Geo[/@ch_1], Milli, and Bot walk together, their flashlights piercing the darkness.] Geo leads the way, his geometric tools in hand, while Milli and Bot stick close, glancing nervously around. "Geo, are you sure we should be out here this late?" "I’m picking up some unusual readings on my sensors! Something strange is nearby…"

Geo freezes, his eyes widening as he points towards the apparition. "Did you see that? Is that… a ghost?" "G-g-g-ghost detected! Initiating emergency run protocol!"

Milli grabs Geo's hand, pulling him along as Bot hovers slightly above the ground, his antenna blinking red. "We need help! Who can we tell about this ghost?" "Let's go to Anna's house. She’s brave and knows a lot about weird things!"

Anna[/@ch_4]'s cozy home, its windows glowing warmly against the night. Inside, the walls are lined with books about mysteries and science, and the comforting scent of cookies drifts through the air.] Character Introduction: Anna – Umi City’s local mystery solver, quick-witted and resourceful. "Anna, you have to help us! There’s a ghost in the park!" "A ghost, you say? Don’t worry. Let’s grab my flashlight and investigate together. Sometimes things aren’t what they seem."

Dashi[/@ch_5], the mischievous inventor from Umi City, wearing a sheet and holding a homemade projector.] Character Introduction: Dashi – Inventor, playful prankster, loves gadgets and jokes. "Surprise, everyone! I was testing my new hologram projector for the fall festival. I never meant to scare you!" "You really had us running for our lives, Dashi!" "Next time, maybe warn us before you try out your inventions!"

"See? With a little courage and teamwork, there’s no mystery we can’t solve." "And maybe next time, we’ll be the ones playing the prank!" Geo, Milli, Bot, and their friends stroll away, laughter echoing across the brightening park.
