Trine Halden (トリイネ・ハルデン, Torīne Haruden) is terrorist who in a deal with the Free Terrorists kidnapped La Folia and demanded for the release of 11 political prisoners serving life sentences from Aldegyr Kingdom in exchange for her. However, Aldegyr Kingdom did not comply to her demand, so she then hijacked Bifrost and used it to fly to the signing ceremony of Aldegyr Kingdom and the Warlord's Dominion to kill Dimitrie to cause a war between the two countries.
Kingdom of the ValkyrjaEdit
Trine being a beastman of the Civet lineage can use pheromones through licking a person to control that person, even a vampire like how she did to Kojou.
