So Lee is the latest in a line of bums. Gai's father has been a Genin and an embarrassment to the Village for 20 years. Gai is also confirmed as being unable to use or completely incompetent in the use of Ninjutsu or Genjutsu, which totally debunks the bullshit about him just focusing on Taijutsu. Motherfucker didn't have a choice, he was garbage at everything else. Now Gai has passed on his technique to Lee, the latest failure whose only path to notoriety lies in Taijutsu. Never mind the fact that Gai is about to be raped in a few Chapters before the real action starts.
Oh lol @ his ridiculous looking father. Pornstache & tights.
Actually Gai can use a Summoning jutsu, which is C-ranked and is a space-time ninjutsu that utilizes hand-seals... so it's another bullsh*t or revision from Kishi's side... especially when being unable to use ninjutsu and genjutsu at all, would mean that a person wouldn't be able to even use E-rank jutsu...
A real Colossal Sword, is only Colossal when it is at least 5 times bigger than the thing you pilot:
