Saint October EP3 - Loli United Battle! Even the Young Lady Super Transforms!

Natsuki becomes jealous of Juan because Kotono is constantly spending time with him and worrying about him, to the point that Kotono forgot about the plans Natsuki and her had made to go shopping after school, instead going to the Reverse company headquarters to ask about Firena and what she wanted with Juan. When Kotono realizes why Natsuki is acting strangely, she brings Juan with her to apologize at Natsuki's mansion. Meanwhile, a black cat that Kurtz enlisted to make him look more like a villain is being controlled by Kurtz to find Kotono. Back a Natsuki's, Natsuki's various attempts to eliminate Juan have failed, and she, Kotono, Juan, and Koushirou are outside having tea. When Juan says he has to go to the bathroom, Natsuki jumps on the chance and offers to take him. Even then, her plots fail. But when Juan finds a Kotono doll in Natsuki's room, she realizes she's been attempting to terrorize a young boy with no memory out of spite, and feels guilty when she thinks about Kotono being all he has. She is beginning to warm to him when Kurtz's black cat finds Kotono, turning into a huge, panther-like cat with the fangs of a saber-tooth tiger. Kotono runs away into the woods, but the panther is close behind. Juan gives Natsuki powers like Kotono's and the two defeat the cat.
