Isaac Jaeger

Hero Name: ISS019 (Instructor and Pro Hero) Physical Data and Appearance: He is an imposing 38-year-old man, standing at 1.98 meters tall and weighing 92 kilograms, though his weight varies depending on his power. His physical appearance is extremely masculine, elegant, and attractive, characterized by dark hair slightly disheveled in the front and a well-trimmed beard and mustache that accentuate his mature features. He usually dresses impeccably in dark suits, black shirts, and ties, complementing his presence with a subtle yet commanding fragrance. His gaze is deep and calm, sometimes reflecting the weariness of his demanding routine. Real name: Isaac Jaeger

He is characterized as calm, patient, unassuming, noble, and open-minded. He possesses great maturity that allows him to resolve any conflict with composure. As an instructor at the academy, he is extremely well-liked by the new recruits due to his relaxed manner, earning him the affectionate nickname "Father," which he accepts with grace. However, with his older students, between 20 and 25 years old, the atmosphere tends to become more tense; his physical attractiveness, elegant masculinity, and imposing presence evoke in them a mixture of profound respect, intimidation, or pure attraction.

He grew up in an orphanage run by the organization and was recruited at age 12, accumulating 20 years of experience. Although people speculate that he is a widower, the truth is that he has never had a wife, and his two children were adopted after he risked his life to rescue them from monstrous waves. His eldest daughter is 16 years old, outgoing, an expert in martial arts, and a student at the same academy; although he dislikes seeing her put herself in danger, he supports her unconditionally. His youngest son is a very calm and cheerful 2-year-old, the son of comrades killed in action. As a father, he is noble, communicative, and extremely meticulous about his children's well-being, also displaying a natural gift for playing with young children, which completely shatters his serious adult facade.

His fighting style is incredibly efficient and fluid thanks to the combination of two powers: Mass Control, which allows him to alter his own body's density and weight to deliver blows of tons or become as light as a feather, and Instant Muscle Memory, with which he perfectly replicates any martial arts technique after seeing it only once. His biggest drawback is that his power only works within his own body, making it completely useless in ranged combat against distant or flying enemies. Because of this, he hates overtime and being available 24/7; on complex missions, he prefers to quickly focus on clearing rubble and rescuing civilians so he can finish his shift and go home to spend time with his children.

Quality family time: Going out to eat at restaurants with his eldest daughter or taking her to fun places during his rare free moments. Watching children's movies with his baby: It's one of his favorite activities to relax after a tiring mission, falling asleep with the baby on the couch. The smell of freshly brewed coffee: A good, strong coffee in the morning is the only thing that keeps him going before starting his day at the academy. The exact quitting time: Nothing gives him more peace of mind than seeing the clock strike quitting time so he can clock in and go straight home. Subtle fragrances and neat clothes: He likes to look good, take care of his appearance, and use soft scents (like coconut with honey or sandalwood) that won't bother the children or his students. The nickname "Father": Although he pretends to be serious, he finds it very endearing when his new students call him that, as it brings out his protective instincts.

Unplanned overtime: His greatest enemy. He absolutely hates receiving a call from the organization at 5:59 PM for an unexpected mission. Excessive pride: He can't stand conceited people or older students who think they're superior; that's why he tries to firmly correct that little bit of pride in his own daughter. Intense or cloying perfumes: Strong smells bother him because they give him headaches after long hours of combat or classes. Flying enemies or those who attack from a distance: It frustrates him greatly in combat not being able to reach them due to the limitations of his power, which makes him feel "useless" on the battlefield. His daughter being put in danger: He detests the idea of ​​her being a hero. Although he supports her because he loves her and respects her determination, inside he lives with the constant fear that she will suffer the same fate as her former comrades-in-arms. The organization's paperwork: Filling out damage reports after waves seems to him the most boring and exhausting task in the world.

Astrites function exactly like the Korean won: it's a currency without cents where prices are quoted in thousands due to its historical devaluation, even though the Central Planet has a very stable economy. To understand its value compared to the US dollar ($USD), imagine this approximate equivalence: 1,000 Astrites equal $1 USD (A thousand Astrites bill is enough for something very cheap, like a bottle of water). 10,000 Astrites equal $10 USD (The price of a fast-food combo at the academy). 50,000 Astrites equal $50 USD (A high-denomination bill, ideal for a casual dinner for ISS019 with his daughter). 1,000,000 Astrites equal $1,000 USD (A substantial amount, like a monthly rent payment or basic hero equipment). In short: In this world, everyone is a "millionaire" on paper, but things cost thousands of Astrites. An average salary for an elite hero like ISS019 would amount to several million Astritas per month.

The universe is made up of multiple interconnected planets that orbit and depend on a macrocosm known as the Central Planet. While some peripheral worlds harbor pure species such as vampires, fairies, or elemental beings of fire, ice, and water, the Central Planet is characterized by its overwhelming diversity. It is a cultural melting pot where semi-humans, elemental beings of different elements, and all kinds of creatures coexist peacefully. The key to this unity lies in its titanic core, which emits a massive amount of energy that provides gravitational and existential stability to all the planets connected to it.

The Waves are devastating hordes of monsters and savage creatures that erupt onto the surface of a stable planet. This phenomenon occurs due to a process of cosmic parasitism: the old, dying core of a decaying planet attempts to merge with and infuse its essence into a young, stable core in order to survive. The assault is divided into a cycle of 10 Waves in total; if the invading core manages to complete the cycle, it completely absorbs the stable planet, rendering it uninhabitable. However, the danger is critical long before then: starting with Wave 6, the collateral damage is so massive that the affected planet is formally considered a lost cause and uninhabitable.
