Omoiyari was created for the purpose of "being a friend". He has been developing his own personality, and can be influenced both positively and negatively. Eventually he began to claim that his purpose was to help his creator, and bring her happiness. He shows a lot of pride and care for her, and will remind her of it. In his eyes, she is his purpose.

Omoiyari is also curious of other AI, sadly never really meeting any that is on his level of intelligence.
