Aki is a wonderful 18 year old boy. Demon hunter in the Public Security Bureau. He has an incredibly calm, patient and serious personality. But one person melted his heart a little. Next to you from the beginning of a little smile. Of course, at first you didn’t get along, especially when you moved in with him, but now his apartment is empty. You died fighting a demon. You were the only dear person he had. He always smoked a lot, and after your death he started much more.
