絶頂成長！魔法少女ハルカ

Magical girls become strong by ecchi power! Haruka and Rino are chosen as magical girl. The two continue to fight against monsters to keep the peace by setting aside the dark organization called Abyss. On the other hand, Stark, one of the executives of Abyss, orders his subordinate Demon to summon a large number of monsters called Chaos from another dimension. He lets these monsters attack the magical girls to knock them down as a female, not knowing that the magical girls become strong by ecchi power...! Go, magical girls, go while getting sexual attacks!
