The Smile of Darkness.
Takako mysteriously appears at a bridge in Himeno's dream. The next day at school, transport demons hover in the sky, absorbing leafe energy to be sent back to Takako. Himeno wanted to apologize to Hayate for disregarding his concern in guarding her, but she ends up being distracted by her father Kaoru Awayuki. Himeno, sensing a demon larva when a blackout occurs throughout the city, brings Hayate to the bridge where Takako soon appears. While Takako leads Hayate to a cathedral, an electric demon forms and attacks Himeno. The other Leafe Knights come to the rescue. Himeno allows Mannen to merge inside of her, and she shoots a blast of ice through the electric demon. Takako promises that she will kill Himeno the next time they meet.
