The new girl is called Ingvild Leviathan, she like Vali a hybrid Maou discendent/Longinus possesor. Her longinus is Nereid Kyre( she can controll the sea, and take the controll of dragons, her power is so great that througth her chant is dangerous comparable to Samael, when she chant the Nereid Kyrie generated lavanda particle). She was targed by Hades(because she can summon tsunami, and perphaps have the potential to controll even Ophis and GR.) Issei and the others save her from Nxy, with Issei that summon Ddraig, Issei said to Ingvild to chant for increase his power, Issei use Akeno boobs for the Paiphone, the DXD working effect is like trasfer and the lavanda particle give a boost to all girls.
