Kuroyukihime (黒雪姫, Kuroyukihime; Literally meaning "Princess Snow Black"; lit. Black Snow Princess) is one of the main characters in the Accel World series. She is the current leader of the Black Legion, Nega Nebulus, and was formerly known as the Black King (黒王, Kuroō), but hid after defeating the former "Red King". Her biggest ambition is to reach level 10 and meet the creator of the Brain Burst game, but to accomplish that goal, she has to defeat five other level 9 users who happen to be "The Six Kings of Pure Color", the leaders of the six most powerful factions in the Brain Burst world.


Kuroyukihime's Anger

Kuroyukihime's Anger.

She is a very calm and patient person, a girl who constantly loves to drink tea, if it is in school or in a restaurant. She is not always that calm and patient as she can sometimes be rude, angry, or even jealous when some girls are starting to flirt with Haruyuki. She is also a girl who is wise with words and can talk manipulatively to another which they see it as annoyance. She is also a smart and clever girl, knowing the details about the "Brain Burst" game, since she was once known as the "Black King". The Brain Burst is not her only knowledge. She also has knowledge about wired connections or anything network related, as she can tell and give information in the smallest details. She even knows the steps of the networks that has been used.

Kuroyukihime thinks highly of herself also as a very intelligent person. At the time that she was called "Black King" she killed the previous "Red King" and also tried to kill the other members of the "The Six Kings of Pure Color" to become level 10 and find out who the creator of the Brain Burst game is. When she doesn't know someone's name, she will address them as "boy" or "girl", as she did with Haruyuki constantly when the two met and afterwards. She seems to be skilled in playing simulation or any types of games, knowing that she defeated Haru in his own game by achieving more points than him, however she later admitted to using Brain Burst to defeat his score in the end[1]. She also loves Haruyuki and their friendship starts to grow more to the point where she is pretending to be his wife. However, even when they show romantic feelings to each other, in the Brain Burst world, they become serious in fighting against others or giving each other information, but will change if someone tries to flirt with Haruyuki[2].


Kuroyukihime is a mysterious and popular student who also happens to be the Student Council Vice-President at Umesato Junior High School. Her Brain Burst Avatar is Black Lotus (ブラック・ロータス, Burakku Rōtasu), which she was a burst linker only when she was 8 years old. She formerly was the "Black King" but was driven into hiding after killing the previous Red King while she tried to defeat all other kings to reach level 10 and meet the person who created the game. She values Haru as more than a subordinate and is often the voice of reason to him when he is willing to go to extremes to protect her. Prior to her hospitalization, she confesses to Haru that she fell in love with him[3].

Kuroyukihime in school clothes.

Holding true to being "the most beautiful girl in school" Kuroyokihime is a very attractive young girl, with a slender figure, large hazel eyes, and long flowing black hair. Her hair usually has two strands of hair extended from the top of her brow, resembling the antenna of a butterfly. When Kuroyukihime was hospitalized, she had her hair in a ponytail. Her wardrobe is usually her school uniform consisting of black tights, a dark green skirt with a brown trim, a navy blue blazer and a light blue bow tie. As she moves to her final year at school, her uniform alters to a red bow tie with all else being the same. It is extremely rare to see Kuroyukihime in casual clothes. It is somehow known that she prefers to wear black colored clothes.

Plot Outline

Return of the Black Snow Princess Arc

Kuroyukihime is first seen in her avatar in the school's network where Haru first notices her appearance. She later meets Haru for the first time after she beat his score in his squash game with a lvl. 166. She then asks him if he would like to accelerate to the next level. She goes on saying if he wanted to, then he is to come to the lounge during lunchtime and then leaves. After Haru appears, Kuroyukihime gives him permission to come sit with her. Kuroyukihime signals Haru to have the seat in front of her. She then pulls out a cable for a Direct Wired Connection between her and Haru surprising everybody in the lounge. Haru is surprised by this and questions her on why she wants to do this, as wired connections are for lovers. However, she continues on while talking through mental communications to keep their conversation private. Kuroyukihime then states that she is sending Haru a program called Brain Burst to his Neuro Linker.

After hearing everything she said, Haru decides to accept the program and starts installing it. As it is installing, Haru asks Kuroyukihime as to what exactly is Brain Burst. She then tells him that she will answer all of his questions only if the program successfully installs. As soon as it has successfully installed into Haru's Neuro Linker, Araya and his gang appear in the lounge since they were looking for him for the food that he was supposed to give. Kuroyukihime interupts into their conversation and tempts Araya into hitting Haru, but before he could, she shouted to Haru to use the Burst Link command to which he did.

