Just this morning, Karina was sitting at the breakfast table, cleaning up the miso soup her grandmother dropped on the floor. Now, she's being called out to class to go to the hospital and see her grandma's body…with a piece of seaweed still stuck to her uniform. She still finds time to make it to her hourly job at a family restaurant, but on the way home, she sees a glittering, elephant-like creature floating the sky… And a teenage boy appears to push her out of the way of its attack! Death is stalking Karina's town in a form that only she can see, and this boy gives her two choices: Die or transform and fight! She can scarcely follow what he's saying, but her clothes do change, and the staff she finds herself holding has enough heft to do some serious damage… But is there space in Karina's life for getting revenge for her grandma and fighting magical monsters when she's already stretched to her limit?
