One last point before I head to sleep. 6ou said limited durability. And I thought they were of a limited durability as well, but then I noticed that her tentacles take a ton of punishment. Being stepped on, being forced through stone, being tugged, bit, scratched. And never break

And yes, you can say "well, [i]chizuru[/i] can rip through Ikas tentacles with her bare hands"

And to that I say, yes chizuru can. Chizuru can also cause miniature earthquakes simply with the force of the wind beneath her hand being forced downward at such a rate that the rock cant take it. She doesn't even have to touch the ground to do it. She moves at least 10000x faster then apocalypse. And she's chizuru. So, saying chizuru can break Ikas tentacles is like saying you can kill a fly by dropping a planet on it.
