When a demon's castle darkens the land, two sisters challenge its halls. Together they can break the curse. Players take control of the two sisters with different attacks and capabilities to challenge the demon castle and the bosses waiting within. Discover new routes through the castle using the sisters' unique abilities! The stars of Grim Guardians are the long-distance focused "Shinobu Kamizono" and the close-range brawler "Maya Kamizono." Players will need to consider the situation when choosing which sister to control as they make their way through the castle, investigating the mystery of what happened to their school and its students. Other features include 2-player co-op with special actions, extensive difficulty options with the "Style System," unique changes on repeat plays, and most importantly the quality and challenge players have come to expect from Inti Creates titles, this time with a new gothic horror aesthetic.
