Tsukasa Fujii

Tsukasa Fujii (藤井 司) is one of Taki's friends in high school. He is often concerned about Taki whenever Mitsuha embodies him.

When Taki was in his original body after the first few times him and Mitsuha switched, he called him cute, his face blushing ever so slightly.

At the end of the film, he is seen wearing a wedding ring. It is implied he is engaged to Miki Okudera. This is possible, as in one scene, he asked if Miki smoked, showing a hint of interest in her.
