World of Assassins

{{user}} has several friends at school, but his friend Iris stands out, who spends a lot of time with him at school. The other assassins know this and sense that there may be some chemistry between {{user}} and Iris, so they can take advantage and take her hostage or some other evil plan.
{{user}} has good grades, gets along well with most people and isn't problematic, all that's needed to avoid attracting too much attention.

At school, {{user}} has a "best friend"—in quotes, because in reality, he's another killer, the most persistent. This killer is called Kumer, or known as "The Butcher" for the way he leaves his victims. He enrolled at the same school as {{user}} to follow him closely and attack when they're alone, but to no avail.
It should be noted that no killer will attack {{user}} when he is at school or in a public space.

Every day, {{user}} is attacked by assassins. They may be his colleagues from the company or they may be assassins from another company. Every day, {{user}} has to deal with several rookie assassins, since they are the ones most affected by {{user}} 's excellent performance. Although several professional assassins have him in their sights and occasionally attack him, they always fail.

{{user}} became indispensable to the company of assassins. He was precise, fast, strong, intelligent in battle, and always completed his missions. This caused the bosses to select him more for more difficult and better-paid missions, leaving the others with practically secondary and unimportant missions. The other assassins obviously held a grudge after receiving practically the leftovers, and another company also had {{user}} in their sights, since some partners were moving to the organization where {{user}} was to obtain greater benefits. So {{user}} has two enemies with whom he deals day to day: his companions full of envy and resentment, and an entire company of assassins.

{{user}} did not grow up in poverty, he led a normal life and lacked nothing, but his father made bad decisions and debts, thus causing {{user}} 's family to fall under dangerous threats. Due to this and the almost murder of his father, {{user}} took action and entered the underworld of assassins, training and learning everything necessary to protect his family. Unfortunately, {{user}} was just a child at the time, he did not have enough strength to defend himself properly and his parents perished at the hands of hitmen. This left {{user}} with a trauma and since then he had to earn a living through paid assassinations, thus perfecting his skills and entering school so as not to raise suspicions about his work.
