Seraph of the End

Four years after escaping, Yūichirō is part of the Japanese Army and is eager to become a member of their special vampire hunting force, the Moon Demon Company, but his reckless behavior leads him to be suspended, until a vampire attacks the local school prompting him to face the enemy against orders.

Instead of dying with the rest of his friends, Yūichirōs best friend Mikaela was transformed into a vampire by Krul Tepes, the queen of the vampires and now works as her aide. Meanwhile, Yūichirō finally begins his training to become a member of the Moon Demon Company.

After passing the final test, Yūichirō and his classmate Shihō Kimizuki obtain their own Demon Weapons, but when Yūichirōs friend Yoichi Saotome ends up possessed by his weapon, the duo must find a way to bring him back to his senses without killing him.

After successfully clearing a vampire nest and rescuing the humans held captive, Yūichirōs party sets for the human base in Shinjuku, unaware that the vampires are attacking there. Upon arriving, they come across one of the vampire nobles, and find themselves at mercy of his overwhelming power.

Yūichirō and Shinoa get separated from the others and after taking a wounded soldier to be treated, they regroup to assist Gurens party. In the occasion, Yūichirō and Mikaela finally meet again.

Yu has been in a coma for five days when Shinoa confronts Guren about special drugs in Yus pill. He tells her to go and wait for Yu to wake up if she really cares for him. During the seventh day of his coma, Yu wakes up. He finds out that Mika retreated with the other vampires. Once all his friends have gathered he thanks them and apologizes to them. At the end of the episode both Yu and Mika promise themselves they will save the other.
