The Demon in Your Heart (Episode)

The Demon in Your Heart is the third episode of the anime series, Seraph of the End: Vampire Reign. It corresponds with chapter 3 of the manga.

Short Summary
Yu, Yoichi, and Shinoa go to a restricted area to save someone who was possessed by a demon there. Mika is revealed to be alive.

Long Summary
In a restricted site, Yuji (one of Yamanaka's companions) attempted to open a cursed dungeon, but Yamanaka stopped him before he could continue to do so. Meanwhile, Yu received a love letter from the girl who he saved from a vampire before, and is unsure how he should respond. Shinoa teases him that he should build a relationship, but she is serious to explain that humanity must increase in numbers in order to survive in the world.

Moving on, Shinoa shows Yu her Cursed Weapon, with Yu amazed by it's power and asked Shinoa to give it to her. When she refused, Yu decided to attack her in order to test the weapon's strength, though he pulled off a nice fight he was overwhelmed by Shinoa's Cursed Weapon.

Later, Yoichi is once again bothered by Yamanaka, this time they're asking to be his disciples. Yu tells them to leave seeing it annoying that they still had the pride to ask help from someone whom they bullied earlier. Yamanaka begs because he thought that Yoichi (now part of the Vampire Extermination Unit) could save his friend Yuji, who went into the Forbidden Chamber and never came back. Shinoa replies that action will lead to severe punishment (even death) and tells them to give up.

Regardless, Yu, Shinoa and Yoichi go to the chamber. Shinoa warned Yu not to try anything dangerous, but Yu rushed in anyway and tried to seize the cursed axe from Yuji (now controlled by a demon). When Yu got hold of it, he suddenly found himself back in Sanguinem with Mika, Akane and the other orphans. The orphans asked Yu to continue with their dinner, but Yu felt uneasy about what's going on, confused when he knew they were already dead. Mika and the others did reply that they are dead, and ask Yu to avenge their deaths. Yu however, knew Mika would not want that, and demanded that the demon show it's true colors and to stop pretending to be his family.

Yu wakes up, realizing that the demon had attempted to possess him, but to Shinoa's surprise, Yu managed to expel the demon just by his sheer will. This would mean Yu can now have what it takes to own a Cursed Weapon, and will notify Guren about his improvement.

Meanwhile, Ferid (still alive) informs to someone with blond hair about Yu and his affiliation with the JIDA. This person then points his sword towards him, threatening Ferid not to do anything with Yu. Mikaela Hyakuya is still alive...

Differences with the Manga

 * The scene where Yuji attempted to trespass into the Forbidden Chamber was not shown in the manga.
 * The scene where Yamanaka and his friend ask for help was set on one of the school's floors' hallways; in the manga, it was set on the rooftop.
 * The scene where Yuu was confronting the demon in the Forbidden Chamber was set in the Hyakuyas' old home in the vampire world, particularly when they were having dinner (in his mind's space). In the manga, it was simply set in a blank, narrow space.
