I want a series that can deliver me the maximum possible amount of anime-ness. What is that anime?

I don’t want to pay for anything, so it needs to be legal to watch on a public service. I’ve had a chat with the Academia and they’ve given me a grant to study anime, but they haven’t approved paywalls. The brummies need to get the most out of this. I’m gonna watch some before bed and I’m so excited. <br><br>I know this is the right place to come, but please don’t take me off the grant I’m enjoying my anime series.
