"Centaurs & Harpies' Retreat" 

After finding this world with real cute cats who didn't look like aliens, Cerberus immediately loved this world and all the cats in the Beast Continent. 

There, he found Bello, and guided him to be the shadow guardian of the Underworld because he was the most suitable. 

When Hydra said that he would bring some kittens and cats to Cerberus, he was just joking because he knew that Cerberus already had Bello. 

And for Cerberus, Bello wasn't a pet. He was a family. Maybe a son? A brother? Who knows. 

Although Cerberus would love to keep a few more genuine kittens and cats in the underworld, those weak creatures couldn't survive. 

Cerberus shook his three heads in disgust and flicked his tail sharply, urging Hydra to enter fate and shut up. 

"Just spend more energy and money in the Underworld, little brat. If not for you being one of the VVIPs there, I won't even bother to help you."
