Rank 1 Witch Haruriri Descends Episode 8

A cute girl with an umbrella and a twin tail descends from above Kota while attending school. I came. Calling her first-class witch, Warla Haruriri, she tells Kota that she "has come down to sign a contract with you." Haruriri tells Kota, who runs away if she is dying to take her life, "no special compensation is required." She came into contact with her when she knew that she was a classmate from the magic school of Rumono and was a contractor of Kota. If you make a double contract with a witch, the new contract will take precedence. Chiro, who thought that Haruriri had come to harass her, hangs on her, but Hitoru keeps her expression saying, "It's up to Kota." What is the real purpose of coming to this world of Haruriri?
