Rosebank

is a Holy Knight serving King Arthur Pendragon of Camelot.

Demon Realm arc
Rosebank is part of the group led by Mortlach that is sent to deal with the Four Knights of Apocalypse.

Following them through the hidden entrance to the Demon Realm, they are all thrown into the void by the relic-portal's filtration system. The Holy Knights save themselves by summoning an Arakdo. However, Gawain, who discovers their presence, uses a spell to switch places with Rosebank and infiltrate the enemy, leaving Rosebank to fall to her death.

Rosebank barely survives the fall, being left at the mercy of the Demon Realm. However, Percival, who was searching for the lost Dragon Handle, meets Rosebank by chance and decides to use his power to heal her despite being an enemy. Rosebank then finds the Dragon Handle and takes it away before Percival could stop her.

Rosebank manages to find her companions who had discovered and captured Gawain. However, remembering how Percival saved her life, she tells them nothing about the Dragon Handle.

Six days later, the six knights follow the Knights of the Apocalypse who were marching towards the Behemoth inside an Albion. After both the Chaos Knights' Arakdo and the Albion were destroyed, the latter begin to be affected by the Behemoth's negative energy, until they manage to get Percival to save them using Gawain as a hostage. Percival tells Rosebank that he can't let her die after saving her once and reminds her that she have something to return to him.

When Mortlach challenges Percival to a fight, Rosebank warns Percival not to accept and then tries to convince Mortlach that they can come to an agreement instead of fighting to the death with the one who was able to save her life. However, Mortlach insists that they must fulfill her mission to protect what they love.
