She chuckled. "Yeah, but yoh nevet dreamed of kissing Daimond." Krystal smirked. She wouldn't let sere get the upper hand. "Oh, its on now, sister." She said simply, landing on her feet. Neither crystal could do her much damage. One was her oppisite, while the other had never affected her due to her powerful shadow magic.
Krystal's fuku was changing as well, darkening to black, the only color visible was the the silver of her tiara. She glowed a bit as she brushed herself off, still smirking. So sere wanted to play dirty, huh? Well, two could play at that game. Her visor came down, and she began anylyzing the scene. She smirked again. "I've got it. Distract diamond aaron." She told him telepathically and he nodded, shooting bullets through the ship, casing small holes everywhere. It wasn't completely obvious which crystal was controlling her sister, but she had a plan that would weaken sere and diamond enough for her to purify them.
Krystal started with the first crystal, knocking it out with her wand. She went from each crystal to the next, until she reached the throne, taking spencer's hand and signalling everyone to destroy the throne. With each blast she could see diamond weakening. She pushed all her power into the destruction of the throne, using all her senshi's attacks in tandem with their own. It exploded and shattered all over the room, the shards causing monsters to appear. She readied her wand, but her cosmos senshi were already on it, monsters destryed easily.
Diamond was busy fighing with aaron, so he wasn't privy to what she was doing, and luckily the smashing of the crystals appeared to have weakened sere as well. Aaron had diamond pinned tona wall with his sword, the black crystal in his hand now shattered. "You will return serenity to me or die, diamond." He growled, knowing that the other had been weakened.
