Spending his days training to fight with his grandfather, Rumina is
also adept at avoiding the traps set up for him by the old man too! In
middle school, his martial arts skills were highly regarded by his
classmates, so he hopes a new start in high school will help him
attract a girlfriend of his own. Dedicated to his training, Rumina is
also highly competitive. Despite his violent streak, he is actually
very kind hearted and willing to help out anyone in trouble -
especially if they are a cute girl!
