まっしろわーるど

「まっしろわーるど」 is the first ending theme for the 2014 television anime 未確認で進行形 (Engaged to the Unidentified). Performed by みかくにんぐッ!, the unit formed by 照井春佳, 松井恵理子, and 吉田有里, it was released by TOHO animation RECORDS as a four-track CD single on January 29, 2014. The anime was animated by Doga Kobo.

Written by 畑亜貴 and composed and arranged by 倉内達矢, the song is a bright J-Pop piece built around quick rhythmic motion, light keyboard colors, and tightly blended group vocals. Its compact melodic phrases keep the verses buoyant, while the chorus opens into a sweeter, playful refrain that emphasizes the unit’s ensemble chemistry.

That tone matches a series that mixes ordinary school and family routines with the awkwardness of an arranged engagement and the strange presence of the Mitsumine siblings in Kobeni’s home. Beyond its anime use, 「まっしろわーるど」 later appeared on the album 『みかくにんぐッ! うたのこれくしょん』, extending the song’s life beyond its original single release.
