An engineering sophomore, preparing for his project, suddenly collapses from a heart attack and dies. When he reopens his eyes, his vision blurry, he is shocked to see a towering human giant above him. To his astonishment, the giant was wearing a headband with a leaf like symbol- the same as the ones from the anime Naruto that he had binge watched just days before his death.(MC was a BLEACH fanatic)
