Light Yagami

Light is a young man, standing at above average height with light-brown hair and brown eyes. During Part I, when not wearing his school uniform, which consists of a tan suit and red tie, he dresses fairly casually, sometimes sporting a dress shirt underneath a jacket or a V-neck sweater with a collared t-shirt underneath. During Part II, if not wearing a similar style of clothes, he is seen wearing a suit.

He is considered to be quite handsome, a trait noted by Misa Amane and Kiyomi Takada, among others.

Light is characterized as hardworking, talented, and a natural genius. Highly perceptive and good with problem solving skills, Light is a skilled planner and good at mapping out scenarios. Furthermore, Light is very popular among his peers and adored by his family members. However, his high intelligence and constant praise from adults laid the foundation for an intense level of hubris, which quickly took effect once he obtained the notebook.

Similar to his father, Soichiro, Light has a strong sense of justice, but this quickly becomes warped after he becomes tainted by the notebook’s power. Believing the world to be "rotten," he uses his Death Note as a means by which he can enact his will to rid the world of evil people. Light's main goal is to create a new world that is free of injustice and populated only with people whom he deems honest and kind, thus becoming the "God of the new world". Light is decisive and driven to achieve his ambitions, without faltering one bit in his beliefs. Despite knowing the criminality of murder, Light would consider his actions the ultimate "sacrifice" to help the world.

Through the use of the Death Note, Light quickly begins to develop a cold and ruthless nature. As a utilitarian, he will use any means necessary to achieve his goals. However, though his actions do put his family in harm’s way, he continues to show love and genuine concern for them. This is demonstrated when his sister Sayu is kidnapped and held for ransom; Light prevents Soichiro from taking drastic action in order to keep Sayu safe, in spite of knowingly increasing Mello's chances of obtaining the Death Note.

Nevertheless, across adaptations, Light has consistently been portrayed as an idealist and as an individual who is willing to go to extreme measures in order to defend his idea of justice.

Light is a kinky and demanding top. He does not care much for consent and is typically rough.
