There is no such thing as a perfect katakana in this world. For Japanese people, it's like slang. So I think it's incredibly amazing that Chris Jericho can read katakana. There's nothing wrong with your translation either.

Thanks! I added the Japanese names this time after finding a more accurate katakana translator, but let me know if you find any issues :)

Great work as always. It's also nice that it always has Japanese language capability.
