Bojji, a prince in a world where kings are ranked by their deeds and skills, is considered unfit to be the next king due to his disabilities. He runs into Kage, a shadow being with whom he can converse, but who also takes advantage of Bojji's kindness.

Kage's tragic childhood following the purge of his people from the Kingdom of Bo is recounted. As the match between Bojji and Daida continues, Bojji's fighting style is denounced as cowardly, and he is instructed by Domas to adopt a more regal style.

King Bosse passes away, naming Bojji as the next king. However, the announcement of the new king does not go as Bojji expects. After being told that Kage has gone on a journey without him, Bojji resolves to go on a journey of his own, to Hiling's dismay.

Kage pleads with Desha's brother Despa to make Bojji powerful enough to be king, and Despa takes Bojji on as an apprentice. After making his assessment, Despa is astounded by how little power Bojji actually has, but refuses to give up on training him.

Bojji, Kage and Despa go out to dinner to celebrate the conclusion of Bojji's training. Kage has misgivings about Bojji's sword until a fight breaks out at dinner, and Bojji has to defend himself. Bojji and Kage must consider what their next step will be.

Leaving Dorshe and Hiling behind to rest, Bojji and Kage lead a party to the underworld entrance to send the magic beasts home. Domas and Hokuro encounter the Order of the Underworld deep underground on their way to recapture the missing criminals.
