Whilst Heaven Canceler attends to Seiri, Stiyl manages to lead T?ma and Tsuchimikado to Oriana's location. Oriana inflicts a curse on Tsuchimikado and gives T?ma trouble with her variety of spells, yet T?ma's determination allows him to land a hit on her. Oriana escapes but leaves behind her cargo, which is later revealed to be a decoy. Laura soon learns that the Stab Sword is actually St. Peter's Cross, which she fears the Catholic Church will use to put Academy City under their control if the trade goes through. After T?ma, Stiyl and Tsuchimikado are informed of this, T?ma has lunch with Index, his parents, Mikoto and Misuzu, and is surprise to learn Misuzu is Mikoto's mother.
