She is a teenage female Sumo wrestler who idolizes Ganryu. The original idea was proposed for Tekken Tag Tournament 2, but was discarded 5 seconds later in order to focus on increasing the popularity of Ganryu. A character sketch was completed several years ago, and the result was of a cute character, like those found in Idol Master.
In November 2013, the sketch was later revealed by series producer Katsuhiro Harada on his Twitter account, in which he also stated that if the tweet is retweeted 1000 times, he would try to convince the staff to complete her design and have her considered again as a playable character for Tekken Revolution. As of early December 2013, she has garnered just under half the expectation.
