For Sakuya to change into Garren, he inserts the sealed ♦A: Change Stag Rouze Card and positions the buckle in front of his waist. The belt expands automatically around his waist, like a deck of cards wrapping around. Sakuya makes an arm motion, clinches his fist and yells out "Henshin!" and flips a portion of his buckle. The buckle announces "Turn Up!" at this point. This causes a blue projection with a stag beetle image to come out before him, knocking Undead away. He then runs into the projection, which will complete the transformation into Garren.
