I really wanted to try this new AI manga translation tool:
https://github.com/zyddnys/manga-image-translator

It is also hosted online of anyone wants to try few images:
https://cotrans.touhou.ai/

Used command:
python -m manga_translator --upscaler waifu2x --format jpg --upscale-ratio 2 -v --mode batch --use-cuda --translator=sugoi -l ENG -i "Z:PATH_TO_MANGA_FOLDER"

Images are 2x upscaled from the resampled version of the original gallery. So we can render the english font readably. (Ye, im a cheapo, I didn't download the original files..)

Translations are also automatically impainted into the image by the tool. Aside from the command, nothing is done manually. This is the first automatic AI assisted tool i've seen, that can actually translate manga without any manual work in most cases... well it's readable and the text makes sense.

Author of this tool also plans to do an editor, so it will presumably be easy to do manual corrections.

Also, I foolishly set the generated output format to .png, but it has also an option for jpg output, which is roughly 1/2 of the size. Whole translation took ~32 mins.
