I don't if it's voice actress name. Interesting that there is another flavour of Marisa with glasses tagged as Uzuki. This website doesn't load for me. I will change description a bit, thanks
I'm not very knowledgeable about the cookie subfandom, but voice actresses used to voice a certain character seems to get their own personna, with the seiyuu behaviour but the visual of their character. It could be why there are several Marisa with different person tags
