Rei Sagara

Rei Sagara (相楽 玲 Sagara Rei) is the manager of the famous Sena family who was found and brought to the family by Seiya Sena at the age of 18 and the husband of Shougo Sena.

Appearance
Rei is of medium-short height with short dark gray hair (although it looks green and sometimes blue in lighting) that has chin-length bangs going on either side with his forehead showing and golden-brown eyes.

He is mostly seen wearing a suit and round-shaped glasses, despite having perfect vision. He only wears glasses since, without them, he gains a lot more attention from those around him that he wears them in order to divert unwanted attention.

Personality
Rei is shown to have a serious and no-nonsense attitude, especially in his job as a manager. He is a hard worker and is the main care-taker of Izumi Sena, seeing him as his own son. Rei is somewhat of a Deadpan Snarker, wearing a constant poker face and bluntly telling it how it is, often refusing to sugar coat anything. However, he is considerably patient with Izumi and Shougo Sena (the latter whom he is shown to have a small measure of control over) unless something causes him to finally snap in anger. His cool and professional exterior can sometimes make people think he doesn't care, when in reality he does quite a bit.

History
Rei's mother worked as a prostitute in order to support the two of them since he was a child. He never knew who his father was, with it only being stated that his mother had been someone's mistress and he had not be in contact with Rei's biological father since the time of his birth, in which Rei could only wonder who his father possibly was.

Because she raised Rei using money she earned as a prostitute and the nature of her job, his mother was never around Rei much as he grew up; often leaving him alone from a young age onward. It was because of this that Rei never developed any sort of genuine attachment to his mother, eventually no longer caring for her during his elementary school years. When she died in an accident a few days before Christmas when he was 18, Rei could only feel sadness that he lost the only remainder of family he had left in his life.

Because he was left to fend for himself, Rei began picking fights early on in his life with anyone who crossed his path starting in his middle school years. He soon managed to teach himself in becoming an excellent fighter. While he managed to make it to high school, his behavior only worsened and he became involved in a fair number of dirty dealings. In the Back Stage manga, he reveals that he did "every dirty deed short of murder".

Despite his lack of studying, he showed great learning ability and intelligence. His teachers had even offered to make recommendations for him so that he could get into a good university. Despite this, he was forced to give up his college goals due to a lack of funds. Feeling that his future had been snatched away by his family situation, he became even more violent and bitter. By the time his mother died, he felt that he had officially hit rock bottom.

However, Seiya Sena came along and literally found him in the streets before he gave him a home, an education and an eventual job as his personal assistant. Soon enough, Rei became the manager of SenaPro and he made it his goal to look after his new family and their careers.
