Generally speaking, the strict appliance of real world physics laws in a fantasy anime is kind of off place in the first instance.

"blackholes are not infinite. eventually it reaches critical mass in which it discharges all of its contents. we haven't been able to see this happen yet, but it is an accepted theory. (i think.) so, a very small blackhole would be able to last long enough to rip anything to shreds, but not long enough to last more than a few milliseconds."

There is a mistake in that - black holes do emit radiation of energy, but that is due to their compressing matter and thereby gaining mass. They lose energy, yes, but they constantly gain mass, as long as there is mass around them which they attract. As such there is no critical mass for black holes before they explode. The process of growing mass is irreversible in a black hole, and it also is limited only by the amount of mass within its event horizon.
