Azusa, the Sailor Lightning warrior, harbors a massive electrical energy within her while battling demons every day. This power makes her a threat to demonic forces, marking her as a target for those seeking to resurrect the Demon King. One day, she is challenged by an opponent who takes her beloved childhood friend hostage. The enemy appears as a hideously deformed frog demon, but it's soon revealed to be her childhood friend himself, causing Azusa to lose her will to fight. Exposed to her weakness—water—and drained of power through forced discharge, she is eventually captured and restrained by a special device. Enduring severe torture, Azusa loses all energy and falls completely into enemy hands. What will become of her fate and the future of the world? [BAD END]
