To commemorate the launch of "SAKANAQUARIUM 2026 "Transparency"', the release of the CD single "怪獣/ Kinai" has been decided for Wednesday, September 2.

The included tracks include two deluxe remixes: "怪獣(Cornelius Remix)" by Cornelius and "I Don't Need It (Takkyu Ishino Remix)" by Takkyu Ishino, as well as the drama "Kochira Sebi Jiwai Eiyuho?!" A total of five songs recorded for this release, including 'Ronai Piano ver. (feat. Asuka Kawatoko)', which was performed only in the film as an insert song.

NF member The Limited Edition comes with a Blu-ray disc featuring live footage from the SGC Hall Ariake 'Opening Premier Series' held on April 19 this year. This is a highly planned and valuable live video, featuring the top 10 songs ranked by NF member and tracks selected by TEA M SAKANACTION staff, offering a unique and highly planned atmosphere that differs from SAKANACTION 's usual stoic live performances.

The jacket artwork is linked with the "SAKANAQUARIUM 2026 "Transparency"' tour, featuring a special "transparent" package featuring lyric sheets made from transparent materials enclosed in a silk-printed plastic case. All editions are fully limited editions, so please be sure to pre-order early.
