Arcane perfection of each character was due to Naoki Urasawa.

Naoki Urasawa's way of expressing his story is one that is definitely unique, especially with the channeling of mystery and that wasn't lost on Arcane's Studio either. The first season easily scored a 100% on Rotten Tomatoes and with the way each character was handled and portrayed, no one complained.
In one season, Arcane has proven what it means to successfully nail animated adaptations of video games. It was one of the few that did and only then the list grew more and more with Fallout and The Last of Us entering the picture. While it still has the benefit of an animated medium, there was a lot of depth to it that made it as good as anything, regardless of form.
In an interview with Crunchyroll, Studio Fortiche's co-founder, Pascal Charrue, talked about all the anime inspirations he and the studio took when making seasons 1 and 2 of Arcane. For a series that has so much depth in not only its main characters but also in its supporting characters, there must have been a whole lot of material that became their guide.
