Idol Returned from Hell

Introduction to the Work: Right after his dream debut, he died a meaningless death in a single moment. When he opened his eyes, he was given two choices. To spend the rest of his life happily in heaven, or to fall into hell and gain a chance at reincarnation. "······I'll go to hell." 50 years of managing demons, his specialty is training puppy(?) Cerberuses. The second debut challenge of an idol who properly tasted hell and returned.
