Shintaro Kisaragi

Shintaro Kisaragi (如月 伸太郎 Kisaragi Shintarō) / Shintaro (シンタロー Shintarō) is the main protagonist of the series. A digital girl named Ene that lives inside his computer causes him to go outside for the first time in two years, where he meets the Mekakushi Dan and becomes its seventh member.

Shintaro became a shut-in NEET after his three only friends all died on the same day. He blames himself primarily for Ayano's suicide due to several incidents and his behavior before her death.

Appearance
Shintaro is a young man with short black hair and narrow, dark brown eyes. His character designer, Sidu, has stated that his eyes are drawn with their unique shape because "drawing them normally would make him look like any other light novel protagonist" and she wanted to make him look "uncool". His hair is supposed to be not voluminous and short near the back of his neck. When illustrated by Sidu, his eyelids have epicanthic folds.

In most Routes, including Route 1 of Losstime Memory, he wears a red track jacket that has white stripes on its sleeves over a black v-neck shirt and light brown pants. Shintaro claims that he wears the red jacket because a "female friend" of his said it looked good on him. At home, he normally wears a pair of red slippers with gray socks. Outside, he wears a pair of red sneakers with a black trim. In the Novel Route, he wears his jacket zipped up to the collar on August 14th, including during the terrorist incident at the mall. In the manga and short film, he wears the ends of the sleeves of his jacket up to his elbows. He also wears this jacket during his visit to Takane's Headphone Actor booth in the manga and novels.

In Route XX and in a scene of the anime, he wears a black pullover hoodie with gray pants and remains barefoot.

Back in middle school, he normally wore a common black gakuran uniform with a white shirt underneath.

In Summertime Record and Lost Day Hour's manga depiction, Shintaro wears his usual red jacket, a white shirt, black pants and red shoes that have a white trim. In the short film Kagerou Daze -in a day's-, he wears his usual jacket over a white t-shirt that has a large red "7." on its center, dark brown pants, and red shoes that have black soles.

Personality
Shintaro is a young man with an IQ of 168. Thanks to his high intelligence and likely the latent use of his eye ability, Retaining Eyes, he has perfect photographic memory. However, likely due to subconscious memories of past Routes, he finds that everything in the world is predictable and has obvious answers, and he would get perfect scores on his exams and even games he has not played before. Because of this, Shintaro grew up with an apathetic personality. In middle school, he was openly selfish and arrogant and showed signs of depression. It is implied that his loneliness prior to meeting Ayano Tateyama is a significant contributing factor to his depression and also his personality.

During his first year in high school, he became close friends with his upperclassman Haruka Kokonose, and they would spend time with Ayano and Takane Enomoto often. He becomes distraught after learning about Haruka's imminent death by his illness. On the night of August 15th of that year, he meets Ayano, whom he doesn't know is actually Kano using his eye ability. Kano tells him that "everything is your fault". The next day, he learns about Ayano, Haruka and Takane's deaths, and afterwards, devastated, he drops out of school and becomes a NEET. He also does not go outside for two years until the present plot. A year before the present plot, he downloads Ene from an email from an unknown sender and is thereupon unable to remove her from his computer.

In Route XX of the Music Route, he is still depressed and refuses to let go of his guilt over Ayano. He forces himself to remember Ayano and is afraid of forgetting her, and because of this he purposely avoids contact with people and refused to move forward. When Ene wakes him from a dream about her, he kills her before stabbing himself in the throat with a pair of scissors.

In other Routes where he is wearing his red jacket, he has changed drastically. Since he is actually very weak, Ene's presence was so overwhelming that he could not do anything but accept her. He has also become hopelessly addicted to the internet and even states that he would die without it. He is very fidgety and gets scared easily by horror themes and social situations. However, he often shows courage when he needs to, even against imminent dangers such as a hand around his throat. His intelligence also allows him to create complex plans with likely good results even when stressed.

Despite his past and usual reluctance, he quickly befriends the Mekakushi Dan in most Routes. He shows sympathy towards Hibiya Amamiya when he sees him distressed over losing Hiyori Asahina and usually gets along well with Konoha. He also does not hesitate to risk his own life to protect those that he cares about, especially his younger sister, Momo Kisaragi.

In Manga Route 2, Shintaro does not meet Ayano in middle school and instead closely befriends Haruka while he was staying in the hospital. He becomes a NEET after learning about Haruka's death. Afterwards, he tells Momo that he feels that the world "betrayed" him because he made a friend and blames himself for Haruka's death.

Eye Ability

 * Retaining Eyes (目に焼き付ける Me ni Yakitsukeru): Shintaro's eye ability, given to him by Marry after promising long ago to "never forget this Tragedy", allows him to remember everything he sees. Unlike others, he does not visit the Kagerou Daze each Route to gain this ability and instead has it since before birth. When his ability is fully activated, he can remember events of past Routes and directly speak with the Snake of Retaining Eyes. In Manga Route 2, Ayano Tateyama trades her life to become the snake for this ability.
