Despite her love of modern military hardware, Ritsuko also displays a more sensitive and innocent side: she falls in love with the cute Pichi and maintained a belief in Father Christmas long after her peers had abandoned it and is also frightened to death of ghosts. Ritsuko carries a Heckler & Koch USP40, G36C Assault Rifle, PSG1 Sniper Rifle, a sheath knife and some C4. Her I.Q is 500. She also speaks fluently in English and German (source: Wikipedia) In the manga, she demonstrates a clear affection to Junpei and is shown to be extremely jealous when Junpei is approached by another girl romantically.
