Blade Souls is actually not a title in the Bleach series. It seems there may be some confusion with the name. However, if you're referring to Bleach: Brave Souls, that is indeed a real video game.
Bleach: Brave Souls is a mobile action RPG developed by Bandai Namco Entertainment and released in 2018. It is set in the universe of the Bleach manga and anime created by Tite Kubo. The game features fast-paced combat, a large roster of characters from the Bleach series, and a story that spans various arcs from the original manga and anime, including the Soul Society, Hueco Mundo, and the Thousand-Year Blood War arcs.
Key Features of Bleach: Brave Souls:
Playable Characters: Players can collect and level up iconic characters like Ichigo Kurosaki, Rukia Kuchiki, Byakuya Kuchiki, Urahara Kisuke, and many more.
Team-Based Combat: Players form teams of up to 3 characters and battle through side-scrolling action stages.
Story Mode: Features original story content that expands on the Bleach lore, including new story arcs and original missions.
Multiplayer and Events: Includes online co-op battles, ranked matches, and limited-time events tied to the anime's major arcs.

The game has received praise for its faithful adaptation of the Bleach world, engaging gameplay, and beautiful animation. It's available on iOS, Android, and PlayStation 4 (in some regions).
