Rosario Vampire, Volume 4 (Rosario Vampire Vol. 2 #13-17)

Kahlua Shuzen arrives to enforce alliance negotiations between Fairy Tale and the Snow Fairy world, but as things do not go as intended, she goes into her crying tantrum and beats down everyone, including the News Club girls. She fights Moka but sustains heavy damage; Miyabi arrives and cancels her "kill everyone" orders and they retreat. Ruby takes Tsukune to another dimension where Tsukune trains in controlling his ghoul power, fighting with a special magic-cancelling whip while Ruby uses a chain to absorb his excess power. Moka steals the whip and, as her inner personality, goes on a date with Tsukune where the latter learns how to sense monsters.

Tsukune and Moka have more sparring sessions. Koko helps Kurumu try to win Tsukune's affections by egging her to use her charm ability. Kurumu charms some boys, but Tsukune is inadvertently affected and Kurumu and Tsukune find themselves alone in Kurumu's dorm room.
