After losing track of Oriana, T?ma and Tsuchikimado realizes Oriana is actually scouting the city to find the perfect location to use St. Peter's Cross. Thanks to the information provided by Orsola, they learn the Cross can only be activated in a large open area where the constellations can be seen at sundown. Tsuchikimado figures out the Academy City airport located at the 23rd district is the perfect area to activate the cross so he, T?ma and Stiyl heads there quickly as sundown is approaching. By the time they've arrived, Lidvia Lorenzetti, the Catholic nun that Oriana is working with, has brought St. Peter's Cross and starts activating it's magic while Oriana defends her from the trio, defeating both Tsuchikimado and Stiyl, with T?ma the only one left standing.
