Sierra's eyes widened as she saw Stark narrowly avoiding her arrows that were being scattered in all possible directions in the tunnel, hoping for just one of them to hit his shoulders or any part of his body at all.
She clenched her fists and whispered, "Not today, human…"
~FWISH, FWISH~
'I just need one…'
~FWISH~
'Just one arrow is enough to end this…'
~FWISH~
'PLEASE!'
Much like Judicator, Sierra was a 'Godless Demon' apostle, but also a boss, meaning that she wasn't supposed to be scared, instead supposed to be boasting of confidence and power, this was why she showed herself early in the rift to challenge all humans and kill them.
But she had been forced to run away from Stark as deep inside of her mind, his aura at that time was truly overwhelming, and her face still hurts a bit from the punch he had sent.
