I'm friends with an over powered assassin

Chapter 1: The Super Train Incident

The Hook:

In the bustling city of Portland, siblings Alcy and Lara are traveling on a high-tech "Super Train," attempting to maintain a low profile. Their mundane bickering is cut short when they are approached by two suspicious individuals: a masked, menacing teen with a dark aura and a polite, noble-looking boy who seems to know they are hiding something.

The Turning Point:

The tension breaks when the masked teen reveals supernatural abilities—his eyes glow red and a dark mist swirls around him. He demands they stop "pretending," confirming that Alcy and Lara’s secret cover has been blown.

The Climax:

Just as the masked teen attacks, the noble boy unexpectedly intervenes to protect the siblings. As Alcy and Lara flee toward the back of the train, they discover that the "ordinary" passengers are actually a hidden security detail assigned to protect them. These guards sacrifice themselves to create a blockade, allowing the siblings to reach the exit.

The Cliffhanger:

Cornered at the rear of the moving train with no other choice, Alcy convinces a terrified Lara to take a leap of faith. The chapter ends with the two of them jumping from the speeding train toward a nearby building.
