This episode centers on Yui Morisaki, a high school karate ace with a strong sense of justice, who secretly transforms into the holy light warrior Pony Ceres to battle the evil Zydarg organization. In this premiere, she faces a powerful spider-like monster and a Zydarg leader, gets trapped in webs, loses her virginity in front of someone important, and endures intense humiliation and sexual assault as part of the “terror spider web hell” scenario—blending magical girl tropes with dark, non-con hentai elements typical of ryona/defeat fetish content.
