"Your weakness is in your head, isn't it? That's why you're struggling so much," Iris declared with a menacing voice, applying her full strength to her grip, producing a cracking sound from the guardian's wooden head. Blood trickled from Iris's mouth as she spoke.
"Is that why you came straight at me? How did you figure that out?" The guardian responded with disbelief
"Do you think I'm that stupid? If your minion can die by destroying its head, then your head must also be the weakness!" Iris retorted. During the fight, she had observed the guardian avoiding and protecting its head more than any other part of its body—a clue that it was a crucial vulnerability.
Iris hadn't initially planned on resorting to this suicidal move, but after losing her arm, it became a desperate last-ditch effort—a gamble on whether her prediction was correct or not.
