To Love Ru Deviluke's Rival

Xavier Clark is a 15 year old otaku who moves to Japan, and transfers to Sainan High as a freshman. While there he meets the tsundere princess, Nana Astar Deviluke. They become good friends and eventually she invites him over to help her study for the upcoming social studies test. But during his stay he shows his true colors which makes Nana regret befriending him in the first place. Momo feels the same as well, but for a completely different reason. There was definitely something off about the boy named Xavier Clark, but what could it be? With his eccentric personality and charmingly(?) good looks, it isn't easy to figure out, but Momo is determined to dig up the truth behind him and his puzzling past.
