The best way to do that would be through Discord: https://discord.com/invite/vuEgcR4vyk
You can find the dev team there.
It's more like looking for an opportunity, your story has an impressive if not terrific writing and I am someone who has played several games similar to this one and I always read thoroughly enough. Some of the writing is great, some mediocre and the rest rely on google translate... 'A LOT'. So I wanted to ask for an opportunity to communicate with the devs and ask if they have any connections or people interested in proof readers. I just like stories a lot and your game's story feels so real, the writing feels so natural, and I wanted to keep aiding in maintaining the text as amazing as I possibly can.
I'm not sure what you mean by usual job requests. You may try this discord channel if you're looking for a visual novel related job:
