Han Yu journeyed through the world of Sword Art Online.

He bound to the system and gained skills.

As a gifted and powerful player, single-handedly challenging bosses was a daily occurrence.

He achieved undefeated status in SAO, single-handedly breached the World Tree in ALO, and became a legend among players.

In GGO, he slashed sniper bullets within three meters with his lightsaber, and in Uncharted Wars, he single-handedly held off tens of thousands of Dark Territory troops, becoming a player god.
