1. She might be acquainted with Shinki due to similarities between her and Devil's Recitation spellcard.
2. There has been no mention of a separate Makai
3. Shinki supposedly created Makai, enforcing reason no. 1 (since she'd obviously have something to do with someone sealed in her realm)
4. We all know that Marisa "possibly" respect Mima.
Event in Mystic Square was taking place in Makai. PC98 era ends after Mystic Square,and Mima's whereabouts remain unknown.
Taken from Mima's profile. She supposedly living behind Hakurei Shrine. But apparently, the ones who living there currently are 3 Mischievous fairies, not Mima. So, where did she went to ?
Possibly, she lives in Makai now. Considering she is a ghost by the very start, and she looks enjoying the atmosphere in Makai as shown in Mystic Square (if I remember correctly).
What's the relation ?
UFO stage 4, Murasa told Marisa that Palanquin Ship will go to Makai.
Unexpectedly, Marisa looks excited. Why she has to be excited while she ever visit Makai in Mystic Square event ?
tl;dr Assumption time !
