Twenty-two-year-old Wang Chen receives a mysterious package. Inside the box is a diorama of the Pokemon world, where Groudon and Kyogre are fighting. To keep the world from being destroyed, Wang Chen lifts Kyogre out and dumps it in his kitchen to wash dishes...
After that, Pokemon are regularly "invited" to Wang Chen's home to lend a hand: Kyogre uses "Rain Dance" to wash the dishes, Groudon uses "Sunlight" to dry the clothes, and Zapdos uses "Thunder" to zap mosquitoes.
The girls, including May, Cynthia, and Marnie, are also utterly devoted to Wang Chen:
Help May become the Hoenn Champion, affection +50%.
Guide Cynthia in solving the mysteries of ancient ruins, affection +50%.
Help Marnie revive her hometown's economy, affection +50%.
At the same time, Wang Chen discovers that there are people from other worlds inside the box, too: MyGO? Ino Yamanaka? Marie Rose? How did they get here?
...A few years later, Wang Chen looks at the many leading companies under his control and all the girls at his side, and nods in satisfaction...
(PS: This novel is easy to follow. Even readers who don't know Pokemon can enjoy it as an urban story! The battles are Double Battles and a little hardcore, so battle fans are welcome to check them out!)
