I've seen your votes. Majority voted for Mirajane, and I can see why. But a good chunk of you also voted for Ultear. I will admit that Ultear is a very niche pairing, and although Mirajane is popular, she is also one of the most overused romance pairing. But the votes don't lie. I will give it a few more weeks for new readers or old readers to keep putting their votes in the Waifu chapter before finalizing my romance pairing. As it stands:
Mirajane x Shisui is the most popular yet overused.
Ultear x Shisui is not as popular yet niche.
Or perhaps, a Shisui x Ultear x Mirajane? I have a really, and I mean really crazy idea playing in my head that has to do with a Lust Demon (a Demon type along the lines of Nihilora. Meaning ancient Demons that predate Zeref).
Shisui would accept a mission about girls missing from a secluded town, where he happens upon Ultear and Meredy who were investigating a rumoured appearance of Demons in the area. Long story short, Ultear and Shisui has a final fight against the Lust Demon, but in it's defeat, it releases pheromones that makes snusnu (which means this fanfic will officially also hit R18 status with my first lemons). Though they have no feelings for each other, that experience will be the kickstart of the romance building.
It's a crazy, CRAZY idea but it's one that im dangerously leaning towards. Mira fits into this mini harem by the normal romance route, and I'm also thinking of making it so that Mira's She-Devil form is the one to accept a harem because lets face it, vanilla Mira is just too vanilla to accept these kind of relationship. But a case can be made for the She-Devil form to be Mira's representation of her deepest desires, and who knows she might be a little kinky.
Again, these are all just IDEAS at this point, nothing concrete. But I am leaning heavily towards it. If more people vote on Ultear and Mirajane, it might happen. Just placing a warning now for non-harem lovers because this fanfic could very well turn into a mini harem of Shisui x Mira x Ultear
