Rosenkreuzstilette ~Grollschwert~ (ローゼンクロイツ スティレッテ グロールシュヴェート, Rōzenkuroitsusutirette Gurōrushuveeto) is an alternate mode to Rosenkreuzstilette that can be played after inputting a secret code on the [erka:es] opening screen. In Rosenkreuzstilette ~Grollschwert~, the main protagonist is Grolla Seyfarth instead of Spiritia Rosenberg and plays through a slightly different storyline, although featuring the same stages. The bonus game can be accessed by pressing Left, Right, Weapon Change R, and Weapon Change L (with default keys, ←, →, S, and A) at the [erka:es] logo screen, in that order.
