I actually went from a 7 pro to a 9 pro, and while Idk if its small enough for you it is a massive change in usability for me. I disliked the 7 it was usable but annoying at times to reach stuff I almost never have that issue with the 9 pro.

Just a tip for Tokyo Ghoul the anime is alright but very very bad compared to the manga. The anime made some very stupid changes for the story and failed to capture much of the tone of the manga.