After accelerating, Kuroyukihime goes on explaining the details about the Brain Burst program and how acceleration works. Then, she plots a plan to have Araya expelled by telling Haru to let Araya hit him and have it all recorded on the school's camera. They return to normal speed and Haru is struck by Araya and is flown towards Kuroyukihime injuring her as well. Araya and his gang is then taken into custody. Before leaving, she tells Haru to make sure he doesn't turn on his Neuro Linker until tommorrow in order to ensure that he doesn't connect onto the global net.

Haru returns to Kuroyukihime the following day, telling her that he lost his first duel to which she replied that its his fault as she told him not to connect. However, they both accelerate in order for her to fully explain the details on how the duels and avatars work in Brain Burst. When they finished, Megumi and the other students asked what the relationship was between the two. Kuroyukihime simply stated that she was rejected to him to which everyone was shocked. Leaving the school, Kuroyukihime decides that Haru is ready and pushes him outside the school's network. Haru once again fights against Ash Roller where Kuroyukihime is watching everything from the sidelines. After the match is over, she congratulates him, but is interupted by the sudden appearance of Chiyu who has decided to confront her in order to get answers.

Return of the Black Snow Princess (Elements Side Story) Arc

Return of the Black Snow Princess - Takumu met with Kuroyukihime, who accelerated, challenging Takumu to a duel, she confronted him about his intention to quit kendo and eventually uninstall Brain Burst, Kuroyukihime taught Takumu to stop feeling guilty and trust his friends more.

Crimson Storm Princess Arc

Dusk Robber Arc

Dusk Robber (Elements Side Story) Arc

In Okinawa, Kuroyukihime was on her school trip with her friend Megumi. When the two went souvenir shopping for each other, Kuroyukihime was approached by two local Burst Linkers, Ruka Asato and Itosu Mana, who asked her to help their master fight against an enemy that is plaguing their Accel World community. Their discussion caused Kuroyukihime to lose track of time and forget to buy Megumi a present, which upset Megumi. Kuroyukihime apologized to Megumi by telling her that, since she discovered Brain Burst seven years ago, she is the one who kept her tied to the real world. The next day, Kuroyukihime entered the Accelerated World with Ruka and Itosu to meet up with their master, who turned out to be an old acquaintance of Kuroyukihime's, Crimson Kingbolt.

Kuroyukihime was reunited with Crimson Kingbolt, aka "Crikin", a Burst Linker who moved from Tokyo to Okinawa after his parents divorced. They were then surprised by the mysterious threat, revealed to be a Burst Linker named Sulfur Pot, who had the power to tame "enemies". When it is mentioned that Sulfur Pot didn't appear on the challenge list, Kuroyukihime realizes that he's from Tokyo, using a backdoor program to dive into Okinawa. After defeating Sulfur Pot, Crimson Kingbolt then gave Kuroyukihime the Enhanced Armament that Sulfur Pot used to control the enemy, Mystical Reins, figuring she may use it one day. As Kuroyukihime departs Okinawa, Ruka and Mana see her off. Kingbolt then sends her message informing her that the trail on Sulfur Pot has gone cold. Kuroyukihime can then only wonder about the mysterious faction Sulfur Pot belongs to.


Kuroyukihime's virtual character design

Kuroyukihime's virtual character design.

Kuroyukihime is known to have an exquisite, original virtual character design[4]. Her virtual character resembles that of a butterfly, and has been dressed with balled shoes. The overall look is black and while other parts have red or purple. Her avatar also carries an umbrella. This virtual character is the one she commonly uses whenever she has contact with other people and discusses with them about things that are usually happening around school, or she also uses it to demonstrate the world of acceleration, on how they can use it, or on how they can't use it. This avatar is known as black swallowtail butterfly.

Black Lotus

Black Lotus

The Black Lotus

Her "Burst Brain" character "Black Lotus" (ブラック・ロータス, Burakku Rōtasu) was once known as the Black King (黒王, Kuroō) but after she killed the Red King, she went into hiding. Black Lotus was known as a fearsome model before and after what happened to the Red King. However, she rarely reveals her Black Lotus form. The form of Black Lotus is more technical and robotic than her virtual character. It seems that she can only soar in a short length in the air instead of flying. The character model's color is black and purple. Black Lotus is unique since her limbs are blades instead.


As Black Lotus, her limbs acts as sharp blades capable of cutting through almost any parts of the body upon contact, making her a deadly opponent in close-range combats as her dance is described as "black death waterlily", as well as being immune to grappling and restraining skills such as Static Pressure. Outside of her knowledge of the Brain Burst program and her virtual network knowledge, she has been shown to be a great strategist.
