Eckhart/Story

Eckhart first encounters Myne directly during the trombe extermination mission with the Knight’s Order, although they do not meet directly. Eckhart participates as a knight, while Myne is assigned as an apprentice blue shrine maiden to perform the Healing Ritual following the feyplant's eradication.

Due to the incompetence of Shikikoza, Myne is attacked by a second trombe and has her mana drained. However, she escapes safely due to Ferdinand’s intervention and impresses the knights by easily completing the healing ritual. Eckhart, along with the others, is struck by her remarkable mana capacity, which is on par with most archnobles her age.

Eckhart is first introduced to Rozemyne as his younger sister just before her baptism, when he is 18 years old. He picks her up and is surprised to remember her as the same shrine maiden who healed the land after the trombe extermination. .

When Rozemyne goes to gather ruelle fruit during the Harvest Festival, Ferdinand assigns Eckhart and Justus to accompany her in addition to her usual guard knights.

Predicting that Rozemyne will be invited to receptions involving alcohol and women, based on expectations set by the the previous High Bishop, Ferdinand preemptively instructs her to refuse all invitations and tells Eckhart to accept them in her stead.

While they are in Hasse, Rozemyne learns from Eckhart that, while she had decided not to make Ferdinand her enemy out of fear, he and Justus resolved to serve him out of sincere respect. He tells Rozemyne not to lump herself together with them.

Later, Eckhart becomes suspicious of Richt, who is acting nervous, and escorts Rozemyne back to the monastery as a precaution.

On the Night of Schutzaria, the last full moon of autumn, Eckhart is present with Rozemyne’s party in Dorvan. He, Damuel and Justus go out to look for a ruelle tree during the day and mark it for the return mission at night. He attends Rozemyne as a guard when she goes to collect the ruelle, and battles the horde of feybeasts that gather around the tree.

When a zantze eats the ruelle dyed with Rozemyne’s mana and evolves into a goltze, Eckhart leads the battle against it.

It is later revealed that Eckhart had been sent to investigate Myne in the lower city alongside Justus shortly before she entered the temple and long before she was baptized as his sister. However, Eckhart is quickly overwhelmed by the unpleasant smell and unsanitary surroundings. While he rests to recover from his nausea, Justus disguises himself to question commoners around the south gate.

After the investigation is unsuccessful, Eckhart and Justus break into the Merchant's Guild to investigate her official records. They eventually gather enough information, and Eckhart reports to Ferdinand while Justus visits the Lower City market.

When Ferdinand returns to noble society, Eckhart is overjoyed and serves him as a guard knight once again. Although it is not technically required of a guard knight, Eckhart also helps Ferdinand with his paperwork at the temple.

Because Bonifatius views Angelica as a prized disciple, he insists that she marry into his family. Because Lamprecht was already in a relationship, Cornelius had feelings for someone else, and Traugott was disgraced after being dismissed as a retainer by Rozemyne, Eckhart was the only viable candidate for her fiance.

Angelica’s parents tried to prevent the engagement, concerned that their daughter was not suited to be the wife of an archnoble. Eventually, the families agreed that she would be engaged as Eckhart’s second wife, and therefore would not be expected to appear in public as a representative of the family.

Both Angelica and Eckhart are inclined to postpone the marriage as long as possible, and both are happy to use the engagement as an excuse to avoid social obligations. Angelica agrees to the engagement mainly due to her blind trust in Bonifatius. Meanwhile, Eckhart remarks that a girl uninterested in love and romance is a perfect match for him. He visits the Royal Academy to serve as Angelica’s escort during her graduation.

Spoiler from Part 4 Volume 5

When Ferdinand devised the magic circles to be used in the creation of Schwartz and Weiss's new outfits, Eckhart assisted him in testing out the improved magic circles by directly attacking objects with the circles inscribed on them. All attacks were consistently reflected into the attacker, showing them to work as intended. However the pair only used light attacks for safety reasons.
