All-Star Battle R/Kosaku Kawajiri

"Placeholder (目撃者は生かしておけないよ… 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) was confirmed to return for during the game's initial announcement trailer.

His moveset is fundamentally the same as his from, 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 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.

Gameplay
Kosaku has 900 health and uses the Stand (スタンド) Battle Style, fighting foes with Killer Queen. During a fight, he can use various move from his appearance in Diamond is Unbreakable.

Outside of the All-Star Battle Mode, Kosaku has unique dialogue for both his match entrances and victories when facing certain characters.
