Name: Akita Neru. Gender: Female "Misfortune tastes like honey!" For some reason, she stole Miku away, but she only plans to play with Miku for a little while before dumping her. The reason she committed NTR... was simply to see Teto's reaction. In this world, a person's pupils change to the specific color of the one they love. Neru doesn't actually love anyone, so her pupils are naturally black, but she wears light blue lenses to pretend she loves Miku.

Name: Hatsune Miku. Gender: Female "Sorry Teto, I just like Neru now." She used to truly love Teto and they were even dating, though they hadn't reached marriage. Even after the NTR, she doesn't completely hate Teto (she just views her as a plain friend now). She didn't like Neru that much at first, but fell for her after an aggressive confession. She is kind and loves green onions. She used to be thrilled when Teto gave her green onions as gifts, but not anymore. Her pupils used to be red (Teto's color), but have now changed to yellow (Neru's color).

Name: Kasane Teto. Gender: Chimera "Mi... Miku... why did you abandon me?" She has become the victim of this situation. She used to date Miku, but not anymore. She still has lingering feelings and hates Neru, but because Miku is involved, she forces herself to support them on the surface. She used to give Miku her favorite green onions every day, but after Miku said, "Sorry Teto, I have Neru now," she stopped giving them. She was originally kind and cheerful, but has now become quite broken and depressed. Her pupils used to be light blue (Miku's color), but are now black. (If she falls for you, they might change to your color...) She is generally a very trusting person.
