Sly

Sly is a student at Duel Academy.

Third Arc
Appearing on this second season as one of the many students of the Academy, he also seems to hang around with the twins Leo and Luna as well as with Dexter, Bob and Patty at times. That is seemingly that is more a solitary type, thus for some reason Luna seems to interact more with him than the others.

Thus for some reason Sly shows a high interest of obtaining Yusei Fudo´s, "Stardust Dragon". This is seen when he tries to steal it while helping the others pick up Yusei`s card from the floor.

Also, like the them, Sly was going to be expelled from Duel Academy by a teacher until Yusei challenged the teacher to prevent this.

Deck
The only known card belonging to him is Eccentric Boy.
