"Hello London 2016, It's me. The devil."

― Ayaze[source]

Ayane "Ayaze" Zehetbauer is one of the main characters in the UKSRT series, and is the series mascot. Created by Koizumi, she has been present since the first instalment, UKSRT1 (2012). The character also predates UKSRT by a fair bit, appearing in various projects (stepmania and otherwise) including MAWARU FINALE (2011).

Ayaze can be seen of as more of an "actor" than a consistent character, appearing in various different mediums and types of game under different roles wherever appropriate, with a backstory that can change as the situation calls for it. Due to this, Ayaze can sometimes be seen as a "dimension hopper", jumping between different realms and changing art style as appropriate.


Ayaze has had a number of different outfits and slightly different hairstyles over the years, but her appearance is consistently characterized by her being tall, having long red hair worn in twintails, red glasses (not needed for sight) and red/blue heterochromia.

More recently, she has taken to having drill-type curls with white tips at the end of her twintails.


Ayaze's personality is generally incredibly self-serving, which usually leads her to being an antagonist, but is not actually evil. She would be very quick to sell out her friends for personal gain, but does generally try to avoid harm coming to people she cares about.


Ayaze has a friendly rivalry with Laer, where they constantly berate each other, but deep down she believes they are friends.

Not much is known about her younger brother Koizumi, but she probably abuses him constantly.

Powers and abilities

In UKSRT, within simfiles (and only within simfiles), Ayaze has the ability to summon red lasers and other forms of bolts of energy, but her preferred form of mod is to make references to other rhythm games.

Major appearances


Ayaze appears at the end of both UKSRT1 and 2 with intent to steal the prize money from the entrants.


Ayaze takes on the role of drill instructor in UKSRT3, to help train the players in preparation for the imminent angel attacks. Before the final round, she attempts to hold off Zeruel but is defeated instantly. In the phantasm stage, Ayaze attempts to use her red laser to hold off Kaworu as he tries to initiate the third impact, but is eventually speared with the Lance of Longinus, and most other in-universe characters are destroyed in the third impact.


UKSRT6: Bravely Segfault is a non-canon Bravely Default parody in which Ayaze plays the role of Airy.

UKSRT Summer 2015

This event is a what-if scenario in the distant future, in which Ayaze owns a Private Military Coporation, and is developing a Metal Gear. Though Havox is non canon, the Metal Gear she uses in that battle originates from this timeline.

Mods Boot Camp

Ayaze is the antagonist of the first Mods Boot Camp, where she stowed away on the plane Laer took to the event, and hijacked the mod files from WinDEU and used them to harshly train the entrants for future tournaments.

Virus Arc (UKSRT8-11)

In SRT8, Ayaze is one of the nurses working at North Inver Tower's Gate Hospital. She is indirectly responsible for the SHAME outbreak occuring (by opening a door in Chan's face while he's holding a vial containing the sample), though she still blames Chan to this day.

During the events of SRT9, Ayaze is the one who connects [REDACTED]'s old PC while accidentally crosswiring it with the Prototype Mind Transfer Device, causing the main cast to be sucked into the PC.



Ayaze cameos as one of the Arrow-kun in stage 3 (Octopus dance/Neurotoxin).


Ayaze cameos in the very intro, asking if it's her that's going to be the successor to the god of spacetime. (She isn't).

She also cameos as the host of MAWARUCHI SURVIVER, SRT5 stage 3, cosplaying as The Princess of the Crystal from Penguindrum.


Ayaze appears as one of the main cast attempting to find out what's going wrong, and is mostly present to act as a foil for Laer. She is possessed by Cuphea along with the rest of the cast before the final round.

Galactic Gladiators

Ayaze appears here as one of the gladiators. Her stage is basically a Mawaru. For the final round, she brings back the Metal Gear from Summer 2015.
