Tomohiro Nagatsuka (永束 友宏, Nagatsuka Tomohiro) is a supporting character in Koe no Katachi.
He is the first person that talks to Ishida as an equal, and is quick to call him a best friend. He is also the first person to lose the "X", signifying Ishida's trust.
He wears a yellow jumper with a white shirt underneath and a red undershirt. Usually, when he isn't wearing his uniform, he is seen wearing a scarf. At one point, he ends up growing a mustache as a token of good luck for Ishida.
Nagatsuka was the first person that Ishida befriended after six years of isolation. He was the first to have his 'X' on his face peel off, which showed that Ishida trusted him. Ishida happened to see him being bullied by some guy who took his bike from him. Subconsciously, Ishida suggested to the bully to take his bike instead, and as he walked home from school, it finally sank into him that his bike, which originally was his mother's, was permanently stolen. Nagatsuka then returned beaten with his bike, and it turned out that he looked for it and found it on a grassy plain. Ever since then, their friendship started to grow. Nagatsuka and Ishida are now good friends and hang out together, and they are currently creating a movie together.
