Meaning

To enter a conversation with a single sword and go straight to the point — no preamble, no softening, no negotiation about what will be said.

前置きや曖昧さを省き、すぐに本題に入る、あるいは話を断ち切る決断力。

The Kyojuro Rengoku moment

A line Rengoku uses to close an unwanted line of questioning — the dismissal is the entire response.

Why it fits Kyojuro Rengoku

Tantō-chokunyū is normally used of getting to the point; Rengoku uses the same energy in reverse, to end a topic without taking a step into it. Either direction, the move is the same: a single blade, deployed once, and the conversation is over.

Cultural note

Origin in classical / Buddhist / Confucian tradition

A Zen-derived idiom — the seeker who comes to a Zen master with a sharp single question and gets a single sharp answer.
