Naoe has a last appointment booked for the day; the client's name is Elfuda and she comes from another dimension; now, she needs some help.

Erufuda isn't the only person from another dimension worried about gaining a few pounds; she is shocked to discover Kuroeda, a dark elf, is also stranded in this world.

Naoe and Elfuda prepare to visit the sauna for a metabolism-boosting sweat session, but rumours swirl about a regular ogre patron.

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.

Skeletal remains are found beneath Naoe's bed. They decide to piece together the skeleton, embarking on a quest to solve the mystery surrounding its origin.
