Arita orph Reiko is a bully who held the rank of 10. As observed in Chapter 227, she had the command over an army of grade schoolers named the "Arita Army," along with a "castle." She planned to rule the school. But later on, when angered by Tenri (when it was actually Keima who had angered who), she attacked her, but was defeated by "Tenri" (in truth, Elsie used her Hagoromo to attack Arita before Arita could lay a finger on Tenri).
By the next chapter, she announced her retirement and left to train herself, as a person and as a woman.
