There are actually 25 episodes in season 1. Also since you always check I don’t think you’ll miss it but there’s an after credit scene in episode 24 so I thought I’d say it just in case. Also on Crunchyroll there’s an OVA called “Lev appears” that takes place between season 1 and 2. While I don’t think it’s absolutely necessary to watch, it does introduce a fairly relevant character so I figured I’d also mention that. You can figure things out well enough without seeing it but it gives a good amount of context for later. Looking forward to the end of the season, good stuff as always!!
