Nanatsu no Hikan: Senritsu no Bishou

The player can control one of two characters: Kei and Reina. The game can be played in either first person, third person, or fixed camera angle views. Kei's levels are more action based, while Reina's are more adventure-based. There is also a unique multiplayer cooperative mode where one player controls Kei and the other Reina. This mode is different from the single-player mode, as it is much shorter and objectives, monsters, and events are all altered.

Friends Kei and Reina land on a mysterious island and search for their friend Ernest. But along the way, they encounter many different monsters in the different mansions they discover. It's up to them to defeat these foes, find their friend, and understand the mysteries of the island.
