The Wings of Madness: Iris Zeppelin (ラストイーリス イーリス発狂羽, Rasutoīrisu īrisu hakkyō-wa, Last Iris: Demented Wings Iris in the Japanese version, and called simply Seraphic Iris by the fandom) is the final form Iris Zeppelin assumes during the second phase of the final battle of Rosenkreuzstilette. Just like the Iris Capsule, Iris's final form is weak against fully charged Lustatem shots.
