Since Serena has always tried to prove herself to the Professor do you think you can do something where little Serena goes and finds little Yuri cause he's like the best duelist at the academia and they meet and something cute happens.

Yuya having the dubious "honor" of being Zarc's favorite is somehow hilarious to me? I'm just imagining the bracelet girls going to Ray and asking, "Hey, who's your favorite reincarnation?" and Ray responds, "I don't have a favorite. You're all equally special to me." Meanwhile, the Yu boys go ask Zarc, "Hey who's-" and Zarc, not looking up from what's he's doing, replies, "Yuya."
