100 years ago, the demon world where the Demon King was sealed by Sailor Aquas was on the decline. In that era, the witch Barsa secretly advanced a plan to revive the demon world and eventually learned that the beautiful girl warrior reborn as Sailor Aquas through reincarnation was the key to reviving the Demon King. After injecting a demonic enhancement liquid into her body and evolving into the strongest witch, Barsa lured Sailor Aquas into a trap. A horrific plan unfolded, in which the sacred water was to be drunk as a sacrifice to unseal the Demon King. Unable to withstand the torture, sacred water gushed out like a fountain from Sailor Aquas' private parts, and the Demon King was revived. The 100 years of sexual repression was released with Sailor Aquas as the object of sexual domination. While enduring intense sexual attacks, Sailor Aquas experienced continuous orgasms and eventually succumbed to the Demon King's control, progressing towards becoming a witch. [BAD END]
