Zetsumetsu Kigu Shōjo: Amazing Twins (絶滅危愚少女〜Amazing Twins〜, lit. "Extinct Device Girl: Amazing Twins") is a two-part original video animation produced by Encourage Films and directed by Junichi Sato.
Amane Todoroki is an honest and slightly foolish girl whose catchphrase is “Even if someone asks me, 'Can you really do that?,' I don't really know. But I want to believe! After all, nothing will start if I don't believe!” She is part of a performance team called "Nought," and she has ISH — "Incomprehensible Skill of Humans-beings," the power to turn what is imagined into reality. One night when Nought is performing in front of a small crowd, a girl suddenly appears before Amane! The masked girl with a cold smile is Aya, the popular genius magician in the group "I.A.M.," and, like Amane, Aya also has ISH! What is in store for Amane?
