Over the years, Chicago Fire has showcased some of the strongest female characters in network television, and right now, no one is making more waves than Stella Kidd (played by Miranda Rae Mayo) and Violet Mikami (played by Hanako Greensmith).

Stella, once a fresh face among the veterans, has grown into a powerful leader. She’s not just Severide’s wife—she’s a firefighter who stands her ground, leads Squad 3 with courage, and fights for what’s right. Her Season 13 arc proved just how far she’s come, with fans still talking about her promotion struggles, her emotional strength during Boden’s absence, and now, her unexpected pregnancy reveal.

Meanwhile, Violet Mikami is carving out her own space as one of the most beloved paramedics the show has seen in years. Her journey from heartbroken after Hawkins’ death to rediscovering her spark has made her a fan favorite. Hanako Greensmith has brought vulnerability and resilience to Violet, and fans on social media can’t get enough of her friendship with Brett, her no-nonsense attitude, and her emotional moments.

In a show filled with big action scenes and dramatic fire rescues, it’s the grounded, emotional storytelling around characters like Kidd and Mikami that keeps viewers hooked. They’re not just part of Firehouse 51—they are Firehouse 51.
