Well it was hinted that the previous Durandal wielder may try to steal Ex-Durandal, if that's the case perhaps Xenovia will gain a power-up so she isn't defenseless without it. While at the same time mastering its true power further.

Anyway, probably Koneko or Xenovia; the former is developing senjutsu skills extremely useful to the battles at hand, while the latter will be able to show off some amazing attacks when she masters Ex-Durandal.

Although if it's not limited to the ORC, I'd say Cao Cao :P
