Amusement Makers is a college club.
Why would you ever think that someone would make a Touhou game about youkai going extinct anyway? The entire point of Gensokyo is that youkai can live relatively peacefully, separate from the outside world.
Oh i get it, then ZUN will sell touhou franchise to DANGOYA (the one who made Kekkai Gensou Rokukyou Mythical Mirror).
For the new era of Touhou
God Reimu can manipulate the boundaries anywhere (like Yukari`s ability), light energy shape-shifting ability and Spell card mixer.
Angel Marisa can control 10 mini-hakero flying around and her master spark is much bigger than ever, also her magic ability is similar to Sariel and Gengetsu.
Future Sakuya is a vampire hunter, her knives can shoot lasers while flying like funnels, if she can`t control her knives properly, it may explode in impact.
Future Youmu wears a high school uniform, she is a sword collector, she can summon 100,000 swords (Just like Gates of Babylon from Fate anime series).
Future Sanae is so casual and her new spellcards is all about Christian bible references.
Everytime they kill every single Youkai, Dead youkai will be reborn into human again, Good youkai will be sent to Gensokyo while Bad youkai will be killed.
Generic enemies are no longer small fairies, Walking Onis and Generic random small youkai will become the new generic enemies.
The final destination of their journey will be Kyoto, the place were indestructible overpowered Youkai live.
Konngara, Fake Amaterasu and Lilith will be the last final boss for the new era of touhou.
