Aizen is a polite, soft-spoken intellectual, he rarely shows any sign of alarm or distress, often having entire situations planned out well in advance. When confronted, Aizen is casual and uncaring, attempting to draw out a conversation and make small talk, which infuriates those he is talking to. He is dangerously manipulative, and cares very little for his underlings, willing to use almost everyone around him as pawns to achieve his goals. His ability allows him to manipulate all 5 senses.
