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

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.

The gang unearths a whole person's worth of bones from underneath Naoe's bed! Time to put together a skeleton.
