Canon
Marisa and Alcie are neighbors and fellow magicians as both live in the Forest of Magic. In Imperishable Night, they've teamed up as a "bad relationship" combination, and later Alice was supporting Marisa in Subterranean Animism, sending her to the Underworld saying that it was a "onsen-enjoyment game".

Alice seems to have a love-hate relationship of sorts with Marisa, with the two often insulting and fighting each other, yet teaming up on several occasions.

Fanon
MariAri is one of the most popular pairings in the Touhou fandom. Fan works in which they have a relationship vary greatly, with one of the most popular interpretations of MariAri being Alice acting like a typical tsundere (or even a yandere) toward Marisa, usually because Alice is a youkai and Marisa is not.
