Juri's Game Sprite

Juri has straight black hair that reaches below to her waist. Her eyes are a dark grey color.

She usually wears boyish clothes because she is a bit of a tomboy. She does sometimes wears outfits that are a bit more feminine looking though not as often.

In the first two games, Haunted Dark Bridal and MORE,BLOOD, she wears two different outfits. The first one consists greyish white jacket with a black hoodie underneath and a sleeveless green top with a black ring around the collar. She pairs it with black jeans and sneakers. Her other outfit consists a white vest with a red hoodie shirt underneath. She wears the black pants and sneakers with this outfit too. With both outfits, she wears black semi fingerless gloves.

In the third game, VANDEAD CARNIVAL, she wears a beige white-striped dress with purplish lines around the bottom and top. The bottom of the dress is cut in the middle in an M shape which shows off some white ruffles. She wears a white mid neck shirt underneath. Over that, she wears a short-sleeve blue cardigan which is open and ties in the middle; it has two rows of gold buttons outlining the border of the opening. She wears this with black pantyhose and black Mary Jane's with bows on the backs of the straps.

In the fourth game, DARK FATE, her outfit consists of a short dark green jacket with a long sleeve magenta shirt over a black and white striped shirt. She wears this with dark blue pants and sneakers.

In the fifth game, LUNATIC PARADE, she wears a navy blue dress with a yellow belt and grey coat with a sunflower brooch and black crop high-heel boots.

Juri’s school uniform consists of a grey button-up sweater over the black school blazer with a black dress shirt underneath. She wears a red bow tied to her neck. She wears a somewhat shorter version of the black uniform skirt. She wears it with black tights and black dress shoes. When she doesn't wear the sweater, she switches to a white dress shirt and red tie.

When she goes out hunting, she wears a black collar dress with a blue tie and belt along with a blue denim jacket.


Being from a very prominent Japanese noble family, Juri is a calm, reserved young woman who is very mature. Despite this, she has a bit of tomboyish personality as she is quite athletic and prefers to train and play sports.

She is very observant and intelligent, thinking in a rational matter most of the time.

While being a gifted hunter, Juri is very modest about her abilities and knows not to underestimate her opponent or overestimate her own abilities.

Despite being a hunter, she knows that not all supernatural creatures are evil and only hates/hunts the ones that harm humans.

Whenever she talks to any of the Sakamaki's or any vampires, she sometimes responds in a deadpan manner with a hint of sarcasm. She uses veiled insults or threats if they get on her nerves (especially if it concerns Yui).


Juri is the daughter and second child of Haruto Sumeragi and Erika Sumeragi. She has an older brother named Yūya. Her father was one of the sons of the previous head of the Sumeragi family which is one of the oldest families in Japan alongside a sister clan.

Her family, unbeknownst to the people of Japan, are hunters (they hunt supernatural creatures that cause problems; they also investigate cases that involve the supernatural). She was trained from a young age to be a hunter alongside her brother.

One thing unique about her family is their blood. Some of the supernatural creatures they’ve encountered, namely vampires, have noted something different about their blood. Members of the family have noticed the special abilities that the blood gives them.


Yui Komori

Juri is very protective of Yui and has made it very clear to the vampire brothers that she will hurt them if they do anything to her (Yui).

Ryō Hīragi

She first saw Ryō when she started attending Ryoutei Academy as he was in the same class as her. He approached her and asked to talk to her in private. Ryō told her that he could tell that she was a hunter and Juri was impressed. He asked why she was here and she told him about the situation. He told her that he would become her ally/friend and help her protect Yui. Juri was mildly stunned as she didn't expect that answer but she was glad she found someone like him here.

Ayato Sakamaki

Since they both are skilled in sports, Juri enjoys challenging him.

Subaru Sakamaki

After Subaru tried to help them escape, Juri grew to respect him a bit.


Being a hunter, Juri has been extensively trained in the art of killing supernatural beings such as demons, vampires, etc. and has several abilities that have been developed from that. She trains a lot to maintain and further these.


She has increased physical strength which is on par with some demons and most vampires. It is purely metaphysical as her body mass did not change.


Juri possesses great speed and reflexes.

Her intensified speed, agility, reflexes, and endurance makes her somewhat faster than some vampires, demons or any other supernatural creature. She is able to stop supernatural species in their tracks and run miles in a couple of minutes. Her reflexes are also heightened.

Juri also has superhuman stamina, flexibility and dexterity similar to a lot of vampires, demons. She can move, jump very high, flip, climb and run incredibly fast without much difficulty or exhaustion.

Resilience and Healing

Juri’s extensive training allowed her to handle more trauma than most humans, without much discomfort or injury.

Because of her blood, Juri can recover/heal/regenerate from any injury much quicker and more effectively than some supernatural creatures and humans.


Juri has a far more enhanced sense of hearing, sight and smell that far exceeds normal human which came from harsh training.

This also gave her a heightened awareness of her surroundings. This heightened awareness allowed her to know the position of an attacker and fight them without relying on her sight as she was told that sometimes our eyes can be deceived.

Other Abilities

As part of her training, Juri had to be skilled in many martial arts including kenjutsu, ninjutsu, and aikido.

She was also trained in onmyōdō and is a skilled onmyōji.
