Regarding お天気とチョコレート's status as a KONAMI original
While I don't own or have scans of Liquid Melody to prove whenever it mentions that お天気とチョコレート is licensed by KONAMI, the JASRAC database page for the song (and its remix) states that KME has rights over it, so it would indeed be a KONAMI original. --FinalOffset (talk) 01:46, 25 October 2018 (UTC)
