I misunderstood the pronounciation of "Cyber Stein", which is a powerful monster card in Yu-Gi-Oh! Trading Card Game. The name is derived from Frankenstein. Although the name of in Japanese is デビルフランケン, the word "Devil" is not preferred because of religious code.

I call stein /stein/ because of its spelling. But, most native spekers pronounce /stain/! If you do not know the origin of the name, you will misunderstand the pronunciation.
