Like I said, anything like the topic of this thread would be a hat on a hat. He’s already chasing his father’s back, what impact would it really have for him to also live up to the Montblanc name (which isn’t exactly respected in the OP world)?
Well think about it. Montblanc Noland wasn't a liar, but went down in history known as one. Usopp is a liar, but everything he lies about ends up coming true, so in essence he actually isn't a liar.
Montblanc Cricket wanted to restore the Montblanc name and prove his ancestors innocence. If
Montblanc Usopp the liar, is actually recognized as someone who technically never lies, and becomes known throughout the World as such, then by EoS, the Montblanc name is restored. I mean, we can ever take it one step further and say that's what Yasopp as been trying to do, but he will fail where his son succeeds.
I'm more partial to Usopp being a D but would not be opposed to that ^ at all. The only thing that really throws it off, is how would Usopp not know what his own last name is this entire time. Unless he only knows Bachina's last name, and she never told him his fathers last name or vice versa.
