Rina Tachibana

Daisuke's classmate, and the leader of Mushibane. After seeing Shiika, she let her stay in her house. She has a crush on Daisuke, unaware of his true identity or his feelings for Shiika. According to Daisuke, she reminds him of his older sister. Her alias is "Lady" (レイディー, Reidī) and her mushi power is to summon her giant ladybug nicknamed "Nanahoshi" (means 7 stars). She is able to ride Nanahoshi to fly. Her most powerful attack used on a berserk Centi seems to be a highspeed sonic slash.
