Infinite Everything Is for the Sake of Death

Nani? Got a system? Can it be transmitted infinitely across various movie, animation, and novel worlds? But please tell me, why do you have to die to travel through time? They're all so damn dead, what's the point of traveling through time? Ding: Please jump down as soon as possible. If you see anything, just aim at the stone thirty floors down... This is a deceptive story about constantly dying in various worlds in order to travel through time... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
