New Anime Suggestion Box (Patreon)

By this time next week I'll be done recording Naruto. I won't be doing the sequel series any time soon, so I need a new show to replace it on the Anime Youtube Channel.  I'm looking for suggestions, but keeping in mind the following things:

1) My target for doing the Naruto sequel series is next summer/fall, so I want something that is between 100 and 300 episodes long.

2) It has to be popular.

3) I'd prefer it be something I can get on either HBO Max or Netflix, but this isn't a dealbreaker.

4) Don't suggest My Hero Academia because that's coming here in a few weeks.
