One spring, a teenage boy suddenly started seeing strange "things" that are apparently invisible to others.

One peaceful afternoon, the Son family and friends are spending the day out on the town shopping in West City. Meanwhile, two strangers enter the city and begin causing havoc, destroying nearly everything in their path. As the Son family is eating, the building they're in is suddenly attacked, as it turns out the two are after Son Goku. When Goku sees that innocent people are being attacked in his name, he becomes furious. Trunks comes to Goku’s aid, and the two lead the artificial humans out of the city. As the battle is moved elsewhere, Goku and Gohan, now dressed in white tuxes, return and land in West City. The two proceed to show clips and highlights from the preceding Dragon Ball and Dragon Ball Z movies. Goku of course doesn't much like being all dressed up, and by the end he powers up to change back into his typical dōgi. Gohan tries to do the same, but isn't powerful enough to get out of his tux. Goku says he’ll get there someday, and Gohan tells everyone to be sure to go see “Extreme Battle!! The Three Great Super Saiyans” in theaters.

After achieving fruitful results in New World Online's previous events, the now famous Maple Tree guild is excited to explore the new floors introduced in game. As if their guild was not already feared enough, each member is motivated to find stronger skills for themselves in order to greatly expand their options in future battles. Not forgetting the importance of networking, the guild also forges amicable relationships with other notable guilds, such as the Kingdom of the Flame Emperor and the Congregation of the Holy Swords. With their eccentric guild master Maple at the forefront, the members of Maple Tree continue to stumble upon creative ways to implement their skills, driving the game developers crazy along the way.
