Willem Kmetsch

Willem Kmetsch (ヴィレム・クメシュ, Viremu Kumeshu) is a 2nd Grade Technical Officer who works for the Guardian Wings Military. He is the main male protagonist of the Suka Suka series and a supporting character in the Suka Moka series.

Background
Willem is a soldier who works for the Guardian Wings Corps as the Caretaker for the Fairy Warehouse. Willem is the last human, or Emnetwiht, known to be alive after the fall of the surface. The petrification curses that he suffered from were lifted 2 years before the events in the LN/anime took place.

Past
500 years ago, Willem was born into the human race which later came to be known as 'Emnetwihts.' For an unknown reason, he came to be raised by an orphanage which was founded by his legal caretaker, Nils Didek Foreigner.

As Willem grew up, Willem eventually took over as the main caretaker of the facility and came to be called "Pops" by the rest of the kids, including Almaria Duffner as he was viewed as the unofficial father figure for the rest of the kids.

Becoming a Quasi Brave
Growing up, Willem's dream was to become a Regal Brave warrior. During his training, Willem met and trained alongside Lillia Asplay and Souwong Kandel under the same master and mastered many skills. However, because Lillia didn't want him to become a Regal Brave out of concern for his safety, and also due to Willem’s lack of battle talent, he was only able to become a Quasi Brave.

As a former Quasi Brave, one of a group of elite warriors that served the Church of Holy Light along with the Regal Brave, Willem was known as the strongest of the Quasi Braves. Even though this is later revealed to be a joke made by his comrades, it is heavily implied that he was in fact the strongest of the Quasi Braves. He was also given the title Black Agate Swordsmaster due to his talent in tuning Carillons.

Becoming Petrified
During the final battle against the Visitors, Willem fought Ebon Candle and was eventually able to beat him by himself. However due to the backlash effect of the curses that he used. Willem was petrified for approximately 526 years ago. This petrification process occurred before the seventeen beasts appeared and less than a year before humanity went extinct.

Appearance
Willem Kmetsch is a physically 18 (544) year old male. He is roughly 6 to 7 feet tall and has black hair and brown eyes.

At work, he normally wears either his Guardian Wings Military Uniform which consists of a black jacket, a grey shirt, black pants and knee-high black boots.

Due to his past war experiences, Willem's body is riddled with scars, broken bones and damaged organs which he calls his "Battle Scars. " As such he is unable to use the full extent of his abilities and can only use spells and Venenum abilities for an extremely limited amount of time.

Personality
Willem is a kind person who likes to joke around with his friends. Having grown up in an orphanage, Willem enjoys playing with kids and likes to play games with the children. However, thanks to Ithea, it is often misinterpreted as "being into little girls".

Willem also cares about people and is thus tolerant and patient towards others, even those who despise him for being an 'Emnetwhit' or a 'Disfeatured’. Due to his experiences in war, Willem hates war and the reasons behind them, and as such, is sympathetic towards the Leprechauns' plight and is willing to do whatever it takes to prolong their lives.

Initially, at the start of series, Willem was a much more jaded person. Due to being the only survivor of his race and struggling to find his place in this new world, Willem was plagued by guilt by what happened and sought to merely wait out for his death, rather than trying to find happiness.

However, after encountering Chtholly and becoming the caretaker for the Leprechaun Warehouse, Willem regains his joy, peace and love for life, even to the point that he falls in love with Chtholly and is willing to sacrifice his life to save the Fairy Warehouse.

Weapons
During his time as a Quasi Brave, Willem used a multitude of weapons. His weapons extended from using spells, curses and charms to mass production Carillons/Dug Weapons like the Percival.

Venenum Enhanced Strength
By channeling his Venenum output to his limbs, Willem can enhance strength to superhuman levels. In the past, he could use this ability to enhance his strength for much longer period of times, with his current damaged body, he can only handle short bursts. However, even with his body, Willem is still powerful enough to best most foes in hand to hand combat. He was also shown to be able to take on Timeres empty handed.

Venenum Enhanced Speed
By channeling his Venenum output to his legs, Willem can moves at speeds faster than human eyes can perceive. In the past, he was able to move like so for much longer periods of time and cross larger distances, however with his current damaged body, he can only handle short bursts of such speed.

Swordsmanship
Willem is a skilled swordsman. In his prime, he would double wield Carillons to take down his opponents. With his weakened body, he is still skilled enough to hold off a Leprechaun like Chtholly, however, just using a Carillon for more than a few minutes is enough to cause severe internal damage to his body. He now prefers to teach swordsmanship to Chtholly, Ithea, and Nephren’s at the warehouse rather than fight instead.

Tuning of Carillons
One of the many abilities that Willem had obtained on his quest to become a Regal Brave was the tuning of Carillons. He learnt it from skilled technicians due to him preferring to tune and adjust resistances and buffs on his Carillons in the heat of battle. Other braves usually don’t tune their own swords. He is very familiar with most Carillons/Dug Weapons and knows each of their personal quirks and unique abilities. He can instantly tell what a Dug Weapon's type is such as  'Kin-slayer, ' as well as what charms make up an individual Dug Weapon.

Just like how Lillia was talented in fighting and Souwong (later Great Sage) was talented in spell fabrication, Willem is extremely talented in tuning. A technician once remarked that "no other human could do what Willem can in terms of tuning", because Willem’s tuning is so fast, he can complete in minutes when normal technicians require days to do it. Due to this, Willem became known as the  'Black Agate Swordsmaster.’ 

At present, Willem is the only person alive who can tune Carillons and Chtholly herself likens his tuning skill to a "performance."

Beast Abilities - La Chanteuse
As a half-beast, Willem does have access to La Chanteuse's abilities. During the Battle of Corna di Luce, Willem effectively uses La Chanteuse's 'Sand Disintegration' ability to wipe out the Aurora and the Elpis Mercantile Federation's new weapon. His physical power was also enhanced and he can easily maneuver due to his body being healed by La Chanteuse's regeneration capabilities. However, he can only use these powers for roughly 5 minutes before the Beast half fully takes over his consciousness.

Trivia

 * Some might say he is over 500 years old, but as per definition of ageing (the process of getting older) and from the LN, he is recognized to be 18.
 * In episode 5 of the anime, Willem was shown to defeat multiple members of the Annihilation Knights hired by the nobility in Corna di Luce by utilizing coins as bullets. The same event in the light novel happened, however the outcome of it was very different. In the Light Novel, Willem did not actually engage in combat, but instead sat down on a wooden crate and negotiated with the members by demonstrating that there were Venenum users amongst them (namely Ithea), only disarming one particular member who attempted to shoot him with a pebble. After successful negotiations Willem and the group proceeded to the port as usual. Chtholly then remarks angrily that Willem was ‘in a battle stance ever since he sat down on that wooden crate’ and that he would’ve taken care of all fifteen beastmen in a mere 3 seconds if the situation became unfavorable. This clearly demonstrates that even with his heavy injuries, Willem’s strength is not to be underestimated.
