Gotta watch one of the OVAs before you watch S3 EP 1 if you want to fully understand some of the flash backs. S2 OVA 2 specifically.
Edit: watched ep 1 of UQ Holder. Mahou Sensei Negima universe set 80 years in the future. Technically shounen, but it did spook me with some violence that is definitely not pg-13. Not bad though, I'll stick with it for now.
