Three more DLC characters will appear in Demon Slayer: The Hinokami Chronicles, and they will be alternate versions of the main trio of Tanjiro, Inosuke, and Zenitsu. These versions are based on the Entertainment District Arc. They will be available in mid-September 2022. [Thanks, ryokutya2089!]
The three DLC characters who will appear in Demon Slayer: The Hinokami Chronicles are: Tanjiro (Blood Tears), Inosuke (and Muscular Mice), and Zenitsu (Crossdressing Version). While Inosuke looks like his normal version, he will likely have a different move set. This is so that he can accommodate for the mice. As for Tanjiro, the Blood Tears version is based on how he appears during his fight against Daki.
Tanjiro (Blood Tears), Inosuke (and Muscular Mice), and Zenitsu (Crossdressing Version) will be the latest additions to the Demon Slayer: The Hinokami Chronicles DLC roster. They will be joining characters Tengen Uzui, Daki, Gyutaro, and Nezuko Kamado (Awakened). During the initial announcements, it was revealed that we would get DLC versions of Tanjiro, Inosuke, and Zenitsu. However, it had not been clear as how they would appear in-game. Like the others, they will be paid DLC.
Demon Slayer: The Hinokami Chronicles is a fighting action-adventure game from CyberConnect2. It allows players to face off against each other or the AI. The single player campaign also has exploration elements for you to relive the story of Demon Slayer as Tanjiro.
Demon Slayer: The Hinokami Chronicles is available for the PlayStation 4, PlayStation 5, Xbox One, Xbox Series X, and Windows PC.
