Jin Narumi is a tough fighter with a lot of speed but that’s not going to be nearly enough to defeat Pegasus Tenma. Tenma is faster than Jin and his attacks are certainly a lot stronger. Mix in the fact that Jin’s stamina seems very unimpressive and he’s going to be in for a very rough time here. He just doesn’t have enough energy to take Tenma down for the count. Pegasus Tenma wins.
Jin Narumi is a powerful shinobi who specializes in lightning based attacks. His strikes are very fast and difficult to counter. The One Above All may be cosmic in nature but that’s still not going to be good enough here. He will quickly falter against Jin’s power since the guy has no real attacks to use that would affect Jin. That means that the One Above All is behind the 8 ball right out of the jump. Jin Narumi wins.
