Single-player, story-driven JRPG that pairs Ichiban Kasuga and Kazuma Kiryu in an emotional, often irreverent narrative mixed with many minigames and side activities. Combat uses a turn-based "Live Command" system with movement-based positioning and a job/class system; players explore Yokohama and Honolulu and can take part in noncombat activities like karaoke, Dondoko Island island-building, Sujimon collecting, and delivery minigames.
