In 2021, concurrently with the release of Tsukihime -A piece of blue glass moon-, Type-Moon announced their planned release of Tsukihime -The other side of red garden- as the second half of the Tsukihime remake. They didn't announce any particular plans for release date or even release year. So let's try to figure the release year out ourselves, instead!

This market is planned to resolve upon the next full release of a visual novel comprising part of the Tsukihime remake. (In any language; this is not gated on, for example, a release in English.) This applies even in the event that its name-at-release-time ends up being something other than 'Tsukihime -The other side of red garden-', even in the event the remake ends up being subdivided further such that the next release isn't the final one, et cetera. However, this does not apply to, for example, a demo; only a full VN-release, of comparable definitiveness to the Tsukihime -A piece of blue glass moon- release, will lead to market-resolution.
