In the aftermath of the battle between Isumi and Yozora, Hayate is cleaning the Mystery Room. He notices that there are symbols on the floor where the coffin used to be and realised they also appeared on his King's Jewel. He infers that there are 12 King's Jewels since there are 12 crests in total. Isumi comes in and summarises that the coffin used to hold a great power and that there were those who were protecting it. But the power was loss one day and the mansion was handed over to Yukariko due to it having loss its value. She later states that whatever that power was, it cannot fall into the wrong hands. Hayate is later seen grocery shopping with Chiharu for a Welcome Party suggested by her for the new tenants to get to know each other. Back at the Violet Mansion, Ayumu notices that Ruka seems troubled and concludes that if she can solve her problem, she wouldn't have to rely on Hayate and thus won't have feelings for him. However when asked, Ruka states that the problem was "would Hayate become her boyfriend if she confessed her feelings for him" thus leaving Ayumu speechless.
