We know Yubaba steals most of the kanji of each employee's name to have some control over them, leaving them with one symbol of their original name. In the manga series Fruits Basket, the girl Isuzu Sohma is nicknamed "Rin" because one of her Japanese name's kanji symbols creates this name when alone.

So could Lin's/Rin's real name have been "Isuzu"? How big of a chance is there for this?
