I promised to avenge my parents. But their killer is still at large, and he took not only the lives of my parents. Now he is getting closer to his mysterious goals, and he is ready to destroy what little I have left. I promised to translate the ancient grimoire. But it contains the secrets of my family - and the secret of the history of summoning demons. I'm afraid of his answers, even though I need them. Who was the foremother of Demonica... and who am I? I promised that I would send my demon home. But he looks at me like that, protects me, touches me... how can I drive him away forever? I swore I would do this for him, but could I? Should I? But I promised, and I will keep my promises, even if it costs me my heart, soul and life.
