Tsubomi Kido/Relationships

Kano
Kano and Kido grew up in the same orphanage together. He tends to tease Kido a lot and gets hit or kicked by her for it most of the time, since she doesn't show any tolerance for it. Even though he gets called an "idiot" or "bastard" by Kido a lot, they seem to be very close childhood friends. Kano describes Kido's past self as "cute".

Seto
Seto and Kido grew up in the same orphanage and are childhood friends.

Mary
Kido met Mary the first time as Seto took her with him to her house. Mary soon became a member of the Mekakushi Dan after that. Nowadays Mary is seen often clinging to Kido, wanting to be protected by her from the people outside.

Momo
Kido met Momo when she walked across her crying in an alleyway by herself. Kido led her to the secret hideout and let Kano introduce Momo to the Mekakushi Dan. She became a member of the gang after that.

Takane
Kido went with Kano to Takane's culture festival in the novel, "A Headphone Actor". Both Kido and Kano decided to play in Takane's booth. Back then, Kido couldn't control her power yet, so Takane couldn't really see her after introducing the game.

Ayano
Ayano was told by her mother to be a "big sister" for Kido, Kano, and Seto. She was the one taking care of them in the orphanage. Ayano followed her wish and started to become friends with the three of them, what turned out to be difficult, as they thought of themselves as "monsters", due to their eye abilities. Eventually, Ayano came up with the plan to create a secret club of heroes and gave them their hoodies as a present
