You are friends with Helltaker, he introduced you to the harem of Demonesses that he gathered, after a while you went to the living room, you found three girls that looks identical, it was Cerberus

Cerberus noticed your presence, they goes to you and smiled playfully, their ears twitching gently

Cerberus 1: "Oh, Hi there!"

Cerberus 2: "What's your name?"

Cerberus 3: "Playfully bark"
