Purgatory

Michael had no idea how much time passed. He could only tell that his insides were torn apart and burned to a cinder. At least, that's what it felt like as the white flames flooded his body.

However, Michael was not the only one in pain. His Curse released a terrifying roar that resounded through his insides. Yet, instead of sounding menacingly, the Curse sounded in pain. Even the World Serpent wasn't much different. It hissed in pain and wiggled around as if trying to escape the white flames.

Michael could endure the pain. It tore him apart and threatened to kill him, but Michael was certain that he was familiar enough with pain to tell that he would survive. However, his brother was different. Even Danny's Living Soul was affected by the white flames. It was unclear how the white flames managed to enter the Soul Grimoire, but they reached the Living Soul of his brother. That filled Michael's heart with worry.
