Shildina/Chronology

Volume 14
As Naofumi Iwatani's invasion of Q'ten Lo started to near completion Shildina was deployed to assassinate Raphtalia. Unfortunately for her superior's plot Shildina got lost on her way to the parade Raphtalia was to lead and ended up missing it, instead Naofumi, S'yne Lokk, and Erhard's Master ended up picking her up as they went out drinking.

Naofumi ended up playing cards with Shildina and impressing her immeasurably when he eats a Lucor fruit whole causing her to gain a crush on him. When they ended up having to part ways after Naofumi drunk the Master under the table she gives him one of her cards containing a piece of her soul that was removed as part of her oracle training.

Realizing that she couldn't track down the resistance nor could her forces defeat theirs in a straight-up fight Shildina instead sent a challenge to their forces: her vs Sadeena. At first, the resistance ignored preferring to continue to steamroll the enemy into submission, but then she puts on a show of force with cooperative class magic forcing their hand.

The battle between the sisters pushes Shildina to her limit as she continuously tries to prove that she has surpassed her sister, going to far as to use a card containing Sadeena's soul fragment from her time as a Miko and when that fails utilizes a cursed weapon and card containing a soul fragment of a past Seven Star Hero. Possessed by a malevolent force Shildina is forced to attack Naofumi's group who neutralizes the malevolent entity using Soul Eater weapons.

Once the malevolent entity is defeated the Hammer Hero fragment takes control of Shildina's body and uses her to wipe out the majority of the leaders of Q'ten Lo's corrupt government including Makina who is eliminated with the help of the holy heroes soul eater weapons. Afterwards, the Hammer Hero, a former empress of Q'ten Lo, challenges Raphtalia to a sparring match in which she thoroughly schools Raphtalia in the use of illusion magic and Raphtalia exorcises her ancestor from Shildina's body.

Shildina is taken to a hospital to recover and after a few days is visited by Naofumi, Ruftmilia, and Sadeena, who drags her off so that they can teach their parents a lesson.
