Following the events of the first novel, a mysterious girl appears to Kamito, who is completely shocked by the fact that she knows his hidden secret. Claire, and Rinslet, not knowing what is going on, get angry at him for being 'immodest' which in turn kick start more comedic events. However, that does not overshadow the seriousness of the novel as well when they are pitted to fight against a person whose origins Kamito knows too well and whom has ties to the very person Kamito is searching for. This book was very fun to read and I hope this light novel gains it's recognition.
So we are introduced to two new characters. One is Fianna and the other one is the villain of the story Jio-something. Jio is a lab-made-demon king (the Japanase sure love their demon kings and stuff). Both characters are nothing special, no depth, zero, nada.
I'll probably update the review since it's quite lacking. But so was the book.
