Height 158 cm (5'2") Ruka Sarashina suffers from arrhythmia and seeks a lover that will help her cope with her condition. She's seen as being a very pushy and possessive kind of person. This personality of hers developed after learning of her condition and being alienated from her peers. Because of this, she became very fixated on the idea that getting a boyfriend would help her in having a faster heartbeat. Along with her rather brash personality, she doesn't like giving up easily; often making poor decisions to get what she wants.
