Setsuko/Rukina

**Setsuko** (Japanese: **節子**, *Setsuko*) is the Shinigami who is the embodiment of what Callisto's aunt taught her what 'love' is. **Rukina** (Japanese: **ルキナ**, *Rukina*) is the alias that Callisto gave her whenever she is brought into conversation.

## Appearance

Setsuko has the appearance of a preteen girl, and is considered to be extremely pretty, even by vampire standards.

She has calf-length rosy pink hair, partially done up into two pigtails by black hairpieces that resemble bat wings. The black headdress is connected by a black headband, and she also has what appear to be short black horns at either temple. She has large, sharp, slightly slanted eyes that are red, along with fangs and pointed ears.

She wears a short black, frilly style dress with a layer of white ruffles over black ruffles of the skirt. The top has a raindrop shape opening between her breasts, and the straps of the top cross before reaching her neck on either side. The top has an open back with two x-shaped crossing stitches tightening it at her waist. A strip of pink goes down either side at the front of her top and ends at bows above her ruffles. Five golden buttons are distributed evenly going down the top on either side between the pink strips.

She has a white collar of lace parted in the center of her neck that reaches over her collar bones. It is bound by a pink ribbon with a large bow on the right side of her neck. It has a golden oval decoration in the center and a pair of ribbons trailing from it that reach her hips.

She wears detached, loose black sleeves that are puffed up under her shoulders run past her hands, becoming wider toward the end. It has two gold buttons at the cuff. A black ribbon is tied into a bow at the top outermost sides of these sleeves, and its tails reach the length of the sleeves. White lace frills decorate the tops of the sleeves, and longer white frills hang out under the sleeves. The white also peeks out in a slit at the puffy part of the sleeves under either ribbon.

Under these sleeves, she wears a pair of black gloves that are tighter against her skin and reach her knuckles. Each one has a pair of pink stripes running down from her knuckles to the end of the glove. They can only be seen when the loose sleeves over them are slid back.

She wears tall black boots that are initially folded below her knees, but they become unfolded after she attacks Keiko. After unfolding, they reach mid-thigh and have a slit down to either knee. They have tall golden stilettos.

On certain occasions, she may wear a black cloak underneath her skirt. It runs from her waist down to her ankles and is split down the center. The inner lining is pink.

## Personality

Outwardly, Setsuko appears to be a kind girl who enjoys spending time with her friend Keiko. Apparently, Setsuko is somewhat of an idol for Callisto's classmates and admired by the people around her, always being friendly and knowing what to do in any situation. Keiko reveals that Setsuko has many stalkers. She is also popular at her school and appears to be well-educated and practical.

However, it is a façade and in reality Setsuko is a manipulator. She is willing to lie, cheat and even kill if that means that she'll get what she wants which is being able to stay with Callisto. Setsuko snaps when she sees someone as a threat to Callisto or her sugar happiness with her, such as Tetsurō and Taketora, which she refrained from bashing his head in with a crowbar. Although she does understand that killing would reduce her chance of being with Callisto. She usually plans things ahead and uses social manipulation to get her way rather than violence.

Setsuko did seem to show remorse when she attempted to get rid of Keiko. She seemed to object to killing her friend. Setsuko uses Callisto's aunt as an excuse for her behavior whenever she has self-doubt or feels guilty. This is the only way she can accept the kind of a person she became.

Many of her behavioral symptoms are tied to the Yandere trope for her and Callisto to live in and spend their days together forever, away from the "corrupted and filthy" outside world.

## Relationship(s)

### The First To See Her

Callisto is Setsuko's sugar love. She tries keep Callisto shut in their "castle" and locks the door to prevent Callisto from going out and to keep her safe from harm. She looks at her love for Callisto to be sweet and genuine, unlike the bitter feeling she had only experienced prior. Setsuko loves Callisto with all her heart. Callisto doesn't like Setsuko but she wouldn't want her to get hurt either. Setsuko also tries to make Callisto happy by, for example, bringing her different types of cake.

Although she soon diminished at the end, when she learned "true love" just before her death, died by protecting Callisto, saying "I want Callisto to live."
