Während Chaika und ihre Begleiter mit einer weiteren Heldin jener Truppe, die ihren Vater zu Fall brachte, kämpft, wird Gilettes Truppe befohlen, die Verfolgung fortzusetzen. Vivi hat sich derweil anderen Fragen zu stellen.
During last days of the war, Emperor Arthur Gaz orders one of his official to be charge in charge of a secret project involving Chaika. A month after the events of the Soara, Toru, Akari, Chaika duels with Lady Claudia Dodge, another of the Eight Heroes and her men but Chaika loses to Claudia. Despite this, Claudia allows Chaika and her companions to stay at her estate. Toru and the others learn after the war, Claudia hired out of work soldiers to her vineyard and despite being one of the Heroes, she is willing to give Arthur's heart to Chaika if she and her companions beat her in a duel tomorrow. Taking Claudia's advice, Chaika tries to learn to shorten her incantations to fire her spells faster. Meanwhile, with the Council now taking the Chaika threat more seriously, Konrad orders the Gillette Corps to continue their mission with Nikolai promoted as Captain of the Corps after Alberic's death. Elsewhere, Vivi is confronted by Guy and refuses to believe him when he tells her she is another Chaika albeit one that did not transform completely. Despite being a half-Chaika, Guy believes Vivi can still help in gathering Arthur's remains. The next day, despite being unable to learn short incantations, Chaika insist on beating Claudia fair and square as she, Toru and Akari battle Claudia in their duel.
