My choices would be: Bleach > Shokugeki > Black Clover > Overlord Most preferably Bleach because it will be very interesting to see mc against or even working with Aizen. Shokugeki is also good because of the nice girls and there's something unique about adding superpowered characters to a world like that which is just based on cooking but with normal people.
1. Overlord, in my opinion this is the best choice because they can get my abilities from game which can help them in my ways. One example being resurrection Magic well I don't think I need to explain it's usefulness. They will need help against 666 which these etc. abilities can provide. They can also relax in this world. They have been running around here and there in previous world. If they want they can even get all the abilities and magic this game has to offer by hacking. But I would prefer it if they do it at the end of the game just before they enter new world. 2. Campione or Knights & Magic, well these worlds aren't used much and I am getting bored because other worlds are getting repetitive. So, I want something new. I tried writing my own fanfic but I suck at it so I didn't continue writing it.
