Yūichirō Hyakuya

Yūichirō Hyakuya 「百夜 優一郎, Hyakuya Yūichirō」 is a member of Japanese Imperial Demon Army's Demon Moon Squad and is the main protagonist of the Owari no Seraph series.

Appearance
Yuichiro Hyakuya has medium length dark hair which can be considered quite messy. He also possesses sharp green eyes which fall under his thick eyebrows, His eyes are large compared to most other male characters in the series. He is usually shown wearing a typical Japanese school uniform with a white sleeved T-shirt beneath.

After joining the Imperial Demon Army, he takes on their uniform consisting of a black jacket with light green details. Dark gray trousers and black boots which go underneath his trouser leggings. Yuichiro keeps his sheath on the left side of his hip. Sometimes he can be seen wearing the Japanese Imperial Demon Army hat.

Personality
He is brave, fearless and somewhat reckless, as evidenced when he defeated one of the four Horsemen of the Apocalypse while ignoring orders which is noted not to be the first time. He is a very narrow minded person, whose goal is to annihilate all of the vampires because of what they did to his "family"; overcoming any type of challenge in order to accomplish it.

Despite this he has a soft spot and worries about his friends first and his goals second. Some (mostly Vampires) consider his personality as 'cute' like Felid Bathory. Also he empathises with others who put their family first, as seen when a civilian girl gave them false information as she was threatened by a Vampire that they would kill her parents. After finding out about this, he told the girl that she did the right thing to save her family. After recovering from his coma, Yuichiro has grown more mature, as quoted from Shinoa.

It is later revealed that his goal, rather than revenge, is to protect his new friends and family, in order to avoid a repeat of past events.

History
In 2012, Yūichirō's father tried to kill him. While his mother, spread a rumor that he was the son of a demon. Then she lost her mind and killed herself. Which lead to him being sent to the Hyakuya Orphanage Christmas day. There he was introduced to Michaela and the other orphans. Seeing as the two 8 year olds were the eldest Michaela wanted them to be friends. However, Yūichirō was very distant towards Michaela. Michaela made it very clear he was the leader, so he punched Yūichirō. Afterwards, he told Yūichirō that he used to be alone like him, but now he had a big family. And from that then on, he had one too. Yūichirō proceded to tell Michaela of his incidents that lead to his being there. Then Michaela told him with a smile that he was abused by his parents, and then he was dropped out of a car and taken in by the orphanage. The other children told him of their stories. Michaela then told Yūichirō that they weren't lonely because that day was the day their brother Yuu joined them. During the meeting the director suddenly began to bleed from her nose and mouth, and fell to the ground.

Then while outside they saw as the city was engulfed in flames. They had been attacked by the vampires lead by Kururu Tepes. For the next four years they lived their lives as livestock for the vampires.

After Michaela gets possession of a map of the underground, both of them decide to escape the place with the rest of the chidren of the orphanage. However it is revealed that is was all a plan of Felid Bathory, one the Seven Founder, and the atempt to escape is frustrated leading to death of all the family except for him. After getting to the outside world he is found by Glen Ichinose, a captain of the Japanese Imperial Demon Army. In order to take revenge for his family, he decides to join the Japanese Imperial Demon Army to gain the power he needs.

Sometime after escaping he was experimented on and was created into a being that is not human by Glen and the Army.
