(W) Toru Shirogane In a corrupt dungeon city, a man and the woman who owns him live out their lives. Arwin, the Princess Knight, is like a spotless crimson flower among the filth of this place. Matthew, one of the local adventurers, is among the lowest of the low, as far as anyone knows. He's a weak fighter and a coward, and he spends his money on alcohol and gambling. But no one knows the truth-he serves his princess knight, and he'll get his hands as dirty as he has to for her sake.
