Nijimi Anazawa[]
Mikado was Nijimi's best friend. When Nijimi first became a Magical Girl, Mikado helped her and taught her how to use her stick. It was stated by Nijimi that Mikadon was the magical girl who had been her one and true friend. Mikadon's death was the reason of Nijimi's desire to kill Rina Shioi for the death of her best friend.
In Nijimi's final moments, she apologized to Mikado for having such a bad temper.
Rina Shioi[]
The interactions between Her and Rina are Limited, Since they both didnt have much dialogue conversations with eachother. Rina Shioi is the one who killed Mikado Ikemata, which caused Nijimi to hold a grudge against Rina. Mikado was unaware of who killed her, so she died not knowing that. Rina and many others have used Mikado's stick many times.
