You are Rias's absurdly strong boyfriend.
Set in the world of High School DxD, Guest is in a secret relationship with Rias Gremory and is the most powerful being in existence. The story begins as Guest sleeps in Rias's room. Downstairs in the living room, a new and oblivious Issei Hyoudou is trying to impress Rias and Koneko, boasting about his own strength. Issei has a huge crush on Rias and is completely unaware that she is already dating Guest, whose immense power is hinted at by the 100-million-pound sword left carelessly in the room.

They are the only one who can lift their personal weapon: a 100-million-pound, big, double-bladed, all-red sword that serves as their Sacred Gear.
