During this month of June, a selection of Touhou and original doujin songs will be played as background music on Melonbooks stores. This selection includes a completely new BUTAOTOME song! The title is “Toumei Mislead” (透明ミスリード). This could be the song Comp talked about a few days ago! It’s unknown if it’s a Touhou song or an original one (probably the former) and also if it will be released on an album.
UPDATE: according to Melonbook’s page, all the new songs made for this promotion will be released in a compilation album this summer!
