When I was making fanarts of Jillas, I also decided to make fanart of Elena and Palou, Elena's son, from The Slayers Try.
Sadly they only appeared in one episode and Jillas decided to continue his vengeance against the Slayers instead of having a happy life with Elena and Palou.

In my headcanon, Jillas decides to abandon his grudge towards the Slayers and stay with Elena and Palou. Eventually, Jillas confesses his love to Elena and becomes Palou's father.
