PROOF FOR NARUTO BEING UNIVERSAL

1.Fight Against Kaguya:

• It is shown in Kaguya's dimensions that she has stars and planets basically a solar system and beyond they are endless. She can open and close her dimensions so she herself scales above these.
• In the Fight Naruto damaged Kaguya so he can be scaled above solar, and since Kaguya's dimensions are endless, he can be scaled to universal as well.
• The ten tails is scaled to planetary according to statements and Naruto scales much higher than that so planetary is completely wrong.
• Shibai himself is universal and he will eventually fight the boruto characters who will chain scale to Naruto.
