The Magician article in PMiSS notes that youkai magicians are somewhat unique among youkai for being basically identical to humans physically (or even weaker in Patchy's case), with the only difference being their natural ability to use magic. They're not even born unaging but have to figure that out the same as human magicians, just with something of a head start in terms of magic skill.

That explains everything, actually. Thank you Levander!

Is Patchouli really asthmatic in canon?

Yeah, she mentions having Asthma in the ex stage for EoSD. Which is odd now that I think about it, because she's said to be a natural born magician, so I assume that means she was born a youkai? So youkai, the creatures born from human fear and imagination, can have asthma. Can they have other medical conditions? Like, do they have to worry about the common cold, or cancer?

Anyways this chapter was great, PatchiAli is a good ship.
Also that explains what the book from the previous chapter was, but is that all was meant to accomplish narratively? The way Yukari looked at it made it seem more important somehow.

That Shou Byakuren chapter gave me bliss for the rest of the day, and now we get a bit of Meisaku AND a Yuuma cameo? Mero is wonderful.
Also, it looks like Reimu's finally figured it out too! What was up with the book Yukari was looking at meaningfully?

Shou and Byakuren art? By the artist for Love Colored Boundary? I can sleep happy tonight.
