The concubine cuddles up against Kina. "Yes it was, lover." She grins. "You'd better head out, though, before you're late for your tests." Kina realises that, having both the time of the shinobi's meeting, and the name of the concubine's enemies, she can simply write a note and set Inobi up right now. Once that's done, she has a choice. Since she's only an applicant, she can leave the palace freely, though she won't be allowed back in if she does leave before her trials are over. Alternatively, she could stay to see the results, and then leave. Or, she could complete her trials, which she's confident that she can pass, and become an official concubine.
As she ponders, Kina has a strange feeling. It's almost like a bond being cut, seperating her from her Yokuboo masters. Unbeknownst to her, the curse placed upon the Rai Clan is broken. Her devotion to the Yokuboo remains, having been thoroughly mentally broken by Jurobei, but the supernatural curse preventing her from physically harming a Yokuboo or bearing a male child has lifted. Kina doesn't understand what happened, though, only the strange feeling of freedom that the sex slave finds deeply uncomfortable.
