Gatekeeper Trio

The Gatekeeper Trio (門番トリオ) is a group of brothers-gatekeepers that Tibby and the player encounter in Rhythm Heaven Megamix. They consist of Paprika (レドロン), Saltwater (ブルック) and Saffron (イエモン). They each wield a fire lit staff and are all dressed in colored cloaks and wear color matching aviation caps and goggles. Nothing is known about their pasts.

Story

Saffron owns a shop in the cafe where the player buy goods such as shop games, rhythm items or CD's with their coins and Flow Balls.

Saltwater owns the museum where the player can play all the games in one place, view your rhythm items or listen to their CD's. They can also check their badges, watch the credits, and see the mascots they've unlocked.

Paprika hosts the Challenge Train, where the player must complete challenges by themselves or with friends, and the Perfect Campaign, where the player has a chance to achieve a Perfect rating on a Rhythm Game.
