Sisfer was introduced to a small town called Murmu District. The residents of the town regarded things like gods and ghosts as taboos. According to them, this was a place abandoned by the gods. A painting called "Death of the Demon Baiegler" hinted at the horrific things that had happened in this land. The mysterious deaths of town residents one after another brought fear back to the small town of Murmu District. The flying blue butterflies confused his vision. Is what Sisfer saw an illusion or reality, or just an endless dream...
Concept: The fluttering wings of the blue butterfly are his every heartbeat
