You know, all of the names in Phantasy Star II were normal, except for Eusis.  (Rolf)

What kind of name is that?

I did some checking and 'eu' is a prefix that can mean:

1. Good, well, true
2. A derivative of a specified substance.

'Sis', however, is an informal abbreviation of 'sister'.

So, eusis could mean 'good sister'. But 'Rolf' doesn't sound feminine (unless he was a character in a prison), so anyway.....
