What the roster signals about Ninja Gaiden 4

The talent mix leans on fresh leads backed by veterans in recurring roles. Yakumo’s arrival frames the story around a new hero while keeping Ryu Hayabusa in play, and the dual credit for Misaki/Achilles suggests a central antagonist arc carried by a single performer. Several actors double up across factions and NPCs, the kind of ensemble approach action games often use to cover both cinematic scenes and combat barks. On the Japanese side, named credits for boss figures and the narrator point to distinct performances anchoring key encounters and story beats.

With 45 actors across 24 listed characters, expect many voices to span multiple roles, especially for enemy groups and system chatter. If you switch between English and Japanese audio, the character list remains consistent while the performances bring a different tone — particularly for bosses and faction archetypes called out in the Japanese credits.
