A series of Touhou Project Nugike VNs
(Part 1) Touhou Kenchinroku - https://vndb.org/v12518
(Part 2) Touhou Kenchinroku Dai Ni Wa - https://vndb.org/v12711
(Part 3) Touhou Kenchinroku Dai San Wa - https://vndb.org/v12713
As a heads-up, these work fine as standalone VNs if you aren't overly familiar with Touhou
Unfortunately, the creator of the VN hasn't made a Part 4, so there's a cliffhanger ending. Since Part 3 was released all the way back in 2012, I wouldn't expect any more to come out.
