ふ・れ・ん・ど・し・た・い (romanized as Friend shitai in Asian English releases) is the opening theme song of the 2015 anime series がっこうぐらし！ (School-Live!). The song is performed by 学園生活部 (Gakuen Seikatsubu, the School Living Club), a unit comprising the anime's four main voice actresses: Inori Minase as Yuki Takeya, Ari Ozawa as Kurumi Ebisuzawa, M・A・O as Yuuri Wakasa, and Rie Takahashi as Miki Naoki. The music was composed by Takanori Fujimoto, with lyrics by Kiyomi Kumano and arrangement by Hiroshi Sasaki. The song entered maimai as part of the PiNK PLUS update on July 14, 2016, alongside a dedicated event course that rewarded player icons of the main characters. Its in-game background video draws from the anime's opening animation, though attentive fans have noted slight differences between the game footage and the broadcast version of the OP, reflecting the anime's practice of subtly altering its opening across episodes. The single-CD jacket, released through NBC Universal Entertainment, is used as the in-game jacket art. ふ・れ・ん・ど・し・た・い is notable for being the first maimai song with a Re:MASTER chart to be removed from the series' active lineup. Its chart lineup is anchored by a level‑11 Re:MASTER designed by はっぴー (Happy), which features an unusually high Slide‑note count of 89, more than triple the Slide density of the Master chart, giving it a distinct, flowing pattern character. The Master chart (level 10+, designed by しろいろ) is its own test of precision, with only 6 Hold notes against 418 Taps, creating a relentlessly percussive play experience.
