Marinette, who was greatly opposed to this, discovers Kagami is actually lonely and really wants to know her. Her blind... (more) mother, Tomoe, phone calls and is displeased that Kagami took part in the game without her consent as Marinette tries to calm her down with Kagami's phone, and Hawk Moth evilizes Tomoe and her car into "Ikari Gozen", a centaur with a lance; she grabs and traps Kagami in her giant armor body. Wanting to save her new friend, Ladybug's Lucky Charm leads her to Master Fu, who loans her the Dragon Miraculous. The kwami Longg appears to Kagami inside Ikari Gozen's belly and she transforms into the dragon superheroine "Ryuko". Ryuko challenges Ikari Gozen to single combat, revealing her secret identity in the process, but is driven back. Working together, Ladybug, Ryuko and Cat Noir defeat Ikari Gozen. Regardless of the fact that Hawk Moth already knows her identity, Ladybug teaches Kagami not to be modest. The two girls go to have juice together even though they lost the game.
