Regression Hunter Training Center

This is about Yang Chae Jin, a (violent and self-centred) hunter who was betrayed by his trusted teammate and forcefully used as a sacrifice when the whole bunch of them was stuck in a Gate. He regressed 13 times and this is his story about how he eventually, in his latest regression, decides to mature and settle down and open a Training Center for (desperate) hunters and lead his life peacefully (as peacefully as he can) for once. He also finally gets a cat and a proper friend.
