The Immortal Never Bows to a Little Girl

A note beforehand: this is a crossover story, a crossover story. Here's the blurb:

You... want to understand the meaning of life?

You... want to gain tremendous power?

You... are you really willing to do it?

You... are you willing to pay the price?

You... have you eaten?

Hey, bro... want a disc?

...Oh, wait, wrong one. This is women's clothing...

The long river of fate stretches on.

There are immortals who battle against time.
