Sakuya Maxima, her identity is....
...... so yeah, Xero's entire family has no normal people.
Speaking of which, the top three box containing the main characters still have one empty box, who think the last main character would be Rona, who carries the other Yukihime?
BTW, where did the Tears character got name change? I don't see it.
Blanche just use her first name, Ryuna just use her Kanji name, Rana is also an other name Elwin had used in the past....
