Choujuushin Gravion Zwei EP5 - The Dream Solitary Isle

The gravion gang goes to an amusement park Grand Island with some of the maids. There's a Zerivire there. Back at the base, the maids protest to Raven that they want to go to the park too. Back at the park, they can't find anything wrong initially. Leele laments that she doesn't have any memory of her past; the others tell her that she can simply make some by being with them. Leele and Toga are in a skyride by themselves, and Leele makes a move on Toga.
