Openings: Both are bangers! I was so hyped to see an artist I've been following for a while (Eve) be part of it, he deserves so much more love! Vivid vice also grew on me and I'm going to check out Who-ya's discography eventually :>
Not too familiar with visuals from a critical standpoint but I really love the intricate things that change in the first OP as the story progressed. And also i was one of those who were tricked by the opening with junpei, i thought he was going to be in jujutsu high ;;
Animation: as mentioned, not a huge critic with animation but it looks smooth and the battles look stunning!! :D I love how the more comedic and cartoony parts blend in as well
Story: Even as someone who's not the most exposed to battle shounen, I feel like the story is pretty okay and not much has happened so far? (While things have happened, they often felt like appetizers over main courses if that makes sense) That said the first season (I'm an anime-only watcher) feels a lot like a setup and buildup of amazing things to come in future!
Characters: I'm in love with the main cast. I can't help myself. They're all really charming :D That said, I really hope there's more to them than what we've given so far. It feels like there's so much more to explore about their characterizations and ideals, and I look forward to growing to love them even more from there
Ending: EDs?? I love both too, both the songs themselves and the way they're presented. The second one in particular felt really bittersweet. :'))
