The Midnight Maiden War

I, a university student who moved to Tokyo and is living alone for the first time. I has no friends. I has no girlfriend. The lectures at the university were horribly boring, and I was always looking at Tokyo Tower on the way back from his laborious job. While being attracted to the ruthless, dignified and intelligent Senior, whom he meets in the "Hide and Seek Circle" that he secretly falls in love with. Meanwhile, I meets a man called Black Suit, who is an extremely charismatic and mysterious person. Little did I know that the two people he met would bring excitement to his mundane, humdrum existence.
