The Warlord's Revenge

Vonruil says, smiling, "Ah, since when did he become invincible?" 


Keona looks around and says, "Damn, where'd he go? Now what do I do?" 


Remembering she has to get his blood if she wants to get the underworld spirits, she changes her tactic and jumps to hug Vonruil and says, "Vonruil, he has my friends. I was forced to do this. Please save them." 


Vonruil pushes her away and says, "Like for real? You, the princess of Eucarro and Goddess of Spirits, are asking me to save her friends. Where are your people, or are they so useless they can't even save their own beings? If so, then who's protecting you and your father?" 


Keona tries to smile as sweetly as she can and says, "Of course you are there to protect me." 


Vonruil says in a stern tone, "And why would I protect you? And don't say, 'You're the warlord or the custodian, because, as the custodian or the warlord, I have no obligation to go around saving every single living being in the universe."
