バカは死ななきゃ治らないっ！

This is the debut work for doujin circle integral. Kazuhiko was run over by a truck on his first day of school. However, when he arrived in heaven, God told him that it’d be a problem if he was dead, and sent him back to Earth. He didn’t understand what happened, but he went to his classroom and found that he had to repeat the year. His osananajimi Kanade became his senpai, and a Russian serial killer Elena transferred into his class.

“Whoops, I added ********** instead of salt >_<”
“Idiots can’t be cured unless they die!”

Is there a cure for possibly the most stupid person in the world? What will his destiny be after achieving immortality? Even God doesn’t know!

Hau~ Omochikaeri!
