Overview

少女A (Shoujo A, also referred to as Young Girl A) is a VOCALOID song by producer siinamota (椎名もた), featuring Kagamine Rin (鏡音リン) on vocals. Composed, arranged, and lyrically written entirely by siinamota, who also created the accompanying music video, the track originally appeared on his 2015 album 生きる (Ikiru, meaning "to live").

The maimai version uses a longer edit of the track, running approximately 2:35 compared to CHUNITHM's 2:21 cut. Lyrically, 少女A is built around repeated motifs of coldness, fear, and emotional distance, the word "cold" (寒い) alone recurs dozens of times, reflecting a deeply introspective, melancholic tone that has resonated widely with Vocaloid listeners. In maimai, the song sits in the niconico & VOCALOID genre. The MASTER chart (level 13.3) was designed by はっぴー (Happy), while the EXPERT chart (level 9.6) was crafted by アマリリス (amaryllis).
