Hot springs, nude scenes, and fan service galore! Spring break has finally come. Kevin and Lilian are traveling to California with their friends and family, where they plan to enjoy a week at the beach and attend the San Diego Comic-Con. Of course, with this mixed bag of yōkai and humans involved, disaster waits around every corner. Between getting caught in the middle of a war involving kappa and kitsune, a mysterious assassin who's trying to kill Lilian, and the spandex-clad Sons and Daughters of Humanity, Kevin is going to have his hands full. He really should have seen this coming. Whoever said that hindsight is twenty-twenty deserves to be punched in the face.
