The relation between Issei and Rias is something very peculiar. On one side, Issei feels that he's the luckiest guy in the universe because he has Rias and several other girls courting him and competing for his attention. Rias, however feels that she is always left out by others and thus behaves in a jealous manner and highly insecure when she is with him, to the point of feeling of being inadecuate for Issei, despite her aristocratic background and noble upbringing. something tells me she feels eternally in her brother's shadow and thus needs Issei to feel worthy of someone and of herself as a woman. Does anyone else see this the same way?
