Ligene

Оригінальне ім’я: リージェン

A mysterious girl from the future who has been assigned to help Kotaro prevent Kaho's death. She works as a Time Patroller, or TP, and regularly travels through time on assignments. It was Ligene whom Kotaro encountered and covered him with the multi-colored powder. Although she is faced with a serious task, she hardly seems to realize the gravity of it, constantly joking and playing around. A bit ditzy and irresponsible, she is also very curious, fascinated with the time period Kotaro's living in. In the end of the anime, she kisses Koutaro, so maybe she loves him like Kaho, Ai, Mana and Tomomi.
