Keiko/Reiko

**"If you don't want to die...think!"**

**Keiko** (Japanese: **慶子**, *Keiko*) is the Shinigami who is the embodiment of Callisto's darker side, and her pain. **Reiko** (Japanese: **レイコ**, *Reiko*) is the alias that Callisto gave her whenever she is brought into conversation.

## Appearance

### Middle School

Keiko is described as a beautiful young girl with long ashen hair with short sidelocks, amber eyes and Callisto has commented that her other side was shorter and way a bit more voluptuous than herself. When she was a namanari, Keiko displayed no distinct physical features that showed the demon was in control except for a red glint in her pupils that rarely showed. After her hatred lessened and she left middle school, her eyes became red and grew fangs.

### Human-Like Appearance

She is usually seen with a sailor fuku, which consists of a blouse with red trim around the collar with a grayish blue sailor-style collar which also has red trim and a similarly colored skirt with a belt. The red uniform ribbon which is thinner than normal sailor fuku is attached to the bottom right end of the collar. The school's emblem is located on the right breast. She wears thigh length grayish blue stockings and dark blue dress shoes along with it.

### Demonic Appearance

(By "her" in this, I mean Callisto)

Keiko is described as an adorable, and beautiful young girl with shoulder lengthened ashen hair same as Keiko's, and the large bow on the back of her head is a dark shade of magenta and is at the end of a twisted braid. Callisto describes her as having clear, piercing red eyes that seemed to stare out at the world and skin so pale that it was almost transparent to her blood. On her left arm, she has a black shackle.

She has a black horn on the right side of her head, with a crown of her left. The bleeding heart on her cheek represents her heartbreak. The cracks on her face represent how hurt she's been, the stitches are representing her trying to fix herself.

## Personality

### Namanari

Keiko is in this state for most of the *Callisto Kuroo* fanfic series. The demonic side of her gradually takes more and more time in control of her body and twists her love for Callisto by starting his transgression into demon hood as well. Her need for power to protect and be with Callisto warps into a desire to either rule or destroy the world.

Keiko-Kira laughs often and loves to mock Tetsurō and the other characters existence. She has no sympathy or compassion for anyone and is willing to ruthlessly kill anyone who stands in her path and is even cruel to them. But she her love for Callisto is there but even then, she is not above being cruel and be willing to harm her. Her love is also twisted so that while she will not kill Callisto, she is absolutely delighted when Callisto shows her strength or touches her(Keiko) and wants her to give in to her demon and join her. She is, however, not above showing other dark emotions whenever Callisto is involved, showing cold rage when Callisto coldly said she didn't gain power just to be with her and a strong sense of jealousy towards the guys who love Callisto despite knowing how Callisto would never fall for them as she only loves herself and acts particularly cruelly due to this, along with also showing resentment at even Callisto's other friends, noting that she wants her(Callisto) to kill all of them and actually being bitter when referring to how Callisto wanted to protect both her and them. Along with that, she maintains "contact" with Tetsurō, seeming to indicate she retains her care for her. Since the human and demonic personalities are in flux, they can be seen arguing and fighting for control whenever the Callisto is losing a match.

### As Of Now

Keiko's personalities no longer fluctuate, and she expresses both the haughty playfulness of her demon side and the hopeless love of her human one. She is now consumed by lust for "blood." She also enjoys battles and manipulating others to do her will. Her human personality seems to be about as strong as her demon one, however, which manifested in her showing love for Callisto and care for Tetsurō as well as being much more easily angered and jealous.

## Relationship(s)

### The First To See Her

**Callisto Kuroo**: Out of everyone in the *Callisto Kuroo* novel series, her other self Callisto was the only one who Keiko genuinely loved and cared for. Although, according to Reiko, they were not close. The Author, Akagisa12 explains that Keiko was made and raised with Callisto's hatred and loneliness growing up, but Callisto appears to care a lot about her eight years later. In truth, Keiko worried for Callisto deeply when she was still "human". After Callisto realized the "demons" residing within her body due to her past were slowly consuming her mind with age, Callisto in desperation managed to "create" a "separate" being to remove the "demons" in her and bore two demons in now Keiko's own embodiment to protect herself from becoming a "demon." She was also determined to give Callisto success in mostly everything with her power.

When her demon and human side merged, Keiko retained her love for Callisto as Keiko-Kira and she is delighted whenever Callisto chats with her in her mind. Although not above taking control at times, she mostly allowed Callisto to do whatever she does. She manifests quite often when Callisto mentions her, much to her happiness which she sometimes complements her, though she ignores her. Indeed, Keiko went as far as to comfort Callisto in her demonic form, willingly shouldering the blame of causing the Catastrophe along with her.

**Tetsurō Kuroo**: When they met for the first time as seven-year-olds, Keiko told him she would never fall in love with him as she already had someone. Later on, Keiko was angered by Tetsurō's comments on her obsession with Callisto and in a rage, she remorselessly and violently tried to kill Tetsurō in anger. After splitting away from Setsuko the spirit of Keiko would see that Tetsurō can see her.

**Callisto's Aunt**: She was actually the first person to see Keiko(Setsuko wasn't "born" yet) apart from Callisto. But when she met the Keiko, she wasn't fazed. Instead she was pretty happy. She was fascinated about her, she wanted to know how she was created. She guessed it was because of Callisto's loneliness which she was right. But she also guessed it was because of her hatred for her parents murderers.

## History(WIP)

Keiko was created with Callisto's hatred, which lead to her being born in 1996 with a demon inside of her. Eventually, when Keiko was six years old, Callisto ended up "creating" another "demon." But this one is just created because of her Aunt, the one who corrupted her view on what love is.The following year, the Kuroo's adopted Callisto to be Tetsurō.

Upon meeting Tetsurō for the first time, Keiko tells him she wouldn't care for him as she only has one person she cares for; however, if she openly stated to him that she, Callisto didn't want her, Callisto only created her to not completely keep herself corrupt, and Keiko still wanted to be with Callisto. Hence, she and Tetsurō agreed that he would help her get Callisto to start caring for her.

When Callisto hit puberty, the "demon's" influence became stronger in that she continually blacked out and lose herself to desire. Keiko not wanting Callisto to end up with the a bad fate, Keiko locked the other "demon" away because they didn't have any good intent. Sure, Keiko has bad intent as well, but it's only to keep Callisto. On top of being her "demon," Keiko saw visions of the future and even prophesied who would win Nationals.
