I can say this one is one of my favorites works from zounose. He did bring up a good topic. The way everyone won zero sum game is interesting. Money is a wanted thing as long as you live in a society for the usefulness in almost situation, so losing money -> the fear, losing money to gain something in advance can still be considered lost in some case, for example a boring book, some silly device you bought in high spirit, spending money for its own sake like in this doujin. Actually value always fluctuates, I'm not telling about price, in different periods and individuals so the case mentioned here will be before and right after exchange to make it simple.

The reason why I said the case in this doujin is a zero sum game is that it is literally the same one in Liar game or nearly. Not everyone is driven by a goal to gain more money but they all fear of losing money and gods are gamemaster. The rule is simple:
+They gives players lots of box and money to purchase
+There are two sides, seller (have boxes, no money) and buyer (have money, no box)
+Each box contains one kind of shape
+Each shape is applied for a team
+If the shape you get is the one of your team, you gain +1; if not, -1
+Players win when they reach (*) points

Following the rule, the act of purchasing is satisfied if the merchandise wrapped in a box so buyers won't know what is inside 'till they open. If sellers can't sell enough of his stuff, and buyers don't buy anything, they lose, except you are a lucky seller with enough right shape from the start. Did you see the point in this game? You actually don't need to use money to win the game but gain more money is the reason you join the game so your motivation actually drives you far from the victory because you scare of losing it and the act of buying any box contains a high risk.

For reasons above, Marisa and those fairies are the first winner.

I'm too lazy to type, so I will stop and not explain deeper.
