Why did you set the resolution (2880 x 1920)? It's so inconvenient

The screen ratio is 2880 x 1920. Why is it like this?

You can turn this off, when clicking the button in the down right corner of the player.

Best part about AI is that it’ll turn Queen Bee into Bunnywalker and it’ll turn Bunnywalker into Studio Ghibli. That’s the quality level increase in frame rate and animation detail it’ll do in the next 3-6 MONTHS. It’s gonna be wild to see all these slide shows suddenly turn into actual movies.

Sorry about the long text. Please hold your phone sideways to read it easier. Some people think it’ll be like Star Trek or the Jetsons. Others think it’ll be like Terminator or Dune. I like to think it’ll be closer to Futurama. Mix of good, bad, and a whole lot of strange. That said, I’ve been dreaming of some sort of computer tech that could take the curved lines of manga and start animating them so we could get 1:1 anime of the Japanese manga and American comics. We’re now going to get something so much more powerful. It’ll be used to produce 99% garbage but the remaining 1% will be absolutely masterpiece God-tier quality hentai that’ll make you believe in God again. Imagine hentai that had the same animation quality as Akira, Ghost in the Shell, Princess Mononoke, etc. Imagine all of your favorite manga and hentai doujinshi fanfiction all the American fanfiction Rule34 suddenly getting that treatment. It almost makes me cry tears of joy. At least one of my childhood dreams is finally coming true. People are going to fall in love with 2D style animation all over again and it’ll ironically be because of AI. This will also foster enormous appreciation for the old vintage animation because it’s not just the source material training data it was all so painstakingly laboriously done by hand and criminally under appreciated.

I hope so, buuuutttt billions of evolution for simping for a 2D girl? That's a little weird, i know bro we are discussing this on a hentai site but i hope you get the point. But hey At least I'll be happy to see berserk in 4K.

They’ll start in 2D but then the AI will go into SexBots and that’s how we make Hentai Harems real for Weebs IRL. We are definitely getting our dicks sucked in the next 12-18 months.

Yeah, this is disappointing. And here I thought the bonus ending was gonna get animated, instead it's only shown in the credits with no motion nor dialogue.

I think it was loaded with the wrong format, because it is not 1920x1080 but 1920x1280.

No the format is fine, the video is anamorphic 16:9 so it will be stretched to fit

What a way to ruin an amazing manga. Queen Bee is a disgrace to the hentai community.

Theyre doing adaptations here and there that lead to the doujins sales, they have a part.
