After a long while, I've finally finished another subtitling endeavor. Unlike my first, this one came out far nicer, and has a nice video to go along with it. (The original video was made by a NicoVideo user.)
From Silver Forest's album released at Comiket 73 (東方蒼天歌, Touhou Soutenka), Kero ⑨ Destiny is a remix of Suwako Moriya's theme from Mountain of Faith. The original title is "ケロ⑨ destiny."
(Note: "Kero" is Japanese onomatopoeia for the "ribbit" sound frogs make. "Mishakuji-sama" is another name for the god of the Suwa lake, referring to Suwako.)
