Plot

One day, an eight-year-old girl named Pride Royal Ivy regains memories of her past life and discovers she has been reincarnated in the otome game Our Ray of Light. In-game, Pride is a sadistic and monstrous young girl who grows up to become a callous queen and serves as the final boss, who meets her end at the hands of her younger sister whom she wronged. Realizing this, Pride uses her skills and knowledge of the game to become a compassionate and benevolent ruler. She hopes that by changing her ways, this will lead to a better future for her kingdom and the people around her.

Characters

Pride Royal Ivy (プライド・ロイヤル・アイビー, Puraido Roiyaru Aibī)

Voiced by: Fairouz Ai (Japanese); Karlii Hoch (English)

Pride is the main protagonist, being a person who is incarnated from the real world into the current game world. The original Pride was a monstrously selfish woman who callously abused everyone, being seen as a devil in human form; only to eventually meet her end at the hands of her younger sister. The current Pride uses her memory of the original timeline to save and protect everyone that would have been abused by her; unintentionally causing them and herself to have glimpses of the original timeline. Whenever she makes alterations to the current timeline, the actions of her original self are seemingly imprinted onto others who carry them out in her place. She possesses a "cheat ability" that makes her an incredibly strong fighter.

Stale Royal Ivy (ステイル・ロイヤル・アイビー, Suteiru Roiyaru Aibī)

Voiced by: Maaya Uchida (Japanese); James Marler (English)

Stale is the adopted brother and assistant of Pride and possesses the power of teleportation. The original Pride placed him under a magical contract which forced him to obey her, taking advantage of his inability to read, and then ordered him to murder his birth mother, leading him to swear revenge. The current Pride has treated him with great care and compassion, notably allowing him to communicate with his birth mother, and so earning his loyalty and love. He is frenemies with Arthur.

Tiara Royal Ivy (ティアラ・ロイヤル・アイビー, Tiara Roiyaru Aibī)

Voiced by: Haruka Tomatsu (Japanese); Brittney Karbowski (English)

Tiara is the younger sister of Pride and would have been the protagonist in the original version of the game's events, where she would kill her older sister. In this alternate timeline, she instead has a close relationship with Pride and does not fight.

Voiced by: Junya Enoki (Japanese); Adam Gibbs (English)

Arthur is the son of the Knight Captain Rodrick who possesses the power to improve the vitality of plants. In the original timeline, he watched as his father died in battle while the original Pride mocked the fallen soldiers, leading him to swear vengeance against her to the point of not allowing the original Tiara to get close to him due to her relation to Pride.
