We will take down Gensou City's management system, the Omoikane Device.
Omoikane is the Shinto god of wisdom and intelligence, whom Eirin is based on.They maintain DEVICE. Their greatest motive is to remove the possibility of "eternity" being destroyed. So, Of course, they would not allow any manipulation of history related to that.We want to change history to take out a girl who is imprisoned in that cage of eternity. That’s why we have to either convince or defeat them.Tonight we will attack Eientou (Eternal Tower)I will help, but… can we know about the situation ?
