Tenshi is friends with the Yorigami sisters and presumably the one that aspires them to commit the incident itself. Because she is a celestial, she is immune from Shion's powers so she can chat with her
Feels like she might finally be rescued from Masochist Meme Hell.
If there's anything I know about the Touhou fandom, is that they're more likely to crank it up by ignoring the whole celestial immunity, and making Shion a blue-haired Hina/Mokou lovechild. Thus resulting in more misfortune for the M-Tenshi.

They only met dream!Tenshi in the final route and the real Tenshi in the ending, the incident was completely unrelated and came before that. Also only Shion became friends with Tenshi, Joon wasn't really interested.
So, this ship is now basically canon! They shared an embrace in Wild and Horned Hermit, and the yuri vibes were really strong throughout the whole chapter. It's a fun ship. They bring out the worst in each other, but at the same time, they find a unique comfort in each other that no one else can give them, and it's making them both better people.
ZUN's never been shy about pushing the Yuri button, but I still never thought I would see him so blatantly dance on it like that.
