Four-Character Idiom · Combat & Force · Kyojuro Rengoku
獅子奮迅
Meaning
The unstoppable momentum of a lion springing into action — overwhelming force unleashed all at once.
獅子が奮い立つように、凄まじい勢いで奮闘すること。
The Kyojuro Rengoku moment
猗窩座との極限の死闘における猛攻 — Half-disembowelled, Rengoku still drives his Ninth Form against Akaza with the focused fury of a cornered apex predator.
Why it fits Kyojuro Rengoku
The Rengoku vs Akaza fight is the canonical shishi-funjin sequence in modern manga. Lethally wounded, Rengoku fights faster and harder, the way the idiom literally describes — a lion springing up rather than going down.
Cultural note
Origin in classical / Buddhist / Confucian tradition
The lion (獅子) carries Buddhist resonance: the Buddha's teaching is the "lion's roar" (獅子吼) that scatters wrong views.
