Len'en Wiki

The Len'en Project (鏈縁Project) is a series of vertical danmaku shooting games made by JynX. Although it takes inspiration from the Touhou Project, the games are technically not fangames towards Touhou and that it's set in a separate world which features an entirely new cast of characters, therefore having its own canonicity. Also of note is that while in Touhou the characters are all female, in Len'en the characters' genders are generally left ambiguous. It is likely that their genders will never be revealed, and that it will simply be up to the player's interpretation. Neutral pronouns will be used.
