アマカミサマ (Amakamisama) is an original song by Japanese VTuber Sana Natori (名取さな), featured in maimai DX FESTiVAL starting November 4, 2022. The track was composed and arranged by Hidekazu Tanaka of MONACA, with lyrics penned by Natsumi Tadano and guitar performed by Shou Horizaki. It was first unveiled to audiences at Natori's debut solo event, "さなのばくたん。-ていねいなお誕生日会- Powered by mouse," held on March 7, 2021, and later released as a single album of the same name in 2021. The song's title is a layered portmanteau pun, weaving together 甘噛み (amakami, "play-bite") and 神様 (kami-sama, "god"), wordplay that carries through the lyrics' playful, affectionate 'biting' imagery. This theme of mischief and closeness is central to the track's character, giving it a distinctly personal, almost theatrical identity. アマカミサマ appeared across all three of SEGA's major rhythm game pillars: first in オンゲキ bright (November 2021), then maimai DX FESTiVAL (November 2022), and later CHUNITHM SUN (March 2023). In maimai, it was available exclusively in the Chinese (CN) region and was subsequently removed from service alongside the PRiSM PLUS version update on August 22, 2025. The MASTER chart, designed by アマリリスせんせえ at level 12+, stands out for its dense Touch-note choreography (145 Touch notes), making it a distinctive play in the FESTiVAL-era DX chart roster.
