Zena Marienteil

Background
Zena Marientail is a magic soldier belonging to Seryuu city's territorial army, her lineage is of the Chevalier Marientail house where her family are retainers of Earl Seryuu. She has a younger brother who is currently the family head. Though her family are nobles, they are of the lowest rank, with humble riches and lacking status in governmental politics. Zena's an adept wind user and evaluated to have a promising future as a soldier.

Appearance
Zena has a slender body and long straight bob hair, though teased for her flat-chest, she's considered a 'charmingly beautiful girl' and/or 'plainly cute'.

Seryuu City
Whilst trying to complete her duty as a magic soldier of the earldom, when the Seryuu Demon attacks Earl Seryuu's castle; Zena is attacked and thrust away crashing into a tree. Satou rescues and takes her to a medical station when he finds her dangling in her a tree. Her encounter would further cement her wish to fly, as she marvels at Satou who carries her injured body and at same time jumps from building to building with both haste and caution so not further injure her. She jokingly later refers to him as Mr. Nimble because of his athleticism. They further become acquainted when she spots him in a front a bookstore and a spontaneous date is born from their time spent together. She's bids her farewell to Satou when he leaves the city for Labyrinth city and they promise to write letters to each other.

Journey to Labyrinth City
After Satou leaves Seryuu city for Labyrinth city, and approximately half month has passed, Zena is chosen as a member of the labyrinth city Selbira training selected corps--a force created by Earl Seryuu as a means to gain necessary knowledge in care-taking and commercializing Seryuu city's new labyrinth by studying the veteran Labyrinth city. This is all due to the collective agreement of Zena and her close friends Lilio, Ruu and Iona, who all had their own personal reasons for the joining the corps but wanted to help Zena achieve her love by going to the labyrinth city. Incidentally, within the corps Zena is the leader of a magic squad consisting of her and her aforementioned three friends.

Lesseu Earldom
The march of the corps had been relatively smooth with only insect-type monsters and minor thieves attempting to obstruct their journey until they enter the Lesseu Earldom then meeting the territory's defeated army and discover that Lesseu city has been destroyed by a mid-class, level 40, demon that also brought along 1400 rampaging monsters.to the territory. Further hearing that the monsters are stronger than average soldiers and the demon alone annihilated Lesseu city's army, Zena becomes anxious on whether her low-leveled corps (with three magic soldiers including her) can defeat the higher-leveled demon and monsters let alone repulse them. Surprised by the young lord, Earl Lesseu, who wills the cooperation of the labyrinth selected corps under the pretext of [Blue Covenant]; the oldest covenant that has been passed over among the nobles since the founding of Shiga kingdom. A covenant that indiscriminately decrees all forms of military in Shiga kingdom has to cooperate together in case of demon attacks. The labyrinth selected corps--thus Zena's squad--become part of an impromptu army at the second city of Earl Lesseu's territory. The whole force consisted of 800 regular soldiers, and 2000 militia. Even though twice the monster's number, the militia are padded forces. But Zena hypothesizes that if the demon attacks directly and they use the city's wall insisting on a siege war there are more chances of winning. But Zena despairs thinking she won't be able to keep her promise of sending letters to Satou when the young Earl Lesseu decides to fight the monsters and the demon on an open field despite the captains' pleas.

During the battle on the field, a black dust covered Zena and her squad are recovering from a daze caused by an advanced level tactical magic fired by the demon. Zena realizes that they are pinned by the approaching monsters waiting to take advantage and the demon in sky waiting to fire its magic without mercy. At that time, the sky is divided and Saga Empire's hero, Hayato Masaki, on his silver ship, Dimensional Traveler Jules Verne appears. With one of swing of his holy sword, Arondight, the mid-class demon is destroyed and the many monsters are destroyed by the ship's beam. Zena is awed by the overwhelming power of the hero, considering his intrusion in the battle to be a miracle. She then resolves herself that she wants to become stronger so that next time she will stand the one who creates such miracles.

