Hiroshi Tanabe's Japanese Wikipedia article says that he writes lyrics under this name, but I couldn't find anything directly confirming it. Believable, though.
- His homepage profile and Twitter bio mention he does lyrics, but he doesn't appear to have ever written lyrics under his real name, so an alias makes sense.
- Wonder Fruit and Tanabe work together a lot. I think every single games listed in Wonder Fruit's Wikipedia article appear on Tanabe's works list too.
