Sekai Project anime adventures

From visual novels to mech action, these Sekai Project releases let you follow heartfelt stories or build suits and fight invasions.

If you enjoy anime-styled games with strong stories, these Sekai Project titles give you different ways to play within that style. Mahou Arms puts you in fast melee combat against otherworldly attackers, while M.A.S.S. Builder lets you design powered armor and command it in tactical battles. For something calmer, Amairo Chocolate 2 lets you spend time with cafe coworkers and follow their daily conversations. Across the collection you can switch between action, strategy, and relaxed visual novels without leaving that colorful look and character focus.
