ゆっくりしていってね！！！ (Yukkuri Shite Itte ne!!!) is a Hatsune Miku Vocaloid original song by the producer 今日犬 (Kyouinu), added to maimai MURASAKi on January 24, 2017. The title, which translates to "Please take it easy!!!", is a deeply embedded Japanese internet meme, originating from a 2channel thread involving the Touhou Project character Yukari Yakumo, the phrase later evolved into the "yukkuri" image-macro characters that became a staple of Japanese imageboard culture. The song plays on this meme with deliberate irony: its commanding 221 BPM tempo, among the fastest in the niconico & Vocaloid category, directly contradicts the "slow down" message of its title, a gag that helped it gain traction on niconico. In maimai, the song belongs to the niconico & Vocaloid genre (niconico＆ボーカロイド) and has remained available for standard play since its debut. Over the course of maimai DX updates, both the Expert and Master charts received notable upward level re-ratings, Expert climbing from 9+ in MURASAKi to 11+ by FESTIVAL, and Master rising from 11+ to 13+, reflecting the community's evolving assessment of their difficulty. The Master chart was designed by はっぴー and the Expert chart by 玉子豆腐.
