Twins

The first time the Life Or Death Ring opened was a very long ago back when Darkness Port had just been founded.

The duo who started the first Life Or Death battle were the founders of the city. Later in the naval warfare, the current mysterious Island Master had seized victory by slashing the opponent.

The second time it was opened was over 90 years ago. The duo who started the second Life Or Death battle were two of the top 10 legends in the Purple Moon era. 108 quincuncial piles had been erected on the sea under the moon, and the victor had won by a palm's advantage, striking the loser off the pile.

After that, the victor of the second Life Or Death battle became the first man who founded a safety city single-handedly.

As for the third, fourth, fifth and sixth battles, every participant had been a famous figure in the Purple Moon era.
