Keiji Inafune will make an appearance in Neptunia V as… a flying battleship. I think this is supposed to be a pun on his last name since the second character in Inafune’s last name could be read is "ship". Literally, it’s an Ina-ship.
Former Xbox Mission Division spokesperson Izawa is named as the "Summons Division Manager" in Neptunia V.
Compile Heart will release Neptunia V for PlayStation 3 this summer.
