Overview

"fantastic dreamer" is the first opening theme song of the anime series KonoSuba: God's Blessing on this Wonderful World! (この素晴らしい世界に祝福を!), performed by Machico and composed, arranged, and written by Tomoya Sonoda (園田智也). Released as a single in 2016, the track is an energetic, upbeat pop-rock number that captures the comedic fantasy spirit of the series, driven by a brisk 185 BPM tempo, prominent synth hooks, and Machico's bright vocal delivery. The song made its maimai debut on April 17, 2018, as part of the maimai MiLK edition, where it appears in the POPS & ANIME genre. Due to licensing restrictions, "fantastic dreamer" is available exclusively on Japanese-region maimai cabinets, a limitation that has made it a sought-after play for visitors to Japan. The maimai version uses the TV-size edit of the song (approximately 1:29), while a separate cut of the full version later appeared in SEGA's sister rhythm game オンゲキ (ONGEKI). The chart lineup spans Basic (level 5), Advanced (level 7), Expert (level 10), and Master (level 12, constant 12.5). Over the course of maimai's version history, the difficulty levels have been revised multiple times: the Expert chart, for example, rose from an 8+ in the MiLK era to level 10 by UNiVERSE+, and the Master chart climbed from level 11 to its current 12, reflecting both the game's shifting difficulty scale and the community's evolving skill baseline. The Expert chart was designed by ミストルティン (Mistilteinn), while the Master chart was designed by サファ太 (Safata).
