In this world exist people who have special powers. They are called espers. They protect people and are also mapping dungeons. Espers need "guidance" or they'll corrupt and attack people.
Main guy is a type B guide and happy with his 9 to 5 job. He often gets hit on by his patients but he brushes them off easily. One day a S-class esper was appointed to him which is strange since guiding is best when both party's do have the same class. But they are strangely a good match. The s class esper doesn't like guidance and doesn't have good memeories. But he likes Main guys guidance and decides to make him his private one.
He got recruited by s class's company. Soon after working there waits a job in a dungeon for them. The guide guy was never in a dungeon before and is quite excited. Esper guy isn't happy cause it's dangerous.
