How does Kazuma actually die in the beginning of the anime? In the beginning of episode 1 of the anime, Aqua makes fun of Kazuma for how he died. She then says that she has, "Well... I've vented enough stress for now," before continuing her explanation of the choices that Kazuma has in the afterlife.

Is this a joke or did Kazuma really die from shock of possibly being run over by a truck?


   I hope he died of shock.
Kazuma died because of heart attack.

Actually, the girl will survive even if Kazuma didn't save her. The vehicle that was moving towards the girl was just a slow tractor. After he pushed the girl, Kazuma died because of heart attack, he thought it was a truck and he was scared to death.
