In Touhou canon: Satori raise the Devil as her pet

In SAAD AU fanon: Satori has guardian angels as her companion.

P.S. If you ask me why Utsuho is the Devil in my opinion, there are two main reason:

• In The Last Comer, many of Mumumu's attacks resembles Utsuho's sun and bullets attacks, and guess who is Mumumu based on? Of course, is Satan! Also, Mumumu's theme is also contains parts that refers to Utsuho's theme!

• And nuclear power is stereotypically associated with destruction, due to the atomic bombing of Japan occured long ago, and destruction is linked with the Armageddon, an apocalyptic event in which the Devil is involved.

A nice link, right?

P.S.S. I don't make it to defame Touhou nor portraying Utsuho as a bad guy, I still think Utsuho is just a birdbrain who don't know what to do when she is imbued with powers from a goddess, and thus, while being uncontrolled, she is as destructive as the Devil, but she is still not a bad guy.
