Tsunade vs Natsu Dragnil

The guy could not find a girl all his life, because his heart was occupied by a girl from the anime, her forms completely absorbed the mind of a young male. The life of our main character flew through time while he was chained to the sofa watching a mature blonde. Such a life completely suited him, but there are no immortal people on earth. So what happens in the case of the death of such non-typical personalities... The main character was not a fool, even knowing that fools are lucky ps. Happy
