Short Summary
Crowley Eusford tests a Demon Army sword against Chess Belle and suspects a high-ranking vampire traitor has been providing information to the humans.

The surviving human teams regroup. Guren leaves Aiko Aihara's team behind to direct late soldiers to Nagoya Airport while he takes the other squads to rescue hostages.

A few more soldiers arrive at Aiko's location, but vampires suddenly arrive in two large helicopters and capture everyone. Aiko orders them to commit suicide. Mika prevents her from swallowing poison, leaving her as the only survivor. She decides to trust Mika when he address Yuichiro as "Yu" and tells him Yu's location. With Mika acting as her interrogator, she tricks the other vampires into going to the botanical garden in Higashiyama Park. With some persistence, she persuades Mika to kill her.

Mika separates from Lacus and René and takes five soldiers with him to City Hall while claiming to doubt words from a human.
