Arc 6The Ruins and the Rune Insects
Ian fought Ging inside his Game Space, then returned to Sharku Manor and drew Milluki and Illumi closer to him. When Rune Insects emerged from the Gugurian Ruins and threatened the country, Ian agreed to help Netero and arrived at the site.
- Ging trapped Chrollo, Uvogin, and Nobunaga before Ian returned and challenged him over the Dark Sonata.
- Ian and Ging fought, then Ging pulled them into his Game Space, where Ian cleared several stages until Ging ended the game after seven hours.
- Ian gave Ging the Dark Sonata, warned that he would visit the nobles Ryuk had named, and learned that Netero was gathering Hunters to investigate the ruins.
- Ian welcomed Milluki as his little brother, gave the group Take-copters, and used magical items to encourage Milluki to train.
- Kannari Rin led the Exorcism Team into the Gugurian Ruins, where monsters infected several members with spreading black runes.
- Ging investigated the cave and concluded that the black runes spread through Nen, while Malice Crystals disrupted Hunters' Nen.
- After Kannari Rin demanded his help and Ian joked about needing a spaceship, Netero called to explain the threat and Ian agreed to assist him.
- Ian used the Anywhere Door to reach the ruins, turned away the Exorcism Team's weapons with telekinesis, and urged Kannari Rin to hurry.
