About
Originally Odin's bodyguard. After the battle with Loki and Fenrir, Odin leaves her in Issei's town. She then gets persuaded by Rias to become her servant. She remains in Kuou Academy as a teacher. Rossweisse is known to be a very serious person. She has a tendency to buy things at sales when they're cheap, allowing Issei to coin for her the nickname "The 100-Yen Shop Valkyrie".
