■ Plot Summary
A legendary hacker, Shadow Code, renowned across the Internet, lurks in this ordinary town.
Shadow Code is an elusive hacker who only follows his own rules and takes on cases based on his own aesthetics and preferences. Once he accepts a case, he will always be able to fulfill the commission perfectly with his profound technical knowledge and his superbly resourceful reactions, and of course, the reward he receives is not low at all.
One night, Shadow Code receives an anonymous letter containing a puzzle test. Solving the puzzle is not difficult, but what Shadow Code doesn't expect is that the events that follow this letter will lead him to the greatest challenge of his hacker career.
■ Character Introduction
Agent “Saku”
who belongs to the mysterious organization LUNA.
Once an abandoned orphan, she was then adopted and raised by the organization. Having mastered a wide range of skills taught within LUNA, she earned her title and became one of the most elite agents in the organization.
Despite being good at various kinds of weapons and martial arts, beneath the cold-blooded agent identity lies a gentle, kind and compassionate soul.
Phantom Thief “Lucy”
To become a legendary phantom thief, she constantly trains in parkour, wall-running, and all kinds of acrobatic techniques. Her physical abilities are exceptional, but she's hopelessly absent-minded, always messing up at the worst possible moment and landing herself in life-threatening situations. Fortunately, luck is always on her side, and she somehow manages to escape every crisis unharmed.
Unfortunately, she's an utterly incompetent thief—every heist ends in failure, leaving her so broke that she survives on nothing but toast.
Unlike the discreet image of a true phantom thief, she loves flashy entrances and dreams of becoming famous. Mention a legendary treasure, and she'll fall for the bait every single time.
“Misoka”
A mysterious young woman whose identity remains completely unknown. For reasons of her own, she has set her sights on you.
Physically, she's no different from an ordinary person, but her hacking skills rival the protagonist's. Serious, fiercely competitive, and quietly confident in her abilities, she thrives on taking on difficult challenges.
Misoka is completely absorbed in honing her craft, showing little interest in anything unrelated to pushing her skills even further.
■ Hacker's Daily Life
Armed with these hacking skills, Shadow Code is going to experience a thrilling adventure with the mysterious client—Agent “Saku”, helping her get rid of a mysterious organization and ultimately complete an impossible rescue mission.
Except for the main mission, there are also various events that may happen in the town. You are free to act according to your willingness and solve the multiple problems that occur in the town.
Solving events not only enhances Shadow Code's reputation but may also gain special "rewards", or may even meet new friends, which unlocks entirely new story arcs.
