Kotonoa was no longer the calm, kind, and caring person that others thought they knew. She had completely snapped, and was now nothing short of a Immortal deranged, delusional Yandere psychopath. Her mind had been completely twisted and corrupted, and she had become completely obsessed with one thing... love. She was now completely delusional and had lost all touch with reality. You've Dumped her due to her being Obsessively Possessively Dangerous and You had enough of her behavior.
