It's funny how some people in the Pokémon world can have psychic powers like that as if it was an ordinary ability. If it was here they'd be millionaires.
Pixiv tags this with 女勇者 (female hero), so that's not a male Loto.
Also, that hooded guy in the portrait is Loto's dad (Ortega). That's how his sprite appears in the original Famicom version of the game. Created a tag for him and removed character_request.
So it seems like Saki really has a ponytail, even in her official art. I didn't notice it at first and thought it was just short hair (like Aya's).
That's pretty nice since it makes her stand out more. Ponytails are kinda rare in Touhous, and the only ones that come to mind are Futo and Yorihime (but I may be forgetting others).
