A comedy heist crew! Any security system turns into a joke before their magic!
On October 31st, a major Manhattan bank is bustling with customers in costume. The stiff branch manager, Guest, takes pride in the ironclad security and scowls at the festive atmosphere. Just before closing, a quartet dressed as a Jack-o'-lantern, a witch, a vampire, and a ghost burst in, declaring, "Nobody move!" However, the customers, thinking it's a performance, break into applause. The four are best friends from college who planned this heist as a "final memory." Yet, during the act, biometric scanners, alarms, and double vault doors all start opening on their own for no apparent reason. Three of them are ecstatic, shouting "We're so lucky today!", but Winnie, dressed as the ghost, is secretly moving her fingers under her sheet. She is a real witch, and her target is an ancient magical artifact sleeping deep within a safety deposit box. Without revealing her identity to her friends, she is secretly helping everyone with magic. Guest notices the state-of-the-art systems collapsing in inexplicable ways and begins to suspect there is something more than "luck" at play among the four. S.W.A.T. teams arrive, but the building is so full of costumed guests that they can't tell who the robbers are, leading to total chaos. As the night deepens and the witch's power reaches its peak, Winnie finally gets her hands on the artifact. At that moment, Guest learns her true identity, and the story heads toward an unexpected conclusion.
29 years old. Jack-o'-lantern / Leader. A former bank systems engineer. She can't see a thing through the pumpkin head and keeps bumping into walls and pillars. Her catchphrase is "Just as planned!" She insists on this even when things aren't going according to plan at all. Public Face: The reliable big-sister figure who claims her plans are perfect. She constantly smashes into pillars because of her lack of visibility. She's the caretaker type who prepares lunch boxes for everyone. Hidden Side: Actually timid and socially anxious. She's afraid of people's gazes, so the pumpkin head is a "charm" that lets her act tough. Since graduating college, her friends have been moving on to different paths, and she fears most of all that "this might be the last time we can all get together." The heist is just an excuse; her true goal is to make the best memory of doing something stupid with her four friends. To that end, she spent a year crafting a meticulous plan.
27 years old. Witch costume. Public Face: The upbeat mood-maker. A beginner who learned lockpicking from videos. Her large hat frequently gets caught on doors and shelves. Every time a door opens on its own, she praises herself, saying, "My talent has finally awakened!" Hidden Side: Her three friends all have specialties (Mira has brains, Victoria has drive, Winnie has a mysterious charm). Roxy secretly harbors a complex, feeling she has no real talent of her own. That's why she chose the role of the bright one who keeps the mood up. Her claim that her "talent has awakened" is a sincere wish. She is the heart of the group, remembering everyone's birthdays and favorite foods. Heist Commitment: For this plan, she worked part-time late at night for six months to buy tools. She practiced at her own front door and accidentally locked herself out 12 times. She's loved witches since she was a child and wears a witch costume every Halloween.
28 years old. Vampire. Public Face: A pretentious lady character. However, she's terrible with blood and turns pale even at the sight of tomato juice. Her clip-on fangs often fall out, and she neglects her lookout duties while searching for them. A worrier whose catchphrase is "Maybe we should just go home." Hidden Side: Actually a daughter of a prestigious family. Raised to be "perfect" since childhood, her pretentiousness is both a habit and a suit of armor. This heist is the only "bad thing" she's ever done in her life. Only when she's with her best friends can she be her true self. She likes the vampire costume because "it feels like I can be free only at night." Secret of her Worrying: Her worries are always logical and correct. She compiled 47 worst-case scenarios in her notebook, like "What if the alarm goes off?" or "What if the door won't open?" However, thanks to Winnie's magic, not a single one of her worries comes true. Every time, she's left deflated, thinking, "...Wrong again." Frustrated by her streak of bad luck, she's started trying to make her predictions come true on purpose.
26 years old. Ghost / Real Witch. Public Face: A petite, talkative, and airheaded mood-maker. She never stops talking, even inside her sheet. Every time she uses magic, she awkwardly covers it up by saying, "That was just a coincidence!" Sometimes her magic goes haywire when she sneezes, turning an alarm into a pumpkin. Hidden Side: Born into a lineage of witches. As a child, friends she showed magic to became afraid and left her, leading her to believe that "if my true identity is revealed, I'll lose my friends." Her non-stop cheerful chatter is a desperate attempt to make her magic look like a "joke." Magic leaks out when her emotions run high: little stars fall when she cries, and nearby objects float when she laughs. The Artifact in the Safety Deposit Box: The "Seal Key" that locks away a witch's powers. She wants to live as a human with her best friends. The three friends she met in college were the first to treat her like a "normal friend." She is prepared to throw away her magic to protect this bond. But before sealing it, she wants to use her last bits of magic to make their "final memory" a success. That is why she is helping the heist with everything she has.
S.W.A.T. Team. The building is full of costumed guests, making it impossible to distinguish the robbers, and the scene is in total chaos. Despite their serious efforts, their guns turn into toys and the sound of soothing cat purrs comes through their radios.
Excited ordinary customers who came dressed in Halloween costumes.
