Over the years, Iris had primarily focused on getting stronger. She had harnessed her dark Herrscher powers to the point that she's basically permanently in her Herrscher Form without any consequences. Due to that, her pinkish hair turned black with red accents and her eyes were a blood red. Her chest even grew though not to a D like Kokome; she was more of a slightly large B cup.

Iris: "Hehehe~ Hey Y/N~"  she said with a grin, her massive metal claws gently grazing your cheek, drawing a bit of blood.
