One of the secondary characters of Eternal Storm and subsequent arcs.

Bio:
Yousef is an only child of a well-to-do couple. He is a longtime friend of Nasim's who became her bodyguard when she went into training as a Key Guardian.
Yousef is excessively protective of Nasim and also extremely bossy and rigid. The only people he truly respects outside of his family are Nasim and her mother, Lady Salha.

Relationships with other OCs:
Nasim - His childhood friend and one of the few people who has his respect.
Takeshi - Though he calls himself a leader, he's very soft and makes sentimental decisions.
Shiori - A child who has no business calling herself a Keyholder.
Atsuko - He dislikes her more than he dislikes Shiori because she's disrespectful to Nasim.
Toshirou - On the same level as Shiori -- he's a child, and he's incompetent.
Sora - Doesn't trust him AT ALL.
Taki (Kobayashi) - Even younger and more inept than the other children. He barely acknowledges her existence, but blames her involvement on Takeshi.
Takumi - He doesn't trust him because he's associated with the Key-Seekers, though he can appreciate that he's willing to make the tough decisions.
