Nick used to be a member of a veteran adventurer party, helping his undisciplined friends with the accounts whenever he could. But what was his reward? Getting accused of embezzlement and kicked out by the leader he respected. Before long, he finds a few other jaded adventurers and kindred spirits, and together, they form their own unstoppable party!
Thirty years ago a strange phenomenon called a "spacequake" devastated the center of Eurasia, claiming the lives of at least 150 million people. Since then, smaller spacequakes plague the world on an irregular basis. Shido Itsuka, a seemingly ordinary high schooler comes across a mysterious girl at the ground zero of a spacequake and learns she is one of the "Spirits" who are the real cause of the spacequakes that occur when they manifest themselves in the world. He is recruited to make use of his mysterious ability to seal the Spirits' powers thus stopping them from being a threat to mankind. However, there is a catch: to seal a Spirit's power, he must make her fall in love with him and kiss him.
