Q: Shigure? You mean Shigure Miyamoto?!
A: Yes, Satoshi Taijiri had Shigure as a mentor, and in honor, named Satoshi's first rival Shigure.
Q: Why the name Kenji?!
A: 'Cause one of the dudes that work in Nintendo is named Kenji, just like Satoshi, Shigeru (i think), and Hiroshi...but is there a Takeshi? I dunno...probably. They usually use the names of some people in the Nintendo company. - Krazykat
