If there are no official publicly open records, then it would make sense Kikuru doesn't necessarily have any information those anons would find. A fan would have needed to create the records, after all. Since the dude isn't exactly a regular visitor at TV stations, no broadcaster would do it for him, to promote their own programs.
Kikuru himself wants to retire, so as far as he's personally concerned, he ought to be happy he's not more famous. If he's unknown to most, nobody would protest even if he retires and no journalists would come to interview him, asking why he's retiring.
