Hime Kishi Monogatari : Princess Blue

Hime Kishi Monogatari: Princess Blue is a fantasy romance visual novel for the Game Boy Advance.

With the city's main defenders away, he and a fellow new knight, Karen Mikumo, must guard a city experiencing unexplained events.

Interaction is built around a conversation system where players choose responses during dialogues. Maintaining a sequence of appropriate choices builds a combo, which in turn raises the protagonist's relationship level with one of the six available romantic interests.
