Well that doesnt look like the japanese version, but rather the dazedTL, which really isnt a guarantee that its like that in the actual japanese language version. (also p much all comments on that page are for the mtled version and doesnt matter how good a mtl is , errors may happen).
Although I have used this version as an example, in the end it is the Japanese version translated by Daze, and the otaku version has the same black screen and there are no updates and no one has complained on Steam.
also in ci-en bugs they don't make any reference to the black screen so it's part of the game I know it looks ugly but it's what it is, unlike Daze, the companies that localize Japanese games work with the latest versions. (With this I am not saying that the translated versions do not have bugs, they also have many bugs too) There are probably other new bugs in the otaku plan not related to those of the Japanese version.
Since you look at everything through the prism of doubt, I understand the distrust you have towards companies that localize japanese games, here is the bug list in ci-en from the Japanese version, post from Sep/3 to Sep/21 are the list of all errors and the game had a ton of bugs .
