i guess you dont read the manga as you only just mentioned it , yes its pretty badass but even in the manga we are yet to see the 8th gate , and its like 30 episodes ahead , btw gai will die using the 7th gate
Narutoverse is unpredictable. I am sure there is someone out there who can use the Eight Gate without the consequences or without dying. Maybe Lee or Guy himself.
i think only 3 people knows to open gates
Kakashi- we seen him use the first gate..i think he can open all 8 if not atleast up to 5
Lee- we seen him use up to 5th gate..and kakashi said tht he was a genius with the gates
Guy- ofc he the master lol
i wonder how hard Guy must have trained to keep up with kakashi.. and his always a cheerfull man lol
i love it when he used his summon in midair lol
