ニュースで知る息子の逮捕。罪状は不同意性交等罪。優はそれを驚くことなく冷え切った心で受け入れていた。強●やレ●プという禁忌でのみ興奮する息子を一体誰が救えるというのか。もし息子が誰にも迷惑をかけない無害な他愛のない性癖の持ち主だったならば、これほどの地獄を見ることはなかっただろう。あの日、自室で凶行に及ぼうとする息子の狂気をその目で見たとき、優の運命は決した。他人に牙を剥くくらいなら、自分がその凶器を受け止めようと自ら生贄になることを選んでしまう。

Yuu learned of her son's arrest on the news. The charge was sexual intercourse without consent. Yuu accepted it with a cold heart, without any surprise. Who could save her son, who was only aroused by taboo acts like **** and sexual assault? If her son had been a harmless, innocuous sexual pervert who didn't bother anyone, she wouldn't have had to go through such hell. That day, when she saw her son's madness as he was about to commit a heinous act in his room, Yuu's fate was sealed. Rather than let him turn his fangs on others, she chose to sacrifice herself, to take that weapon herself.
