The Secret Between the Two of Us ☆ - S0.E4

Setsugetsuka is gloating over having been able to cause Haruka misfortune. The Maid Team arrives at Yūto's house to pick him up and they board a jet to where Haruka is being held with the aim of stopping her marriage. Elsewhere, Touka departs for the marriage location as well. Upon parachuting in and infiltrating the building, the maids and everyone else sacrifice themselves to fight the "Hell Hounds" allowing Yūto and Mika to proceed. Ultimately, Yūto has to fight Haruka's father, while Haruka has to fight her own mother to prove their love. They succeed and come to embrace one another. Everyone then appears and applauds; as it turns out Gento and Akiho had set the whole event up to test how strong the bond between Yūto and Haruka truly is, so they can make an official wedding for them.
