They throw together a TOURNAMENT of all 31 girls and pit them against each other and see who wins. >D Not every fight gets an explanation, but 5 of them do--sadly I can't read them :( I'll make Misa do it for me uhuhu HOWEVER! I did go through and look up all the names in the fights, and made a clean version with the romanizations of the names. So now everyone can share in the wtfery . . .
Okay so. I can't read the accompanying text so I'm not really sure of the rules of this battle >D I assume that pactio weapons are allowed (because otherwise there's--absolutely no explanation for Haruna)! And that the fights are all physical in nature, along with assorted magical pactio stuff etc. A-also I'm not sure whether or not Chao is equipped with Cassiopeia because it seemed pretty clear in those chapters that Cassiopeia!Chao owns Setsuna, yet Setsuna beats her here. I KINDA SUSPECT THEY JUST WANTED SETSUNA TO WIN :(
. . . I-I have no idea what the deal with Haruna is. There's a box-thing on the following page explaining her but yeah. XD I mean her power is pretty badass and useful (I'm guessing she probably pwned Kaede with frogs) BUT BEATING EVANGELINE, W-WHAT, NO
I would love to actually see this happen in the manga :/
