Thank you so much for the reply, Reaper!
I'm giving you free rein here, so don't worry about the workload. We'll accommodate as much as we can, and let you know if anything is beyond our abilities.
And we can definitely add pronouns and squeeze in a bio for the side characters somewhere. As you suggested we could put the additional info behind a spoiler tag and let players actively decide if they want to see it or not.
PS. Fanservice is always on the house around here, you know that (¬‿¬ )
