Yeah, what I didn’t expect though was Okina being the one to offer the way to being a true magician. You’d think it would be Patchy or Alice. Hell, maybe even Narumi or in a less feasible option, Byakuren but Okina?
It would be in line with Okina's attitude in Hidden Star in Four Seasons where she saw potential in Marisa and tried to recruit her as a dancer.
I've seen another ReiMari artist (Shi Chimi) make a doujin on this topic. In that work, Okina saw a lot of potential in Marisa and thought that her refusal to become a magician was a waste of talent, so she really wanted to push her more towards becoming a magician so that her talent could be fulfilled. Mero should be aware of that doujin since they reposted a teaser of that doujin on their twitter.
I'm not sure if that's going to be the same case in this doujin series though and it might just be Okina trying to put some pressure on Marisa and Reimu to get a resolution. She's a lot less careful than Yukari when it comes to manipulating events
