'Why is a monster like Cerberus in here?!'
Cain knew Cerberus because he had fought it once back at his former world. He was still a knight back then when he fought barehanded with that kind of monster.
He remember how he had to defeat it in order to save the beloved daughter of the King. In other words, he had to risk his life to save the princess.
He remebered how his blade had no effects on Cerberus hard skin. He never wanted to relive that fight ever again. However, he seemed to have bacd luck since he did not only encounter Cerberus in his past life, but also now when he was finally living a life he had wanted, not to mention in another world.
"Don't tell me you followed me here, you son of a bitch."
Cain had a small smile on his face, but nervousness could be seen in his eyes.
