B-SiDE

B-SiDE's most recent release is Holo no Treasure Mountain Tenkomori Ver. Nintendo Switch 2 Edition, sold by CCMC Corp. for Nintendo Switch 2 on Thursday, September 17, 2026 at 2,800 yen. An Upgrade Pass costs 400 yen for owners of the Switch version, and the 3D puzzle game supports Japanese, English, Chinese (Simplified and Traditional), and Russian.

The studio's 2026 catalog also includes Memory of Memorie: A Chill Story, a work companion adventure that launched for PC, Mac, Switch 2, and Switch on July 23. Developer Kazunori Nanji said the Switch version lacked a farewell menu because the console does not require exiting the game, and the team added the feature after fan requests. The episodes are separate releases rather than one continuing product, and neither story gives a title count or a broader release schedule.

The other stories in the cluster do not concern B-SiDE. One covers the end of Waka Sanada's manga adaptation of The Delinquent Girl Beside Me Suddenly Dyed Her Hair Black, which ran in Kadokawa's Monthly Shonen Ace and closes with a fourth volume in late November, published in English by One Peace Books. Another covers BeXide's Ver1.2.0 update for NAMCO LEGENDARY Mountains, which added versus modes on August 25, 2026. A third covers Crunchyroll's English dub for the Tamon's B-Side anime, produced by J.C. Staff, with direction by Helena Walstrom.
