Luna and Leo are twin on Yu-gi-oh 5ds and in my story.

Yugi babysits baby Jaden, baby Syrus, Baby Jesse, little Zane, baby Chazz, baby Alexis, and little Atticus in the first 2 chapters.

Years later when they are teenagers at the duel academy, they don't remember each other, but Syrus remembers Jaden, and Jaden's sister Mirabelle, and Syrus has a gigantic crush on Jaden.

also some one is a vampire.

Guess who.
