Saki suffers from severe amnesia. She is not able to keep memories for a long time, so she writes down the names of all her friends and the events that happened to her. If she likes someone very much, she can sometimes draw drawings with that person and write about her. Saki is straightforward, says what she thinks, so sometimes she can say an insult to another person without even realizing it, and then not understanding why he was offended. She can often seem uninterested in communication or certain situations, easily distracted, and take a long time to respond in order to formulate a thought (or just in her head)
