I have a new idea:
Instead of my idea being Touhou 15, it's 15.5: Peace and Chaos Border (PaCB)
Essentially, it's a spin-off game that is a boss rush of
every single boss
and midboss since EoSD.
Plot Point: Yukari accidentally destroyed the border between order and chaos and is too lazy to fix it, and all of the bosses start to attack Reimu and co., where they go to solve the incident.
Along with that, the bosses also have their respective game gimmicks: Yuyuko has cherry blossoms, Remilia has nothing at all, Byakeren has her UFO's, Miko's divine spirit desires, the Dwarf's autocollect-fragment-get, etc.
Yukari is the final boss. An embodiment of chaos is the EX boss.
Playable Characters:
- Reimu (Same as TD)
- Marisa (Same as TD)
- Sakuya (Unlockable, beat Sakuya in Story) (UF Same as PCB SakuyaA, F Same as DDC SakuyaA)
- Sanae (Unlockable, beat Sanae in Story) (Combination of UF TD and F IN)
- Youmu (Unlockable, beat Youmu in Story) (Same as TD)
All characters get their respective
And no, you don't get your partner system in IN or SA, due to the chaos in Gensyoko.
And no, the fighting games don't count, if they don't get danmaku patterns.
I'm really overthinking this.
