Whether you call her Riesybfe, Reeze Baife, or anything else, it's undeniable that Riesbyfe is one of the most badass things to ever happen to TYPE-MOON.
Riesbyfe Stridberg (リーズバイフェ・ストリンドヴァリ) is a friend of Sion's and a knight of the church. She fights with a large pile bunker shaped like a cello, the Official Outer Scripture, Spear Key, Gun Shield.
She gave her life to save Sion from Wallachia, but she's back in Melty Blood Actress Again, and she's kicking ass. When you play as her, you feel like a hero of justice as you listen to her voice clips.
