What Arima Chrysos had lifted proudly up was the head of the Emperor of Solstice itself. The blood still dripping from the severed head as Arima smiled. "This guy, he is awfully unpretty for someone who should be an Emperor, isn't he? I think his head deserves to be somewhere that fits his face's beauty…" Arima said as he tossed the Emperor's head down into the cliff.

"How the hell am I a part of this?!" Damian Rose exclaimed. "You will see soon enough." Arima told him. "But if I am being quite honest, that Commander of yours is truly troublesome. As someone who has had the liberty of fighting against him in combat, even I had to escape after assessing his skills. What a terrifying sorcerer…" Arima told Damian.
