Completely unshaken, whatever is happening. Formal and strong.

What a Japanese person actually thinks
Dignified and slightly old-fashioned. The register of describing a general or a surgeon. Reads as real self-possession rather than as coolness.

Meaning

Literally: calm + as-one-is
Actually: Remaining exactly yourself under pressure — not reacting, not panicking, not performing calm but simply being it.
