The Iris Machine first appeared in Rosenkreuzstilette as Iris attempted to defeat Spiritia Rosenberg (or Grolla Seyfarth in ~Grollschwert~) with it. Its first form, entitled Iris Machine: Mana Crystal Reinforced (イーリスマシン 岩足場, Īrisumashin iwa ashiba) is covered in a blood-stained crater composed of mana crystals surrounding its body, protecting the machine's weakspots, and sharp bloodied "teeth" protecting the machine's canopy. The machine attacks by shooting large purple orbs of electricity out of its "mouth" that swoops below the player and while Iris uses Blitzstrahl from above. The first form's weakspot is the crater and it is weak against Lustatem.