After the battle with the exit of the hero, Zena and her squad, are searching for survivors. During so, Earl Lesseu, personally seeks out Zena, on the pretense of complimenting her good works during the battle. Aware that she's of the Chevalier Marientail house, he offers her the position of his retainer with honorary noble peerage with the promise of making it permanent depending on her work. Zena refuses the invitation because her family has served Earl Seryuu for generations and she has no intention working for another house. Not expecting such an answer the earl becomes slightly angered but reigns himself in, to the extent, he's able to promise a vacated seat as retainer for her if she changes her mind. Norina, a similar magic soldier to Zena in the labyrinth selected corps, informs her of the subtext of Earl Lesseu offering her a position; Norina was also offered such a position but not by the earl but by one of his retainers, which means there's was also a possibility of the earl attempting to court Zena as a future mistress and seeking her as a magic soldier for his own troops might have also been a pretext.

After ten days elapsing after the fight with the demon and heavy losses, a limbless Baron Derio, the captain of the Labyrinth Selection Regimen had returned early to Seryuu territory to brief the earl about the situation. Vice-captain Rilo who had also lost a limb informs the corps--via a carrier pigeon with a message from Earl Seryuu--that they are to continue onward towards Labyrinth city but those who have lost their will or have lost limbs are to return to Seryuu city. This includes Rilo who makes Knight Henz the new captain of the corps of a now 18 people (which was once 24 including 300-plus people under their protection) with two magic squads (including Zena's), Knight Henz attendants, civil officers and two squad-less soldiers going to Labyrinth City, Selbira.

Zettsu Earldom
Zena and the remaining corps entered Zettsu Earldom after defeating remnant monsters collected by the mid-class demon that had built nests on their way and at the borders of Lesseu and Zettsu. Zena haggard by the constant battles after the long journey from the north to the south of Zettsu Earldom, finally reach its southernmost city. Which feels her with hope because once they leave this city they will be entering the territory directly under the royal family and then its Labyrinth city where Satou awaits. Plans to move onward from the border city, Fau, are halted as Zena and the corps later find out that a lower-class dragon has nested in the mountain range on the territory's border preventing all caravans and journeymen from going to the royal capital which also includes the on-the-way Labyrinth city. A month passes without any progress or countermeasures against the dragon and they stay stuck in Fau city; their only choice would be to detour the mountain-pass the dragon occupies by going back to Lesseu Earldom, then go through the mountain range in the south route passing through Muno Earldom (of Shiga kingdom) or circumvent through several small kingdoms by passing through Eluett March (of Shiga kingdom). These options are not profitable as it would have extended their journey by several months or cast needless suspicion on them, if they as foreign soldiers, maneuvered in other countries.

Zena is informed by Lilio and Ruu who went to investigate for a shortcut, ten days ago, that though the shortcut is passable for the soldiers it would be extremely laborious for their accompanying civil officials and maids. They also inform her that the lesser dragon is 'probably a sub-species dragon-monster like wyvern or hydra' because of its ominous and eccentric characteristics of spewing out mist that can melt rocks, its fondness for oranges and that it's actually larger than a lesser dragon. Zena, Lilio, Ruu then reunite with a young black-haired one-armed man, they were acquainted with in Seryuu city, who Zena had mistaken for Satou. The young man via Lilio tells Zena of a new shortcut that's even unknown to Fau city; where there's a road that goes pass the valley where the dragon resides but carriages can't pass through there, but there is a gentle slope for walking better than the the other shortcut.

After reporting to the captain, Henz, Zena's squad is instructed to scout out the shortcut with the possibility of meeting the dragon. With no hope of the Royal Army coming anytime soon to repulse the dragon and the exceeding prices of Fau city that made it had to secure provisions, Zena reluctantly resolves herself to carry out the scouting mission. In order to ascertain further information, Zena's squad again meet up with the one-armed man who Zena frankly calls 'Lilio's boyfriend' because of the girl's romantic interest in the man. He informs them that the valley also has harpy nests and there are surrounding rocky areas that spring out slimes. During this conversation it is revealed that the man is named 'Jon' (or rather how Zena hears the pronunciation) by his female acquaintance, Mito, who calls out to him. Zena's squad then heads to the aforementioned Withered Valley, due to spraying steam from the ground, the trees there have withered. With the poor visibility because of the steam as they move through the valley, they are taken by surprise by an attack from a harpy. But with practiced commands given by Zena, her squad take anti-air formations whilst she cast a sound protection spell against the sleep-inducing harpy leaving it to Lilio's crossbow to winged it and Iona to mercilessly smash its head with her great sword. Zena affirms the suspicious movements of the harpy when she realizes it was being chased by a dragon.
