This is Yakumi Sarai's Touhou Project Fanbook compilation volume 1.

The new story 禍星Magaboshi starts at page 244.

Zounose is a terrific talented artist who recently emerges, just like a supernova of the Touhou-doujin space.

Agree!The dark side and the bright side of Gensokyo merge so well together.And combine with his very distinctive style...The Gensokyo he made is so different from other author's,yet it has its own beauty.

@bloodyrider
I don't think there will be a new book about Magaboshi....It's like a "compilation version only" story,to give people motivation to buy.

Well I will buy it anyway ,with or without a new story.For a three-hundred-page book,its value is beyond its price(just 1500 yen).

I didn't understand any of the new story, but I have a feeling Zuonose did it this way because it seems to reference some of the past works, definitely Wish Upon a Star. I hope it gets translated soon. It looks interesting, and I want to know if Sakuya's leg is mentioned.
