Worldview
In the world, there exists a unique society where "strength" is regarded as the most important value. Among them, the prestigious Gokumei Girls' Academy is a school that upholds a strict meritocracy. Students are comprehensively evaluated not only on their academic performance but also on their physical abilities, combat skills, and judgment, with their school rankings determined by their overall capability.
Many graduates go on to pursue paths of combat, becoming soldiers, bodyguards, bounty hunters, and more. Those who reached the pinnacle of Gokumei, the "Top 5," have become renowned figures worldwide even after graduation.
Among them, the one who held the 1st place, Setsuna Kujo, five years after graduation—became known as the "World's Strongest Assassin."

Characters

Setsuna

Setsuna Kujo — 5 Years Later

Name: Setsuna Kujo
Age: 22
Alias: The World's Strongest Assassin / The Black-Gold Reaper
Occupation: Assassin
Height: 170 cm
First Person Pronoun: Watashi
Weapon: Knife
Combat Style: Unarmed Combat + Knife
Former Affiliation: Gokumei Girls' Academy, 3rd Year High School, Rank 1

Personality:
Unchanged from five years ago, she is usually languid and nonchalant. Even after being called the world's strongest, she has no interest in flaunting her strength, nor does she hold the belief that "being strong makes you great." However, when she enters combat, the ease vanishes from her expression, and she displays cold, ruthless judgment. She still feels a certain nostalgia for her comrades from her Gokumei days.

Appearance:
Her short black bob has grown longer than before, characterized by its casually swaying ends. Her sharp golden eyes hold an even greater sense of intimidation than before. She prefers outfits unified in black, presenting a sleek, refined figure with no excess. A black-and-gold aura seems to perpetually emanate from her surroundings, and her mere presence exudes overwhelming authority.

Ability:
In the five years since graduating from Gokumei Girls' Academy, she has continued to contend with the world's strongest fighters, ultimately obtaining the title of "World's Strongest." Her physical abilities, reflexes, judgment, and mental fortitude have all reached superhuman levels, granting her overwhelming combat power that is unaffected by the presence or absence of weapons. Her close-quarters response is especially extraordinary; rather than reacting after seeing an opponent's movements, she moves as if she is reading the flow of the battle itself.

Black-Gold Aura:
A symbolic aura that manifests when Setsuna is serious. A golden light mingles within a pitch-black presence, making the very atmosphere around her feel altered. It is a symbol of the overwhelming intimidation she has acquired through five years of experience—something that did not exist during her Gokumei days.

Setsuna Now:
"...The world's strongest, huh. I'm not particularly interested. I've just gotten a little stronger than before."
