It’s A Place Further Than The Universe for me, both the first time and the first rewatch. Absolutely phenomenal series.
Also Violet Evergarden. Went from not caring about anime at all to a favorite pastime, and also rediscovering my emotions in the process.
Ghost in the Shell made me see consciousness as something separate from the body that can be moulded and changed over time.
It also made me want to run around and do parkour a lot, so now I have a healthy body. I still need to stretch more though >…>
