True Burn ERC20 Token

Contract Renounced, LP Burned

Welcome to AGNI KAI

An Agni Kai is a traditional firebender duel that is centuries old. It is a fight for one's honor 
and is won only when one opponent burns the other. The outcome of an Agni Kai affects the honor of 
each opponent. These duels are a popular method of resolving conflicts and are a source of entertainment 
for all spectators. The Fire Nation Royal Palace even houses a special Agni Kai chamber.

Any firebender may participate in an Agni Kai. Fire Lords can also be challenged, but that rarely occurs, 
as most Fire Lords are among the most powerful firebenders in the world.
