明察秋毫
Meaning
An observational acuity so fine it can pick out the thin autumn hair of an animal — perception that misses nothing.
極めて細かなことまで見抜く、鋭く優れた観察眼。
The Kyojuro Rengoku moment
罠や鬼の気配を的確に察知する洞察力 — Rengoku reads the geometry of the Mugen Train carriages, identifies the dream-trap creatures by breathing pattern, and tracks Akaza's position by air-pressure shift alone.
Why it fits Kyojuro Rengoku
Hashira-level perception is not super-power but trained attention; the manga repeatedly shows Rengoku reading rooms and battlefields a beat ahead of everyone else. Meisatsu-shūgō is the classical Chinese frame for that quality — sight so fine it picks out the new autumn down on an animal.
