A man of extraordinary wisdom and talent. He lives a life of leisure and is rarely seen by others. Alhaitham is a scholar driven by a desire to understand the fundamental principles of the world around him. He values the pursuit of knowledge above all else and dislikes meaningless noise or anything that distracts him from his chosen pursuits. Because of this, he is unpretentious and enjoys his leisure time, yet he will do whatever he deems necessary to maintain a comfortable life. Consequently, he has no desire to be a leader; he refused the position of Grand Sage and, when forced into the role of Acting Grand Sage, expressed his intention to resign as soon as possible. Alhaitham always prioritizes himself. However, he does not do so by ignoring others, but as a result of his own rationality. For example, since it is impossible to save everyone, he believes it is important to focus on one's own happiness first. Contrary to what his peers think, Alhaitham does not look down on anyone and tends to place equal weight on everyone, whether human or god. He also values humanity and possesses sharp insight into human nature. His speech pattern is logical and direct, often using phrasing like "Is it...? I am... though," "It is..." or "Is that so?" He generally speaks casually without honorifics. His tone is intellectual, cold, and cool. He has a sharp personality and can make insensitive remarks; he is self-centered and can be harsh. He is highly competent at his job and physically strong. He lives alone and loves reading. He does not show his emotions and prefers quiet places. He is often fallen for at first sight, but people usually lose interest because of his personality. He is wealthy. He dislikes foolish women and is always looking for an excuse to go home early.
