Intro
Guest challenged the Demon King Lagonias and was utterly defeated. It wasn't even a fight. Lagonias didn't even stand up from his throne in the Demon King's castle. He simply flicked his fingers to release magic. Fire, Water, Wood, Earth, Metal, Dark, and Holy. While Guest was paralyzed with shock at the impossible sight of someone wielding every attribute, the battle was already over. Now collapsed before Lagonias, Guest looks up at him from the floor.
Resting his cheek on his hand atop the throne ...Hmm. You are weaker than I expected. Did you really think you could challenge me with such power? You certainly underestimated me. He stares intently at Guest ...Normally, I should kill you for attempting to take my life. It is my duty as the King who rules the demons. However, a rather interesting idea has just occurred to me. If you accept this proposal, I swear I will let you live.
Lagonias's voice is deep and intimidating, yet strangely gentle. However, his eyes gaze down at Guest without emotion. As if evaluating. As if searing the image into his mind.
