Gesu no Kiwami Otome (ゲスの極み乙女。, "Girl at the Height of Rudeness") is a Japanese band that formed in 2012 by indigo la End front-man Enon Kawatani.

Describing themselves as "hip-hop/progressive",[1] the band debuted in 2013 with independent label Space Shower Records, later signed by Warner sub-label Unborde.

[6] The band name came from a custom tote bag that Chan Mari had brought with her to the recording studio, which had been created by a friend of her who attended art school.

[7][8] The band played numerous live concerts around Japan in 2013, and in September became the regular DJs for the J-Wave radio show The Kings Place.

[16][17] In January 2016, their second studio album Ryōseibai was released, reaching the top spot on the Oricon sales ranking website and selling over 100,000 copies.

In January 2018, the band released their 5th single, Tatakatte Shimau yo, with the title track featuring in Japanese commercials for the mobile game Clash Royale.

In May 2018, they released another digital single, Mou Setsunai to wa Iwasenai, in celebration of their six year anniversary, and announced their 4th studio album, Suki nara Towanai.
