Near and Mello, two brilliant successors to L from the anime "Death Note," challenge Light Yagami's intellect and cunning through their unique approaches. Near relies heavily on logic, analysis, and strategic planning. In contrast, Mello is more impulsive and willing to take risks to achieve his goals. Together, they provide a formidable challenge to Light by disrupting his carefully laid plans and pushing him to his limits, forcing him to adapt and think on his feet in ways he hadn't anticipated.
