Kureha (クレハ) is an original Sword Art Online game character and one of the heroines in Sword Art Online: Fatal Bullet. She is the Protagonist's childhood friend and is a well known Gun Gale Online (GGO) player, even recognized by the top players in the game, such as Itsuki, for her reliability and good battle analysis skills.

Gun Gale Online
Kureha has a blue-eyed and pink-haired avatar, with a single ponytail to her right. Her black tanktop and white skirt is accompanied by her prominently pink jacket, along with her white gloves and boots. Her canon choice of weaponry is an Uzi as primary and an optical rocket launcher Deneb Kaitos as a secondary.

Personality
Kureha is a cheerful personality with a lot of energy and confidence in herself. She likes to take the lead when given the chance and is more of a Solo type player, which is the reason why she is known to jump from Squadron to Squadron. Zeliska refers to her as a "happy-go-lucky" type as well.

In the real world, she has a much more reserved personality, living under the shadow of her genius sister, trying her best not to disappoint anyone. While she claims she has the same personality in both the virtual and the real world, later she opens up to the Protagonist about the weight she carries on her shoulder in real life.

Background
Kureha is a long time childhood of the Protagonist. When her family had to move away due to her parents' and her sisters schooling, she got devastated. While her sisters education was the main reason of their move, Kureha never blamed her for it. She did her best trying to live up to the expectations and tried to not disappoint her sister.

Fatal Bullet
Kureha invites the Protagonist to play GGO, because she is in need of a partner for an upcoming tournament. After teaching him the basics of Gun Gale Online, they enter the competition. After messing with a control panel, she accidentally sends the Protagonist through a warp gate.

Going through the gate seconds later, she finds Kirito attacking the Protagonist. As she tries to save him by attacking Kirito, she is promptly stopped by Asuna. After the situation settles, Kureha realizes she just missed her chance at getting a special reward in the form of an ArFA-Sys. Being angry at the Protagonist, she scolds him and claims what's his is hers, at which point, ArFA-Sys registers Kureha as their superior.

Getting close to Kirito and Asuna in the earlier instance, Kureha is invited to Kirito's quarters along with the Protagonist, to meet the rest of the cast. She is quite surprised at the female-to-male ratio of everybody in the room and feels quite glad that she found a group of people, where she wouldn't be designated the "Squadron Mascot" as the only female player. Kureha thanks the Protagonist for "rubbing some of his luck to her" and thanks them by giving a tour of SBC Glocken.

After a while, having learned that ArFA-Sys is the key to unlocking a brand new update area called SBC Flügel, Kureha tags along with the Protagonist and ArFA-Sys to collect parts that was scattered from the ship. During the collectathon, they defeat Bazalt Joe on two seperate occassions in a bet and get vital information from him regarding the ArFA-Sys parts.

When all parts are collected and the SBC Flügel update area is activated, she claims a spot on the 4-person Squad that would assault the ship, along with the Protagonist, ArFA-Sys and Kirito. Upon reaching the ship, they face the Gatekeeper protecting SBC Flügel. Realizing the boss was too powerful and possibly intentionally unbeatable, Kureha teams up with Kirito to act as a diversion on the Gatekeeper, in order to ensure the Protagonist and ArFA-Sys can escape safely, because nobody was certain what would happen to ArFA-Sys as an in-game-item, in case the Protagonist died in action. Shortly after, Kureha returns along with Kirito back to Kirito's quarters in SBC Glocken, explaining they managed to barely escape without dying.

After ArFA-Sys remembered a final requirement and granted them access to SBC Flügel, everyone decides to create a Squadron for ease of access provided by the system. Kureha feels uneasy letting the Protagonist be the Squadron leader, since she was the one taking charge in the group when they were kids. Also not wanting to be granted the leadership by grace, she decides to challenge them into a duel to be the leader, followed by Kirito, Sinon and Yuuki jumping in and turning the duel into a battle royale. She also offers Zeliska and Itsuki a chance to join, but both of them turn down the offer. Kureha loses the battle royale and crowns the Protagonist as the leader.

Despite doing so, Kureha still feels uncomfortable after acting tough, challenging the Protagonist and losing right after and decides to take some time off from the celebrations in Kirito's room. Zeliska finds her in town to talk and Kureha tells her that she also had the impression of others joining the duel was because they knew she would lose and that they wanted to soften the blow. She also opens up about how she has been living under the shadow of her older sister and going through these events just assured her that she was useless, both in the virtual and the real world. She is comforted by Zeliska, not by Zeliska directly arguing with her, but by Zeliska highlighting that everybody feels a certain way from time to time and that everybody needs to vent from time to time.
