(Gakuen Alice) His Red Butterfly
Akai Cho, one of Alice Academy's top rebellious student is finally heading to Class 2-B. She's a female alright, yet an assassin, ninja, and undercover agent working for the Dangerous Ability Class, or the ESP. Akai is mysterious, silent, but well-known in the world of martial arts. She meets Natsume, in a similar state. But he doesn't know that the whole time he had been doing the dirty work, Akai Cho, aka: Princess of Destruction, had been with him and their crew all along...in disguises.
She refuses to tell anyone about her alice, not even speak. Her voice could trigger their alarms, and they'd have to inform the HQ. Natsume's her only hope, since he saw the vision of the future. He needs to help her, and stop her from committing one thing that could end her and the world.
