I can't argue with the power of his will, and the fact that he gave up his arm, back then.

But i still think, things happen too fast. I mean if it continues like this, it won't take more than 10 years for Issei to reach the powerlevel to rule the whole freakin' universe. Then what's the point of living so long, if you achieve everything in so little time. Even the fun times with the girls can become boring after 100-150 years, if you do it 10-15 times a day, which i suspect will happen after he settles down.
