Overview
キミとボクのミライ (Kimi to Boku no Mirai) is an idol-pop number from Cygames' long-running mobile RPG Granblue Fantasy, performed by four fan-favorite characters as a fictional idol group: protagonist Djeeta (CV: Hisako Kanemoto), Lyria (CV: Nao Toyama), Vira (CV: Asami Imai), and Mary (CV: Akiko Hasegawa). The song originated as the centerpiece of the GRANBLUE FANTASY IDOL PROJECT, an elaborate April Fools' Day gag launched by Cygames in 2015 that proved popular enough to earn real television commercial usage and eventual crossover into rhythm games.
The composition was helmed by legendary Final Sequence composer Nobuo Uematsu (植松伸夫) alongside Tsutomu Narita (成田勤), with additional writing by Hidenori Maezawa and lyrics by Cygames and maimie. The brisk 178 BPM drives a bright, energetic melody typical of the idol genre, with each vocalist trading lines in character. In maimai, キミとボクのミライ landed on April 11, 2019 as part of the FiNALE edition, bringing five Standard charts from Basic through Re:Master. The Re:Master chart, designed by Jack at level 12+ (constant 12.7), was a milestone for the Game & Variety (ゲーム＆バラエティ) category: alongside Lost Princess, it was one of the first two songs in that genre ever to receive a Re:Master difficulty in the maimai series.
Region-locked due to Granblue Fantasy licensing terms, the song has never appeared outside Japanese arcade cabinets, a status that has made it a destination track for travelers and import players. It also crossed into SEGA's CHUNITHM AMAZON PLUS on the same day through a Granblue Fantasy collaboration event, initially time-limited then made permanently available.
