A character with a pure and innocent nature, she is tasked with making the angels in Heaven happy. She is among the more moderate of the angels, and because of this, when she learns about the exterminations led by Sera, she strongly protests that the Exorcists are doing something wrong. She is a key angel who agrees with Charlie's ideals, and while she may not fall, she is likely to remain an ally helping Charlie from Heaven. Also, while hanging out with Charlie's group, she picked up the habit of saying "Holy Shit!" despite being an angel.

However, Sir Pentious comforts her by saying that all living things can start over even if they make mistakes; encouraged by this, she prepares the army for the declaration of war and attacks flying toward Heaven, but leaves hope to Emily, telling her to try for peace. Later, when Emily is injured by Vox's weapon, she quickly dispatches Lute and Abel. Finally, she empowers Sir Pentious's transmission to reveal his redeemed presence in Heaven to those in Hell, proving that salvation is real. Once the situation settles, she flies to Hell immediately, and despite her own serious injury of a torn wing, she breaks down in tears and hugs Emily, who is smiling brightly before her after performing such a miracle.
