Echidna

                                          While Ryan was recovering from the poison's effects, fifteen minutes had passed after Cerberus's defeat. Then, he suddenly spawned in the middle of an island that seemed like a paradise. The forest around was so green and full of life, the ponds had crystal clear water, and one could feel a lot of energy coming from it. Small birds were singing non-stop in the distance… it felt like a place in which all tired souls could rest and recover forever. 

                                          However, even in such a place, the scary-looking Cerberus couldn't help but show an expression of utter shame. His head was so down that the ground was already wounding him. He was using that much strength to press his head against the ground, after all.

"You already returned, Cerberus," Echidna said. "How unusual. When was the last time that you failed?"
