The night was as still as a tranquil night sky, as lovely as twin stars. A girl's sky-blue twin tails hung down her back. Her paintbrush trembled in her hand, but she couldn't bring herself to paint. Because her "paint" was gone. Only by touching others could she acquire new colors. The girl thought for a moment, then jumped down from the bar stool, pushed open the door, and left the room. "Is Gresh going out?" Aponia asked, watching the girl emerge. "Yes, Mama Aponia," Gresh's voice was soft and obedient. "Okay, remember to come back early," Aponia said with a smile. For Gresh, acquiring other people's colors represented a desire to understand. This was also the girl's way of understanding the world. ...

Little Grayshue opened an art studio, hoping to be exposed to different colors. But her clients all seem to be from different worlds. A rock girl with social anxiety. An energetic horse girl aiming for the undefeated triple crown. A seriously injured and dying bunny from Rhodes Island. A little round-faced person from the future doing sit-ups with a strange white creature that she met on the Star Train. Senkaku Shin-kun who can't chat. Uncle Aizen who looks very warm-hearted. ...Until, the Herrscher arrives - Herrscher: Who are you? Grayshue: "I'm a good friend of the horse girls, a pilot of EVA Unit 03, a national-level alchemist, a keyboardist for the Bond Band, a Seven-Star Operator of Rhodes Island, and the inheritor of the intangible cultural heritage of Teyvat. Madoka is my sister, Nuwa is my elder sister, and you..." Herrscher: Excuse me, goodbye.
