Who is the criminal who intends to unleash war between the world of humans and the Dark Territory? The heroes of the Underworld, Kirito and Asuna, expose the enemy! The mountain goblin Mialu is suspected of murdering the cleaner Yadzen, but this simply could not have happened in the Underworld, where the inhabitants are bound by the Code of Prohibitions and the law of the strong. Trying to make sense of what happened, Kirito seeks help from the commander of the dark world army, Iskan, but the supposed criminal, a mysterious man in a black cloak, slips away from them. When the investigation reaches a dead end, Asuna visits the tavern where the murder occurred, and the spell of looking into the past reveals incredible things to her... Meanwhile, dark clouds are gathering over the knight apprentices Ronye and Tise! Conclusion of the "Moon Cradle" cycle!
