Cat's Eye Wiki

"At any rate, we must at least clear Cat's Eye's name." - Sadatsugu Nagaishi

Sadatsugu Nagaishi (永石 定嗣, Nagaishi Sadatsugu) is a secondary character of Cat's Eye series.


He is a trusted friend and confidant to the three Kisugi sisters, and a very good friend of Heinz and his wife. Nagaishi provides detailed information for Cat's Eye's heists and also helps them acquire any hardware and/or other sophisticated equipment they may need that Ai Kisugi cannot provide.

His background is a mystery, but he may have been a member of the Armed Forces as he has some military expertise.
