*Looks at the new scenario* Hmm, looking at the new map, I say we go clockwise as if we start from the bottom village, we'll be stuck in the choke point. Also, if 7, 8, 9 tries to attack us from behind, the archer would be in the front, so we can take her out quickly.Rinnosuke, Nazrin and the magic users sticks to the middle outta of the group while the rest of while the fighters will be in the front and middle inner and rear of the group. Tenshi should be in the rear group since she's slow. Murasa should be in the front, since she's our heavy hitter. Meiling and Reimu take the middle inner. As for Cirno and Kogasa, they could be anywhere but I recommend the in the middle inner.
Note: I'm thinking the map in a circle.
Also, this is just a quick plan, as maybe I'll think of something better later.
