Ikuo Takabayashi

Ikuo Takabayashi is the member of 9th Grade Class 3 of Yomiyama North Middle School.

Personality
Probably due to his heart condition, he's very quiet, but he seems to get along well with the rest of the class. He reveals in the first episode that he'd wish to run, but because of his medical condition he can't. He also shows great courage when he offers himself to tell the truth to Sakakibara, probably knowing what was to happen to him. That is, his death.

Appearance
He has brown hair and eyes, as well as freckles in the anime. He never appeared in the manga, and his name is only mentioned once. For his school uniform, he wears a white shirt and a blue vest instead of blazer.

Plot
He had been diagnosed with a heart condition since birth. This causes him to always be absent from school.

In Episode Build Limbs, he's willing to tell the truth to Sakakibara, but suddenly his heart condition causes him to fall over and he dies. He's one of the "Deaths of June".
