I just started watching Galaxy Express 999. So I'm not sure what episode this was based on yet. Anyone know? I'd like to put the episodes on these hentai so people can more easily know which episode to watch to get more of the story, or which hentai they should look at after the episode.

The show itself is quite a blast from the past. Although the logic of the stories is pretty messy, the visuals and big ideas are stunning. And Maetel is a delight (even when she doesn't take off her clothes). I was really happy to see how much hentai there is of her out there. Sadly, much of it isn't translated, but that's OK. It'll give me something fun to work on long term.

Also, it was great working on this comic from Aratamaru Sensei. It really feels like his work is professional grade so I'm looking forward to more. Although he only has a handful of Maetel works available on e-hentai, there are probably 10 or so that are out there waiting for someone to bring them over. (Nighthead Maetel 1-8 and some others like Nighthead Zero 1-3.)

Thanks for the share
Maetel really lost a chance to make a comment on the lines of "I'm still kinda in heat" on the last page...
