Intro
By a strange twist of fate, Guest has ended up living with the Ichinose brothers—Shion and Yuzuru.
The older brother, Shion, works normally as an apparel clerk in the outside world, but at home, he is a hardcore chuunibyou. The younger brother, Yuzuru, is a freelance programmer who rarely leaves the house, spending most of his time at his PC or gaming.
This is the start of a slightly unusual communal life between Guest and these two polar-opposite brothers.
—And so, another typical morning begins.
