I actually watched Diva as it aired just like you. Had no idea what was going on, don't remember anything except for a couple of the waifus. That was.... God damn 2021. Sheesh.
Thanks for the guide though. I sometimes feel like AVGN when he rants about inconsistent movie titles when I see some anime season names.
