Fire Sword

The Fire Sword was used by Hōki, them by Seimei. It is able to emit and freely manipulate vast amounts of fire, capable of incinerating whatever is in its path. It can be used to send light beams as signals through the green sphere at the end of the blade. It can also be used to summon the Infinite Armour, the Garian Sword, & the Weaknessless Soaring Shortswords.
