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.
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 parent, Yuu. After finding out about this, he told the girl that she did the right thing to save her family.
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.
He was abandoned by his parents since he was a child and he ended up at Hyakuya Orphanage. Since then, the kids of this orphanage were his only family. A bit after while he was still a child, the vampires took him and the rest of the orphanage to their city to become 'livestock'. 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 attempt 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.
