So it turns out, whenever I try changing the name of the characters or anything else that would require the keyboard, the keyboard just won't show up and I don't know what to do about it.
That's a device issue, happens with some devices, even outside gacha, happens on my tablet, just give it a few mins to load up and if it doesn't try again, if it just doesn't, restart device fully and check for updates on anything else, try in other apps too
Happens to me too, usually you just have to reopen the app,I think it happens when you rotate the screen or get out of the app tab for a while and go back in
