At the Time Photo Studio, partners Lu Guang and Cheng Xiaoshi accept jobs of a peculiar nature. With the aid of their complementary abilities, they are able to leap into photographs—thereby entering the past. One such case involves Liu Siwen, whose only wish is to marry his one true love, Ou Yang. However, her martial arts master father is apprehensive of a suitor who is an outsider and refuses to give his permission unless Liu Siwen defeats him in an honest duel. After years of trying and failing miserably because of his less-than-impressive skills, Liu Siwen finds himself seeking the help of Lu Guang and Cheng Xiaoshi. The two hatch a plan to outwit Ou Yang's father, but what seems simple in theory is rarely as easy to execute in reality…

Among all the beasts that roam the world, there are unique types of "ultimate species" that harbor immense strength and magical prowess considered to be at the top of the power scale. As such, many humans covet their abilities, leading some of these species to the brink of extinction. As a beast tamer, Rein Shroud can employ the assistance of various animals for many tasks, such as reconnaissance and logistics. By virtue of his ability, he joins a party led by the vile and manipulative hero Arios Orlando, only to be banished after six months due to his uselessness as a non-combative class. However, unbeknownst to the team that cast him away, Rein is an exception among beast tamers. His potential becomes apparent when he meets Kanade—a cat spirit who is also one of the ultimate species—and is able to form a contract with her. With Kanade by his side, Rein sets out on his journey as an adventurer, steadily rising up the ranks and meeting more ultimate species along the way.
