Shinichi also gradually loses the ability to empathise with others and even his ability to cry. This is made worse by the fact that Migi often threatens to kill anyone who finds out about him, and so he is unable to tell people the truth about what has happened to him. This change in his behavior starts to worry those around him, especially Satomi Murano, who often wonders if it's really he, or someone else entirely. His bond with Migi becomes stronger and he occasionally begins to think like a parasite, as how he described a dead dog's body as 'a lump of dog-shaped meat' (Migi even notes that that sounds exactly like something he would say). However, as a side-effect of fusing with Migi, Shinichi becomes somewhat distant and unsympathetic. However, he is not immune to anger, as he also shows a very vengeful side when he attempts to track down and kill the Parasite who killed his mother and took over her body, saying that the thought of such a being walking around freely makes his blood boil. His father even asks him outright if he's made of steel. He becomes very calm and cool-headed, taking horrific events in stride without so much as flinching, a sharp contrast to his former awkward, timid self. Nevertheless, the two are shown to be able to cooperate in a crisis, and work well together against hostile Parasites.Īfter Nobuko Izumi's (Shinichi's mother) death and his subsequent rebuild by Migi, Shinichi gains significant resolve and resilience and is willing to risk his own life to protect his friends, family, and the public from harm. He considers human life precious and is disgusted by the Parasites killing humans senselessly, though Migi speculates that this is because it's his species that's being eaten, and points out humans eat many different lifeforms in order to survive, and that, in a way, that makes them even worse than Parasites. When Migi proposes that they work together by "cooperating and coexisting", Shinichi initially shows great reluctance, scared of both working with an alien symbiote and the thought of killing in order to survive.

He also overcomes his fear of bugs, due to Parasites being much scarier, much to the confusion of his mother. Shinichi then becomes more aware of his surroundings and excels in sports like basketball. All of that starts to change after being formally introduced to and acquainted with Migi, though he is understandably horrified at first.

However, he is also considered a bit of a pushover and a wimp, due to his awkwardness and paralyzing fear of bugs. Initially, Shinichi is a thoughtful and nice person who cares a great deal for those around him.

Some time during the one-year timeskip, he reverts back to his original hairstyle. He claims to like the new look because it "looks more balanced" - symbolizing that he is no longer merely a human, and also referring to his newfound calmness and mental fortitude.Īfter a confrontation with Gotou, he gains a new smaller scar over his right eye. After Chapter 17 of the manga, or Episode 7 of the anime, Shinichi begins spiking his fringe upwards. He becomes more muscular, and in the anime, he removes his glasses, since he no longer needs them. This repeats throughout the manga.Īfter Chapter 12 of the manga, or Episode 5 of the anime, Izumi is left with a large scar on the center of his chest and back. For example, when he first meets Migi, he has a T-shirt that says "Misery Confusion". He also tends to wear T-shirts with strangely appropriate words written on them. He usually wears his school uniform, consisting of a white shirt and a blue blazer, while in the manga he wears a Gakuran, an all-black, old-style Japanese school uniform, with a white shirt underneath. In the anime, his hair and eyes are brown, and he initially wears large square-rimmed glasses. In the manga he has short black hair and brown eyes, and is mentioned to have a somewhat feminine facial structure. Shinichi is of average height with a small build.
