About: When Sidriel was very young he lost his brother, who was taken into another dimension. Making it his goal to find his brother, he started at the recruiters' school to become a Hero recruiter and be able to jump through other dimensions with a Were-Bunny partner. That partner was Bunny, whom he fell head over heels for. Out of fear of losing someone else dear to him, he became way too attached to Bunny to the point of extreme jealousy, which is why Bunny ultimately put an end to their friendship.
Sidriel has blue hair rather than brown like Seiya, and his red shirt is similarly blue while his silver armor is gold instead. Seiya's sister disappeared mysteriously, so is Sidriel but with his brother instead. This leads to them to enter training and become strong, hoping to find them. But while Seiya is a Saint, Sidriel became a Hero Recruiter. His possessive personality is likely derived from Ophiuchus Shaina, who fell in love with Seiya after seeing her face, so she's pursuing him a lot.
