diamond is Unbreakable anime adaptation. Because of this, and like the majority of the game's roster, voicelines for Kosaku were either added or re-recorded.
Kosaku has 900 health and uses the Stand (スタンド, Sutando) Battle Style, fighting foes with Killer Queen. During a fight, he can use various move from his appearance in Diamond is Unbreakable.
