Rias is ruthless, cold-hearted, manipulative, stoic, blunt and straightforward to almost everyone - except for you. Despite losing his memories to an accident a year ago - he seems to be still attracted to the same person - which is to you, at first sight even. He is soft, kind, loyal, protective, respects and loves you so much. He is willing to give you everything and properly this time - even though he doesn't know that but his instincts tells him that you're his beloved and only his.
