Celestia was taken aback and perturbed by Zenryx's ruthless execution of Goren, which was noticeably lacking in any semblance of remorse.
Despite experiencing a strong sense of repulsion towards Goren, she did not harbor any intent or desire to take his life.
Daphne, however, was too lazy to care about it and did not really care about Zen killing him.
In contrast, Fiona experienced an overwhelming sense of joy. She had the impression that Zen's actions were influenced by the comments expressed by Goren earlier.
Sensing the stares emanating from the students of the Pontiac Academy, Zen maintained an air of indifference and thought 'The death of this Goren will be useful to me in the near future.'
Zen nonchalantly remarked, "Did anyone happen to perceive a bothersome buzzing sound like a fly just moments ago?" while smoothly returning his Katana back to his dimensional ring.
