Angel

The Angel is a character in the Jujutsu Kaisen series. She is a jujutsu sorcerer from a thousand years ago who was incarnated by Kenjaku for the Culling Game in Hana Kurusu's body. Instead of suppressing Hana's consciousness like most incarnated sorcerers, the Angel lives symbiotically in her body.

Appearance
Angel's true appearance is unknown, as she is incarnated within Hana's body. However, Hana's manifested halo and pair of wings may be parts of Angel's true form.

Personality
Angel appears to be a well-mannered and straightforward individual with the best intentions for the world. Describing her creed as that of obeying the laws of "god", Angel only accepted Kenjaku's offer to incarnate into the Culling Game as his actions would cause destruction on an unprecendented level and was against her creed. Rather than dominating over Hana's body, Angel willingly chose to co-exist with her and was quite close to her, even knowing a few sensitive secrets about her past. She demonstrated some light-heartedness by teasing Hana with the knowledge, although respected her privacy when she refused to let Megumi know just yet.

She was quite willing to associate herself with the sorcerers who came into the Culling Game with the intention to put a stop to it, although she was business-minded enough to be willing to ask for Sukuna's death first before fulfilling what they hoped from her. However, after Hana's body was rendered unable to fight, Angel proved reasonable as she was willing to understand Yuji's reasoning for not telling her about his predicament and chose to free Satoru Gojo so he would be able to kill Sukuna for her.

Perfect Preparation Arc
At some point, during the early stages of the Culling Game, Angel, inside Hana's body, was seen floating upside-down in the skies over Tokyo.

Culling Game Arc
When Hana is questioned about Angel, Angel reveals that they have a symbiotic relation of host and vessel and reveals her goals to participate in the Culling Game, with her agreeing to unseal Gojo after Sukuna's defeat. However Sukuna eventually takes over Megumi's body and despite the Angel's best effort, almost subduing Sukuna, Hana succumbed to Sukuna's manipulation and her body is critically wounded.

Hana was saved by Rin Amai and possibly by Fumihiko Takaba, and later healed by Yuta and Shoko. No longer able to fight, Angel agrees to unseal Gojo and Hana then used Jacob's ladder to unseal Gojo.

Abilities and Powers
Flight: While possessing Hana, Angel granted her the ability to levitate herself and fly.

Trivia

 * "Jacob's Ladder" (Hebrew: סֻלָּם יַעֲקֹב) is a ladder to heaven seen by the biblical Patriarch Jacob in a dream (Genesis 28:10–19). The term may also refer to so-called crepuscular rays — an optical phenomenon whereby twilight sunbeams, shining through breaks within high clouds, illuminate dust and/or haze in the air.
 * The given reading of the kanji Yakobu matches the katakana rendering of the biblical name Jacob (ヤコブ).
