jewel brother # 2 - setsu yuuki (dylan of mirmo) - Ruby

Setsu Yuuki /Dylan Yuki (First appearance:ep 001)

Age: 14

A smart and quiet bookworm (an honor student), on whom Katie and Azumi have crushes and is Rima's partner. Although he is silent, cool, calm and reading most of the time, he's willing to help his friends, even if it embarrasses him. It is a bit mysterious who he liked first, Katie or Azumi, since he went out with Katie in the first season of the anime. He is also afraid to eat green peppers. In the near end of season four, when Haruka Moroshita, his childhood friend proposes her strong love for him, he begins to gradually get close to her. When Haruka makes her decision to set Dylan free because she knew that Katie is the one he really loves, she tells Dylan that he should do something or else he will lose the person he wants. After his small argument with Rima, he went home and he looks like his thinking of something very deep. He then decided to call Katie and told her to meet him at the park and asks her if she can bring a watch. At the park he tells Katie about how he feels and finally confesses to her. Gladly, Katie, of course, accepts his proposal. (First appearance: episode 001)
