(Well to be perfectly honest you already provided a 'Villain' and a reason to draw Zephyr back into his old combat armor as well. Since the Zinogre is a g-ranked monster it isn't something to be taken lightly. Even if the armor carries the memories of a harsher past that he at times regrets due to another reason he won't show blatant disrespect for the problem and won't forget what they're capable of. )
