Touhou Kouryudou ~ Unconnected Marketeers. is a bullet-hell shooter from Team Shanghai Alice, and the eighteenth entry in the Touhou Project. Its story begins with mysterious ability cards circulating through Gensokyo. Hakurei Reimu investigates their sellers, while other familiar characters pursue the cards for their own reasons, from curiosity to orders from the Scarlet Devil Mansion.
The core challenge is to dodge vividly colored, firework-like bullet patterns and defeat enemies in short, concentrated battles. The game asks players to rely on technique and memory, while ability cards add another layer: they can be equipped before play and have a variety of effects. The cards are also central to the mystery, with secrets tied to humans and youkai, and questions about who made them and why they are being traded.
That combination gives the shooter a distinctive focus: precise pattern avoidance sits alongside a card system woven into the plot. Reimu, Marisa, Sakuya and Sanae each have separate motives for pursuing the cards, tying the playable cast to the investigation. Rather than treating the cards as a detached collection feature, the premise makes their strange circulation the reason the characters enter the fray.
