All-Star Battle R/Keicho Nijimura

"Once I beat this guy, my life will finally begin! (こいつを殺した時にやっとおれの人生が始まるんだッ！)"

Keicho Nijimura (虹村形兆), along with Bad Company, was confirmed for as the third playable DLC character on March 3, 2023, and is presumably set to release in spring. Like the rest of the DLC characters, he is included inside the game's season pass, and therefore also the Digital Deluxe Edition.

Having neither previously appeared in nor  as a playable character, he has an original moveset based on his appearance in Diamond is Unbreakable.

Tomoyuki Shimura reprises his role as Keicho's voice actor from the Diamond is Unbreakable anime, with new audio recorded for All-Star Battle R.

Gameplay
Keicho uses the Stand (スタンド) Battle Style, fighting foes with Bad Company (バッド・カンパニー). During a fight, he can use several different attacks of his that were featured in Diamond Is Unbreakable.
