Recommendations?

The beginning after the end is also rly good

Well, I'm into characer growth but not particular the op part. Usually that is where I drop the series. The things I recommend could be completely different than what you wanted to read, sorry about this. I've used isekai a lot, but idk if I use the term correctly but oh well.
Have added some some recs based on emotional character growth however. Hope it's to your liking!

Shounen-ish things... (I am very bad in genre division, sry)
- Beastars!
coming of age, animal society, furry-ish I guess?
- Psyren
standard action-adventure shonen with growth in abiities. I hope this gets an anime sometime...
- Kumo desu ga, nani ga?
