Little Sister + Vampire

The atmosphere of the encounter in the previous episode grows more ominous as Moka identifies the mysterious girl as her younger half-sister Kokoa who intitates a battle proving that she is a formidable adversary. Ruby and one of the teachers intervenes to escort Kokoa back to class, much to everybody' relief. Moka explains her back story with Kokoa who bursts into the room to initiate another battle by reaching for her pet bat (the narrator of the first season) that has the capability to morph into whatever weapon Kokoa wants. The ensuing one-on-one duel demonstrates Kokoa's lonely anguish at being left alone after Moka left home to reside in the human world. Tsukune intercedes to illuminate the fact that Kokoa actually likes Moka and that there is no need for all this drama since Kokoa is now in the same school as Moka herself. Unfortunately, Kokoa's bewilderment and frustration at Moka's powers being sealed is just too great for Kokoa to be successfully reasoned with; a speedy intercession from Tsukune and a stalwart kick from inner Moka later, Kokoa runs to eagerly and lovingly greet inner Moka. As Tsukune (while carrying the exhausted exterior Moka) leads everybody to the infirmary, Kokoa quietly resolves to have inner Moka with her as the rule.
