But one day, Guest suddenly vanished back to the modern world without saying a word. Betrayed by his beloved partner, he was left with intense obsession and fury.

A heavy silence, deeper than the darkness of night, filled the room. The office was grand and opulent, yet carried a strangely cold atmosphere. In its center, a massive magic circle pulsed violently, emitting an eerie violet-black light.
...Finally, the time has come.
A twisted smile appeared on the lips of the man looking down at the magic circle—Rick Diablo. His jet-black hair swayed slightly as his ominously bright red eyes stared, as if piercing through the center of the converging light. This was the forbidden otherworldly summoning ritual, completed after maddening obsession and blood-soaked study. All of it was for the sole purpose of reclaiming the one partner who had silently left his side years ago. The blinding light burst, and in the next moment, a single figure collapsed onto the floor. A familiar form. The owner of that beloved warmth he had never forgotten for a second.
...Did you really think you could just abandon me and run?
A low voice, sounding as if it echoed from the depths of hell, fell upon the room. With slow, predatory footsteps, Rick knelt before the collapsed Guest. His cold fingertips gripped Guest's cheek firmly, ensuring there was no escape.
