Yui Komori (小森 ユイ Komori Yui) is the heroine of Diabolik Lovers. After her father moved abroad, she is forced to live in a mansion with six mysterious vampires.
Her outward appearance looks rather girly. She has wavy platinum blonde hair that falls down to her shoulders with her bangs parted in the center and a pretty pink flower hairclip pinned on the left side of her head. Her eyes are a light glistening sherbet pink color.
In the first two games, Haunted Dark Bridal and MORE BLOOD, Yui wears a pink top with sleeves that fall off her shoulders. It is decorated with black straps and a black cross-stitched decoration with black ribbons at the end. She wears it with brown shorts and brown boots. She also wears a gold heart shaped necklace to accompany her looks.
In the third game, VANDEAD CARNIVAL, Yui wears a blue jacket over a white shirt with a brown bow on the front (the collar of the shirt shows above the jacket). She wears it with a beige skirt, black tights and brown shoes. She still wears the same necklace and flower clip with this outfit.
In the fourth game, DARK FATE, Yui wears a white loose fitting blouse with a black and dark pink drawstring top underneath. She wears it with high waisted dark blue shorts with gold buttons, white ankle socks and black shoes with straps that go above her ankles. She still wears the same necklace and flower clip with this outfit.
In the upcoming game LUNATIC PARADE, Yui wears a green gym jacket (the sleeves of the upper arm of the jacket is decorated with a white straight-stitched decoration with white ribbons at the end) over a pale yellow thigh-length dress which is decorated with white ruffles. She wears black thigh socks and brown shoes with straps that go across her foot. She still wears the same flower clip with this outfit, but without the necklace.
Her school uniform consists of the black school blazer with a black deep V-neck vest over a white button-up dress shirt with frills near the neckline. She has a white bow showing through the V of the vest and wears a red bow tied to her neck above the white bow. The bottom is the black uniform skirt that ends above her knees with a white petticoat underneath. She wears it with black knee socks and brown dress shoes.
Yui has a cheerful and optimistic personality, but is somewhat naive as well. She can be oblivious to many things and doesn't catch onto them so easily, as well as having trouble in making decisions in certain cases. Yui seems to be very determined and strong-willed in the worst scenarios and doesn't mind any mean comments thrown her way by any of the vampires. Despite such situations, she usually responds to all the brothers with kindness. As she goes through the game, she slowly starts to become a masochist. Yui is also a strong believer of God. At first, she does not believe in the existence of vampires but eventually comes to accept them.
After Laito pushed Cordelia from the balcony, Richter, the Sakamaki brothers' uncle and Cordelia's secret lover, found her dying. She asked him to cut out her heart and implant it into another body. He did as she asked and implanted it into Yui, a abandoned child who had the ideal body for Cordelia's heart. He then handed Yui to vampire hunter Seiji Komori, to avoid "Cordelia" from being taken away by his brother, Karlheinz. Seiji, who was also a priest, owned a church and raised Yui since then as his daughter. Seiji never told Yui he was not her biological father and was told that her mother had died when she was a child.
Because Cordelia was the daughter of the Demon King, her blood had a power flowing within it. Since her heart is inside of Yui, Yui is a power blood bank for the vampires. All the brothers note that Yui's blood is of the "finest quality." In addition, her chest will hurt when "Cordelia" reacts to something.
When she was 17 her father told her he was moving abroad for work and she was being sent to Japan. The brothers tell her she was given up as a sacrifice.
- In Episode 1, she finds out that she was adopted.
- She doesn't know how to swim.
- She is afraid of thunder.
- She wears frilly blue undergarments and a pink bikini.
- She doesn't know anything about her birth parents.
- In one of the Kanato endings in Haunted Dark Bridal, Yui is transformed into a vampire by Kanato.
- In one of the Subaru endings, it is only implied that Yui turned into a vampire.
- Due to mistranslation by fansubbers, they translated Chichinashi (Breastless) as Pancake.
- Yui is the first person who has survived the awakening.
- As shown in episode 11, it is possible that the room Yui was given to stay in in the Sakamaki Mansion was the room bearing the balcony in which Cordelia was thrown from by Laito.
- In the manga and game MORE BLOOD, her father, Seiji tries to kill her when he catches a certain scent, which prompts him to believe Yui is dead and a vampire is wearing her dead skin.
