After Rias, Akeno, Koneko, Xenovia, Asia, and Irina, along with the people he considered his brothers like Kiba and Gasper, spoke harshly and unreservedly, causing Issei to feel betrayed and used, one person stood out: Ravel. Despite the others berating him, she never uttered anything cruel, unlike the others. However, the feeling of betrayal persisted until Rias' final words sealed their fates in the ORC room. At that moment, Issei snapped, unable to bear the harsh words any longer. Rias said something that broke something within him, something she would soon regret. Unfortunately, by the time she realized her mistake, it was too late. Her words had been spoken and could never be unspoken. Consequently, Issei's heart shattered, and unbeknownst to everyone, they had unintentionally awakened a dormant monster residing within him. Soon, this monster would reveal itself and demonstrate why one should never disturb a creature that was meant to remain dormant.
