Isana Tataradani (Japanese: 鈩谷 鯨, Tataradani Isana) is a fictional Japanese OC character.
Her surname, 鈩谷 (たたらだに, Tataradani) is a given and uncommonly used Japanese family name. It literally means "furnace valley".
Her given name, 鯨 (いさな, Isana), meaning "whale". This is the archaic meaning—the modern reading for that term would be kujira (くじら), and as in use of biological terms, this term is often written in katakana as クジラ.
