Naoe and Elfuda get ready to go to the sauna! Time to sweat off some pounds with a boosted metabolism! But rumor has it, an ogre is a regular at the sauna...

Elfuda shows Naoe the entrance to the alternate dimension where she entered his world. Then it’s back to running, but too much exertion can lead to injury!

While training at the park, Naoe and his friends encounter Kobo, who is snatching sweets from the local children! Kobo is worried about weight gain from eating too much candy.

Elfuda receives a coupon for a year’s supply of free fries at a hamburger shop! However, it’s a trap!

Naoe is worried that the people of the otherworld are not losing weight, so he takes his group to a hot yoga studio.

Kuroeda creates a suspicious potion using black magic and plans to have Elufuda drink it as an experiment.

Naoe is worried about Ooeda's harsh regimen is taking its toll on Elfuda. He finally decides to intervene.

The group changes into swimsuits for the beach.
