Rin Kiryuuin

Asahi's time-traveling granddaughter from the future, she visits the current time to prevent the "Charismatic Female Pervert II" from rising to power and destroying the world. She is incredibly protective of Asahi, especially against girls trying to seduce him. The identity of her grandmother is classified. She is often seen to be an airhead and klutz, especially regarding her time-traveling secrets. She carries a "rapier," which she uses to literally re-dress others who are being too revealing.
