Possible plot

I am greek and recently just about yesterday I started reading the Manga. In any case I have seen a lot of words that are greek in it. Main characters name is Rudo Surebrec Surebrec in reverse means Cerberus which was the mythical 3Head dog like beast protecting the gates to the underworld so that no live can go in neither a dead can go out. That may explain the usage of 3 weapons at a time and also why his ancestor was the undertaker. But other than that Typhoon his rival in the Manga is meant to be the father of Cerberus in greek Mythology. That is kind of strange to me but also is making me thinking how Zolda and Rudo may be blood related from the past.

Any thoughts on that?
