Hiromu Takahashi needs splitting; my attempt to was rejected

The current Hiromu Takahashi (I) on IMDb amalgamates credits from two different people. One is a burly pro wrestler; one is a thin and androgenous actor. They are obviously not the same person from appearance alone, and also have different spellings in Japanese and different dates of birth.

Hiromu Takahashi (高橋ヒロム), aka Kamaitachi, is a pro wrestler born on 4 December 1989. Most of the credits are for this person (and perhaps they should all be "Himself" credits, not acting ones, though I'm not versed in what the consensus is for pro wrestling). His entry on allcinema is here and his entry on Eiga.com is here.

Hiromu Takahashi (高橋ひろ無) is an actor born on 5 January 1985. This is the one who is credited in the cast of Candy Boys, not the wrestler. His entry on allcinema is here and his entry on Eiga.com is here. This credit should instead be attributed to Hiromu Takahashi (II).

I tried in the update 210108-030820-085000 to remove Hiromu Takahashi (I) from the cast list of Candy Boys and replace him with Hiromu Takahashi (II), but this part of my submission was declined, with IMDb citing lack of evidence, though I had provided the addresses of their separate entries on allcinema as evidence.

Rather than trying again that way I'm giving the evidence and explanation here instead, as the difference is clearest when I can show the Japanese spellings, so I thought this might be more likely to get results.
