好き！雪！本気マジック ("Suki! Yuki! Honki Magic") is an official SNOW MIKU theme song produced by the Vocaloid creator Mitchie M, featuring Hatsune Miku. The title strings together three Japanese words, 好き (suki, "love"), 雪 (yuki, "snow"), and 本気マジック (honki majikku, "serious magic"), into a playful, rhyming phrase that captures the festive winter theme of the SNOW MIKU campaign, which promotes the Sapporo Snow Festival each year with a snow-themed version of Hatsune Miku. Mitchie M is widely known in the Vocaloid community for his signature "super-realistic" tuning, which gives Hatsune Miku's vocals a natural, human-like quality with subtle pitch bends and dynamic expression. This track follows that style: an upbeat pop arrangement with a driving synth backbone, cheerful melody, and Miku's characteristically bright yet finely tuned voice carrying lyrics about winter romance and magical encounters. The song was added to maimai on January 9, 2018, as part of the MiLK version under the niconico & Vocaloid genre. Across subsequent maimai updates, the difficulty levels of its charts were adjusted multiple times, reflecting both the game's evolving difficulty curve and the community's growing mastery of the track. The Expert and Master charts were both designed by はっぴー, with the Master chart notable for its high Slide-note density, 122 Slide notes out of 686 total, making up roughly 18% of the chart and giving the upper difficulty a distinctive, flowing hand movement pattern.
