東方夢終劇 Concealed the Conclusion

Touhou Mutsuigeki: Concealed the Conclusion is a Touhou Project fangame by danmaq, originally a script set for Touhou Danmakufu and later rewritten using Microsoft XNA. It is the second game in Danmaq's alternative Touhou series, and has massive improvements over the first game - The Alternative Age.
The game is an overall reference as to what could happen if something happened to the current Shrine Maiden in official terms, seeing that the Miko of Hakurei is crucial to Gensokyo's survival or, rather, it is based on a theory.
