Let's see, if we only go for the ones you've mentioned for the moment, and pretend we only do single battles, let's see.
If we first go for only those who only has one possible opponent, we have Dawkin VS Ewan, Abigail VS Ellyn, Ren VS Rodger, Lucian VS Oaken, Erika VS Maple, Martin VS Simon, Donna VS either Joshua or Cathia, and then Claire said she could take whoever's left and
@Keyblade87 hasn't reported yet (can take that data anytime~), which would then be against whichever Donna didn't fight and Vivia.
However, we're more adaptable than that and I just worked out that logic for my own amusement. XD
What's that Dymanic Duo battle you're talking about? Is that Claire and Erika, then, as they're the only two to have decided to partner up so far? And yes, Joshua and Ewan are... um... they know one another pretty well. XD
So then that'd be...
Counting that Erika and Claire has a double-battle against Joshua and Ewan, we'll then have that... Hm. If Ren can imagine partnering up with Lucian, she can fight both her desired opponents in Rodger and Oaken, haha. Then there's...
Oy, this is complicated. Both Abigail and Martin has Simon marked, but also one who has no other possible opponent. But, if both chose away from Simon, Simon will be rendered without opponent! Same way, if either picks Simon, then Ellyn or Maple will be without! XD ... Hey, Dawkin. Join them in a triple battle and we can have Dawkin, Abigail and Martin VS Simon, Ellyn and Maple! XD (you do not need to take my suggestions seriously) And then Donna and Cathia worked together pretty well, yeah. Unless, of course, you want to partake in strange multi-battles as well, of course. As you said you were open to. It'd be kind of lonely not to. Join into that last battle? ... If that's not troublesome. Actually, we can just match and pair you two into any other fight and add a combatant on each side, hahaha...
Of course, lots can be fixed with multi-battles. Though, depending on how things are handled IC, that can be difficult to arrange. Hahaha. In any case.
No love for Vivia, huh. Nobody likes accidental traitors that drag the scene out for me to explain how she got there. Hahaha.
So! What are you guys' thoughts, suggestions and objections to what I have thought about above to fix this all? Did I make any mistakes? Haha. And yes, I am a lot more adaptable than I've shown here. I just wanted to amuse myself by working with logic, really. XD
Edit: I will mention that I did see the mention of Erika's desire to be on her own the first fight. It was just the Dynamic Duo thing that sounded weird to me. Maybe I made a mistake in assuming that. Looking back, you said "from time to time", which is significantly different from "now". Eh, just go by the first schematic then. Haha.
Correct me anywhere I'm wrong. If she wanted to be on her own, then yeah. That'd be the Maple fight, which would then mean Martin VS Simon and then Dawkin is free to fight whoever, and that's that. ... BUT I'M STILL MORE ADAPTABLE THAN THAT! XD
