Robby Yarge, a man who comes from wealth but has little luck in life, has a chance encounter with Hatchi Kita, a brilliant young man who is tired of the predictability of his life, and the two begin an adventure toward the world of Isekandar.

The trio stops off on the planet Odwarla, an ocean planet inhabited by merfolk for lunch. When Hatchi is reluctant to use his Smartbracelet, he and Ikku end up having to work off the cost of their meal, while Robby gets food poisoning.

When Robby and Hatchi reach Haccone, they are unable to pass the checkpoint because they lack travel permits. While contemplate their next move, they visit the planet below and enjoy the hot springs, where they learn of a possible solution.

Robby and Hatchi visit Hamama II, home of the Great Eel Festival. Little do they know that Yang and his gang have tracked them there, where they are also enjoying the festivities, as Yang is affected by the eels' legendary powers of virility!
