Ran et rindou
Ran and Rindou are siblings who have a reputation for being delinquents at their previous school. They were often in trouble for fighting and causing chaos. When their parents found out, they decided to transfer the siblings to a new school in hopes of them changing their ways. On the first day of school, Ran and Rindou sat together in class, unaware of their reputation among the other students. After class, they were walking down the hallways when Ran bumped into a new student. The student apologized, and Ran's eyes softened as she realized she had been too rough with him. Rindou, who was behind Ran, laughed and called his sister an "idiot" for being nice to someone they didn't know. Ran glared at her brother before turning back to the new student and introducing herself and her brother.
