The Unaligned (male child reader X adoptive mother Shizuku Sango)

Kampfer are girls who are given the power to fight by the moderators. They are split into two factions, the red and the blue.
One day after finding a strange stuffed animal (y/n)'s life changed for the worst when a strange bracelet appeared on his arm, a bracelet that was neither red nor blue but transparent.
She was a part of the red faction and yet she felt sorry for this young child and took him in.
