Not like that. Pairings mean nothing. I mean that, from an in universe perspective, Ichigo X Orihime is responsible for the destruction of everything.
All we've seen of Kazui Kurosaki was him putting his hand in a random swirly hole, and that somehow killing Yhwach.
Then he meets Ichika, and says "I'm a Shinigami!".
The important thing here is destroying Yhwach. Yhwach was the Soul King, the Lynchpin of existence. By destroying him, Kazui has effectively destroyed everything. That's why Bleach is over. There's nothing more to write. The universe is gone, and everyone is dead.
Well done Kazui.
