Last Names!

[blackmage_nuke]

Since Seymour and Kimahri are refered to as "Seymour Guado" and "Kimahri Ronso" respectively (as well as a bunch of the guado and ronso Blitzball players) Logically everyone elses last names are:

Yuna Human
Wakka Human
Lulu Human
Auron Human
Rikku Human
Tidus Dream (possibly Tidus Aeon)

aye or nay?
genius or nut case?

Seriously though, it seems that humans in this game are distinguished by having only a given name.

I think the Ronsos and Guardos are just reffered to by their species, but do have actual surnames.

I have read in various sorces that Seymour's Last Name is "Solus". If I can find a link, I'll send it.

Auron would be Auron Pyrefly i guess... XD
