Plenty of shonen anime series draw inspiration from the best works in previous generations, such as the classic shonen "Big Three" following the example of Akira Toriyama's Dragon Ball. More recently, smash-hit shonen series like Jujutsu Kaisen and Demon Slayer drew inspiration from the Big Three in turn. It's easy to see how Demon Slayer borrowed the best ideas from both Naruto and Bleach, such as demon slayers being the next generation of Soul Reapers and Tanjiro's trio taking cues from Team 7 in Naruto.
