Yuuka, also know by his nickname Yuuka the Surge is a former mage of Lamia Scale and one of Leon's allies during the Garuna Island arc. He served as the the guild anti-mage as his magic could cancel out others.

History
The only history known about his is that his family was a victim of the demon Deliora. It was for this reason he joined up Leon on his quest to beat the demon himself.

Plot
Leon then moves the demon to Garuna Island for a Moon Drip ritual that will unfreeze Deliora. They however run into complications with Team Natsu who are on a unauthorized S-Rank mission, soon coming into confrontation with Leon's group. After Leon order his allies to destroy the village of Team Natsu's clients and fail. Natsu take both Toby and Yukka on in the ruins of the village. Yukka then decided to fight Natsu himself and has the advantage for a bit since Natsu can't use his magic while fighting against Yukka's. However Natsu finds a way around the problem by punching straight into the anti-magic shield. While Natsu can't use his magic in the shield, he has no problem using it out of it. To which he uses his fire magic as a booster on his elbow, giving him the velocity he needs to punch Yukka through the shield and knock him out.

Abilities
Yukki wields an anti-magic known as Surge which he creates energy balls from vibrations that nullify magic. He can also throw these balls as projectiles and create a shield around himself to block attacks. It also harmful to anyone foolhardy enough to punch straight into without magic (as Natsu found out). However while anything within the sphere is nullified, magic can still be use from the outside to help with the object thats inside she sphere.
