The girl holding the black book (that turns into a dog)
Is blind, she can read magical books, even ones in other languages, using her minds eye. This specific book cannot talk, or be opened without her permission (or the key to the padlock)

the other one is a Magical Girl (random fun fact, CardCaptors Sakura is one of my favourite animated shows of all time)
Anyhow, the cowtato grants her magical girl powers when she asks, she also has a brand of sorts on her wrist to express the bond.

They are both college/university freshmen that requires uniforms. I don't know, i knew they where not highschool age, but i also wanted to give them uniforms.

Blind girlie came from an old dream i had that made me sad. So I decided to redraw and redesign her.
The other is based on the fact i made a "Universal Cowtato" plush for a friend, and though "that would totally be a magic girl sidekick"
