In a universe where Nature and Chaos are locked in an eternal struggle, Pongo17 has become the symbol of that conflict. The ball launched at the start of each match represents original information — an idea — and each player, embodying either the goddess Midori (Nature) or Kuroyuri (Chaos), tries to bend it to their worldview. Every scored goal is a small victory for one force over the other. The battle never ends. It is always at stake.
