Mob
Choked unconscious by Teru, he broke Teru's barrier and lifted the wreck of Black Vinegar Middle School above the clouds; awake again at 100% Sadness, he put the building back. Inside Mogami's mindscape, with his mental body destroyed, he erased the spirit army and the world it lived in. Hit by a car on his way to confess to Tsubomi, he walked across Seasoning City as a storm while Teru, Sho and Toichiro Suzuki tried to stop him, absorbed the blast father and son fired together, and arrived to be turned down.

The strongest psychic of his century, dead twenty-five years
Every fight he is known for took place inside a world he authored. In Minori Asagiri's body he let Mob believe his blasts were landing, took his powers away, and ran him through six months of bullying in the thirty minutes that passed outside. Mob at 100% Courage cut down his spirit army and was still broken by the spirits that came loose, and only ???% ended it. His one showing in the open came twenty chapters later, when a Claw soldier broke Matsuo's flask: he drained the soldiers' life, built a body from Minegishi's plants, and let Minegishi go because Mob asked. A fight on rules he set and a fight he chose to walk away from leave nothing to place him by.

What this does not settle
One fight in one work. It is the only result the record gives between these two, 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.
