This ability allows Naruto to overwhelm his opponents with multiple Rasengans from his shadow clones. **

This jutsu showcases Boruto's creativity and skill as a ninja, as he adds his own twist to the traditional Rasengan technique. **

Additionally, Sasuke's character arc and development take him in a different direction from Naruto, leading him to pursue his own path and abilities rather than learning the Rasengan. **
