After he and Index arrive at Chioggia, T?ma tries to find Index after she gets lost but is found by Orsola who manages to find Index. Later, Orsola explains to them that she and the Amakusas are here at Chioggia to help move and pack her belongings to London. After helping them, T?ma and Index are about to go to their hotel when two assassins try to kill Orsola but their attempts are thwarted by T?ma and Index. One of the assassins escapes by summoning a Sailing ship made of Ice in the canal where T?ma and Orsola accidentally board it. As they hide from their pursuers inside the ship, both of them realize the assassins were from the Catholic church and there is a fleet of Ice ships heading towards the Adriatic Sea. When someone tries to enter the room in which they're hiding, T?ma prepares himself and is surprised to find out it's Agnese.
