Explosive Power

Exploration Stage: Emperor's Palace
From: Huntress
Description: The reports of the imperial commanders mentioned "an unprecedented weapon in the hands of the enemy general", "a rod shooting flames and winged arrows". Was Yui really armed with something like this?! A monstrous weapon of revenge, the reasons for which we do not know. Look for thie phenomenal weapon.
Completed: These Winged Fire Arrows were hardly invented by a mere human! Look, and here's the extraordinary flamethrower. There are no arrows left in the Quiver... Only a roll of scarlet paper.
