人里離れた山奥に建つ
古き伝統を持つ由緒ある女学院。
だが、その重い鉄の門扉の向こうには
残酷非道な『魔女』たちが隠れ棲んでいた。
古き学び舎の奥で
炎上事件の専門家（エキスパート）大和正義を迎えるのは、
清廉な令嬢か、或いは邪淫の魍魎か――？
Located deep in the mountains, far from civilization, is a venerable girls' school with an ancient tradition.
However, behind its heavy iron gates,
cruel and ruthless "witches" hide and live.
Will Yamato Masayoshi, an expert on flaming incidents, be greeted in the depths of the ancient school by
an upstanding young lady, or a wicked monster?
