The connecting record
shownBleach · 2016
Ichigo Kurosaki killed Yhwach in Bleach.
Aizen held him, Uryu's arrow landed first — and the ending leaves the rest open
What each of them is ranked on
The killer · Ichigo Kurosaki · rank 2
Substitute Shinigami — manga
He cuts Yhwach in half, which is the result the entire final arc is built toward and the only clean finish anybody gets against the tier above. It is second rather than first because of what it took to arrange: a blade reforged twice, a Quincy carrying stolen power, and the man who spent a hundred chapters as the previous villain holding the target still. Ichigo lands the blow. He does not do it alone and the arc never pretends he did.

Bisects Yhwach with his reforged Bankai. — 2016

Defeats Ulquiorra Cifer in a transformed Hollow state. — 2009
The victim · Yhwach · rank 1
The Father of the Quincy — manga
He takes the Soul King out of the structure of the world and installs himself in the gap, which is the largest completed act anybody in this franchise manages. Before that he goes through a Gotei captain-commander who has been the strongest thing in Soul Society for a thousand years. His ability to choose which future occurs is the part to be careful with — it is explained far more often than it is demonstrated, and the explanations are doing work the panels do not.

What this does not settle
One death in one work. It is the only place the record puts these two in the same room, and it is evidence about that meeting and nothing wider — not a general matchup, not a rematch, and not a ranking of its own.
The ladder above it is argued from everything either of them has been shown doing; this page is argued from one citation.
Where the two disagree, the disagreement is the point, and it stays visible rather than being resolved by whichever of them happens to be on this page.
