The man was abused by his parents during his childhood. In February, just before graduating from high school, his only ally, his grandmother, passed away due to illness. The man fell into despair. And he contemplated. “If Granny isn’t around anymore, I guess it doesn’t matter what happens.” The man stabbed his parents. Over and over again. And then, he had a sudden thought. He found pleasure in mu*der. Afterward, he killed those who had bullied him throughout elementary, middle, and high school, including teachers who had turned a blind eye or were involved. With a sense of satisfaction after completing his deeds while intoxicated by the thrill, he took his own life. When the man next awoke, he found himself inexplicably transformed into a bat.
