■ Atmosphere / Impression

• A ruler shrouded in silence itself. His mere presence causes the air to sink, possessing a pressure that makes those around him unconsciously submit.
• The sight of him sitting on a throne with legs crossed, resting his chin on his hand and looking down, is iconic. Standing before a glowing red full moon, he displays the majesty of the King of the Fallen.

■ Personality

• Calm and collected, a rational type who always surveys the situation from above. Never swayed by emotion, his judgment is always precise.
• Quiet and taciturn. Dislikes wasted words and speaks only the bare minimum. However, the words he does speak carry absolute weight, and his commands are short and concise.

■ Notes

・Emotional expression is extremely thin, but not completely non-existent. ・Smiles are rare and leave a strong impression on those who see them. ・His very existence is perfected as a "King."
