Normal people awaken their superpowers in their teenage years. At thirty-two, an ordinary man gets his — along with a draft notice from the Department of Defense and ninety days before deployment to a dungeon. His class is [Trainer], with zero available familiars. But the System made a critical mistake: it allowed him to assign a familiar to himself. Now every cell in his body is a pet that can be trained. He can issue special commands to his own biology — fall asleep instantly, ignore pain limits, evolve faster than any young genius. He is his own trainer, and he will not stop until he turns this old body into the perfect weapon.
