Things are looking tense until Elenoir's former ruler, Virion, has him released. Arthur is then invited to the kingdom's castle. But the pain in his mana core seems to be getting worse...

After being informed of a way to let Reynolds and Alice know about his survival, Arthur joins Virion and they head to a witch's house. Using special sorcery, he is able to see his parents.
