Quenser Barbotage

Quenser Barbotage (クウェンサー＝バーボタージュ) is a member of the Legitimacy Kingdom's 37th Mobile Maintenance Battalion and a trainee as a mechanic of Objects, aspiring to be an Object designer. Unlike many members of the military, he does not belong to an elite class. Quenser and Heivia were the very first people to destroy an Object without the use of another Object or nukes.

Etymology
is the name of medical procedure involving repeated injection and aspiration of a fluid. It is also the name of a cognac brandy and champagne cocktail.

Appearance
He is a blonde adolescent with a simple appearance. He wears a gray military uniform, has long silky blond hair and a feminine appearance, and is often described as "looking like a boy or a girl depending on what he wears".

Personality
Quenser is usually carefree and can also be somewhat perverted, as shown by his discussion with Heivia about Froleytia's breast size. He can be sly, serious and very smart when the situation warrants it. He is kind and hates leaving people to fend on their own, as shown when he went out to rescue Milinda on his own because no one else was willing to do that, because they knew that their enemy could be trying to use her to trap them.

Quenser has been described by himself as someone who has plenty of positive opinions, but is bad at seeing the risk when he thinks he has a way of winning, which makes Quenser thankful of Heivia's personality. This also might be the reason they work well as a team.

Quenser is a tech nerd/geek, and he's propense to getting excited at the chance of looking and/or examining any advanced technology or mechanism, especially those related to Objects.

Background
At some point in the past, a noble family who lived near Quenser went bankrupt and was left with nothing but debt and the grudges of others. Quenser's father gave them temporary shelter in his storehouse.

Quenser joined the army as part of his dream of becoming an Object Design Engineer, because of this, he sought the shortest military course and volunteers into the frontline deployment training, where he was assigned into the 37th Mobile Maintenance Battalion as a military engineer.

Short Story
Quenser and Heivia took part in a battle in Oceania, assisting the Baby Magnum against the Faith Organization's Aphrodite (codenamed Strategic Antenna). Though their initial strategy with the Floor Heater failed, they were able to figure out a way to destroy the Object and left a written message on it for the pilot.

The Circumstances Leading to a Certain Magical Heavy Zashiki Warashi’s Simple Killer Queen's Marriage
Quenser, Heivia and Milinda were some of the heroes summoned of Norse mythology for the crossover. The Baby Magnum was summoned with them.

While not of much help during the first fight with the black dragon, both Quenser and Hevia were active members of the group through the rest of the adventure, for example, helping fight the ice soldier during their quest. During the climatic fight with the shadows Quenser and Heivia saved Kamijou Touma from being killed by Hishigami Mai, and after receiving Tyr's blessing collaborated with Misaka Mikoto to defeat Mai. Like the other heroes they were overwhelmed by the arrival of Shirayama Kyousuke and his summoning of the White Queen.

In the end, the three characters returned to their original world thanks to Index's spell using the unique characteristics of all the heroes and their different worlds.

Skills and Abilities
Quenser is capable of analyzing information at his disposal, identifying key points and using them to come up with ideas on how to accomplish his objectives, an example being identifying an Object's weak points just by reading its instruction manual. He is also capable of making good use of what equipment he has at his disposal, as well as his surroundings and circumstances, in order to achieve his goals.

As a battlefield student Quenser is not a trained soldier, and while he has used firearms in some occasions, he's not particularly skilled with them. He's not even authorized to carry a military firearm since he's not gone through the appropriate training. Instead, Quenser has been assigned the role of combat engineer because of the training in handling explosives he received on his safe country school. After destroying his first Object, Quenser's usual issued explosives were changed from C4 to the more expensive and powerful Hand Axe.

Due to his studies and training to become an Object designer, Quenser is used as a mechanic for the Baby Magnum's maintenance, but since he's still on training, he can't handle any of the sensitive parts like the JPlevelMHD reactor or its targeting sensor control system.

Object designer Claire Whist has speculated that if Quenser were to become an Object designer himself and create an Object with his dangerous ideas, he could skip a few generations in the process.

He also knows how to play the guitar, something he apparently learned in an attempt to become more popular. He also learned to use a submersible on a field trip back in the safe country.

Trivia

 * Quenser and Heivia's act of being very first people to destroy an Object without the use of another Object or nukes, and continuing to do so, has earned them the epithet Dragon Killers (ドラゴンキラー) from the media, though this isn't mentioned very often.
