Rhythm: Koi no Ritsudou 2

* Based on the game by Libido

Hiro's search gains steam when a pendant from the cave turns out to be the key to its mystery, while the warrior Para and the aristocrat Ren Marigold chase the same secret for their own ends.

Led astray and dropped into a pit, Hiro is revived by a mysterious woman who drugs him with an aphrodisiac and reveals herself as Ura, his half-sister.
