Characters from the series are obtained upon completing the quests. Currently, some characters remain unavailable to select but are playable as support characters and may be obtained in future updates.
Quests revolve around the simultaneous mix of story scenes and combat, employing some story scenes prior to the combat phase of the quest. The quests feature varying characters from multiple games in the series while also employing specific storylines and circumstances from particular games within the main story arcs. While in the vein of the speicified game's story, the plot is slightly modified to accommodate characters that were previously absent. Such is exemplified by the addition of the Adlehyde "Ruins Festival" event and the inclusion of its aftermath in the main story.
