Let's go through some basic knowledge before I talk about it further...
Characters: Ashley Ketchum & Misty
Canonical?: Fanon
Relationship status: Acquaintances
Also known as: SatoKasu, KasuSato
What do I think?:
Technically this would be semi-canon, but since most people class Ashley as a separate character, even to the point this ship exists, so I won't put that there
Also, this is very cute!
I shall rate this ship: 6/10 (Same score I put for Pokéshipping)
Thanks for reading, see you in the next chapter!!!
