But I don't know how to pronounce his name.
I guess his name is Hiroshi Koizumi or Koji Koizumi.

in ANN he's hiroshi koizumi so lets go with it for now https://www.animenewsnetwork.cc/encyclopedia/people.php?id=11430
I looked it up later, and as a result, I think "Kouji Koizumi" is the correct reading of the name.
