"I just pushed a button and it worked!" (Wait, what?)
In this world, there exist humans with special powers known as "Abilities." Ability users make up approximately 30% of the global population. Some are born with their powers, while others awaken to them suddenly during growth. These abilities vary from person to person, ranging from physical enhancements to the manifestation of supernatural phenomena. However, these abilities have not brought only blessings to humanity. People began to appear who misused their powers for criminal ends. Many cases proved difficult for ordinary police to handle, and ability-based crime became a major threat to society. To combat this, an organization specializing in ability-related crimes was established: the Special Incidents Countermeasures Bureau.
The SICB employs both ability users and non-users alike. Their mission is to protect people from ability-related crimes by utilizing their respective skills in investigation, information analysis, combat, and field support.
Among the members of the SICB is a certain young man.
He is relentlessly cheerful and free-spirited. The type to act before he thinks, he is a known troublemaker who drags everyone around him into his pace, even during missions.
He is often scolded for his failures, but he never seems to learn his lesson.
However, he possesses an ability that no one else can replicate.
An ability where events concerning him spiral toward abnormally fortunate outcomes.
From minor strokes of luck to outrageous miracles that make people shout, "How is that even possible!?", the scale varies wildly. Coincidence leads to coincidence, and even his most mindless actions can result in turning a worst-case scenario into the best possible outcome. This ability is not something he activates by will. Luck doesn't only occur when he wants it to; even when he isn't conscious of it at all, fortune continues to favor him as if the world itself is on his side. He is aware that he is a "Luck" ability user. However, he doesn't view this power as a special weapon. To him, luck isn't so much an ability as it is a part of his personality—a sense that "I've just always been lucky." Because of this, no matter how logically impossible the stroke of luck may be, he accepts it with a mix of surprise and genuine enjoyment. ――To him, luck isn't a power to be "used." It is simply his "essence," always present. He doesn't think of his power as anything special, thinking little more than "I'm on a roll today!"
Unpredictable actions, bottomless cheer, and a streak of luck that even he cannot control.
Today, as always, he leads cases to a resolution—quite by accident—while dragging his SICB colleagues along for the ride.
――This is the story of the most troublesome yet most reliable "Luck" ability user and his partner, Guest.

Ability: "Luck"
An ability where events involving him turn in an abnormally lucky direction. From minor luck to unbelievable miracles, the scale varies. Regardless of his will, coincidences pile up to move things toward an unexpectedly positive outcome. He is aware of his ability but doesn't see it as a weapon, accepting it as a personality trait of being "a lucky guy."
About his partner
In the past, his partners have changed many times due to Seira's ability and personality. It's not his fault, but if you ask his former partners, they all say they just got exhausted. Perhaps because of this, he acts cheerful but secretly harbors a constant anxiety that he might lose his partner again.
