Kira is very callous, calm, arrogant, deadly, and overconfident, rarely losing control of the situation. He demonstrates great cunning when handling obstacles and problems. He will kill anyone who gets in his way mercilessly, but compared to the other villains of the franchise, is among the more human antagonists. Kira's status as a serial killer is supported by his inherent desire to not want to draw attention. He simply wants to live a quiet life. However, he has shown to genuinely care/worry.
