An interesting thing is that Alisa,
her descendent Eusis...
...and of course her
clone, Mina
all of them wear an headband (probably an heritage taste)
So... imagine Alec follows Arisa orders and actually marries Mina... how would their descents be? (I was talking about taking care... not only sex).
How about the fusion of the two sprites for an answer?
Shir (the thief from PSII) is also similar to Mina and another thing is that Chaz (when he was younger) was also a street thief.
[Just a thought but a possible family tree could be Arisa~.~.~.>Alec+Mina->x->x->Shir->x->x->Chaz]

I just have another thing to say. "Kaburon" means something nasty in my mother language.
