what would you do if you were the protagonist of a harem anime?
I would say that I'd just passively ignore that part of the situation, but then I think of School Days. It only had a harem of 2 (if you can even call that a harem) and that guy ended up riding a nice boat down the river styx.
I would probably attempt to force a genre shift. Maybe a comedy, those are safe.
Be good friends with all of them, and tell every girl in secret that she is the chosen one but can't be with her because the other girls will ruin the friendship and all that crap so we can only be lewd in secret.
Aim for harem end.
If it fails ---> Good, I still won
If succes ---> shin sekai no kami
Pick a girl.
See if she's okay with harem end.
If not, tell the other girls to GTFO.
If yes, pick 1-2 other girls, see if they're okay with harem.
If yes, they're in.
If they're not, GTFO, along with all the other girls.
I just hope there's no risk to get axed so that the setting shifts to battle shounen.
Otherwise, guess I'd choose a girl and befriend the others while being clear on my position.
And for a change of pace, finding myself some male friend too.
Wow, was this a boring answer.
Disregard all the useless girls and marry shonobu.
Give crab, bee and cat an especially good beating for cutting their beautiful hair to this short dyke level shit.
