Believing her was hard, mostly because she was a Priestess of Purity, but Rex, in general, was lacking in terms of believing someone. Making sure that others' words are proper and backed with facts is the only way he could have peace of mind.
And in this case, Rex has no choice but to believe in Viora.
She knew already, so it was pointless to try and deny Kraken's real identity.
Still, having her hold all the cards is unsettling.
On top of Casey, it seemed he also needed to find out some dirt around Viora to secure his position.
"Besides…" Viora added, looking at him intently.
Rex frowned a little, "Besides?"
A small smile curled on Viora's lips, causing unease to rise within Rex.
"Besides, there are cute Voidal Monsters out there."
"… What?"
Rex thought his senses were still a mess, he thought he had heard wrong.
He blinked and then saw Viora turning to look at Kraken, who was still wrapped by the syal.
Both her eyes were glimmering with anticipation.
