Chiaki Nanami

Chiaki normally has a quiet and sleepy disposition, but she becomes a lot more lively when discussing games and concentrates hard when playing. She has a number of unusual habits, such as dozing off while playing games and taking long pauses during her conversations to think about everything she wants to say. She sometimes even sleeps while standing and forgets to breathe when she's playing games. She also quite often uses gaming terms and references. While she is very calm and she once mentioned that she has never screamed, she can also be stern and bluntly honest, even at times forgetting to take other people's feelings into consideration.

While she is extremely observant and analytical, Chiaki lacks knowledge on a variety of ordinary subjects due to being an AI. For example, she doesn't know where milk comes from (she mentions that she knows how babies are made, though). She doesn't really understand how romance or love works, and is very curious about it. She also feels a bit uncomfortable around animals, because they're unpredictable and feel warm when touched, which is "a bit scary" in her opinion. She is occasionally a bit playful and tries to make jokes or play little pranks on others, though they're a bit weird and sometimes borderline creepy.

Chiaki usually ends her sentences with a negative note even though she actually means to compliment someone or cheering someone, such as "...I think", or "Maybe...". Those around her once said that sometimes they wishes that she would end her positive sentence on a positive note. However, she truly does care about and wants to protect everyone. She dislikes violence more than anything else and she gets very serious about the topic.
