A Certain Magical Index II Episode 12 English Dubbed Episode Title:The Observatory (Belvedere).Episode Description:After losing track of Oriana, it is then that Tōma and Tsuchikimado realize Oriana is actually scouting the city to find the perfect location to use the Croce di Pietro. Thanks to the information provided by Orsola, they learn the Croce di Pietro can only be activated in a large open area where the constellations can be seen at sundown. Tsuchikimado figures out that the Academy City airport located at School District 23 is the perfect area to activate the cross, so he, Tōma and Stiyl head there quickly as sundown is approaching. By the time they have arrived, Lidvia Lorenzetti, the Catholic nun that Oriana is working with, has brought the Croce di Pietro and starts activating its magic while Oriana defends her from the trio, defeating both Tsuchikimado and Stiyl, with Tōma the only one left standing.
