Chrono Phantasma
In Ikaruga, Carl discovered that both Ragna and Kokonoe were nearby, leading him to pursue them respectively for the Azure Grimoire and answers to his sister's condition.[5] Soon enough, he arrived in the 8th Hierarchical City of Wadatsumi, where he met Bang and Platinum the Trinity. Platinum made an inappropriate comment about Ada's condition, leading Carl's anger to explode in an attack towards Luna, and he rejected Bang's offer to show him the city. He left them both, explaining he was destined for the 6th Hierarchical City of Yabiko. On the way there, in the 7th Hierarchical City of Kazamotsu, Celica A. Mercury happened upon him and repeatedly called out to Nirvana. Irritated, he attempted to battle her but was interrupted by Hakumen; he lost to the hero and continued onward to search for Relius.[6]
Following Nirvana's guidance, Carl found himself face-to-face with Relius and Ignis. They talked about Litchi and her decision to join the NOL, and finding himself so enraged with Relius' personality, Carl attacked as soon as possible, but was unable to even scratch the man. Relius left after promising that he would rebuild Ada, should the time come. After leaving the area, Amane Nishiki brashly approached him and begged him to join his traveling troupe. Carl gave him little chance and left as soon as the opportunity arose, in no joking mood after his meeting with his father.[7]
Near Kushinada's Lynchpin, Carl deflected a blow from Ragna that had been directed towards Relius. Litchi and Bang begged him to not join the fray, but he ignored them in pursuit of Ada's cure. Nirvana and Ignis' tag-team prevented the opposition from advancing, but the two were soon split up with Carl taking up arms against Izayoi.[8] After losing, Carl protected Relius and evacuated them, insistent on him fulfilling his promise to save Ada from her mechanical condition. Litchi aided him in taking his father out of the area.[9]
