Episode Arc: ‘Secrets Beneath the Sakura Tree’
The story starts with Naoya Shimizu, a curious second-year high student, staring out his clubroom window one warm April day. He’s always wondered why the old sakura tree behind the school gym is off-limits, ringed with an iron fence that’s grown rusty with time. The teachers shut down all questions. They say it’s for ‘student safety,’ but Naoya isn’t buying that.
His friends think it’s just teachers being strict. Miyako, his best friend, rolls her eyes when he brings it up. ‘Don’t you ever get tired of hunting for ghost stories?’ Ayumu, the quiet girl who always checks library records, adds softly, ‘Some secrets don’t want to be found.’ But is that really true?
At dusk that day, Naoya and Miyako hear a soft cry coming from behind the gym. Together, they lift the fence enough to slip through. The ground under the tree is smooth, too smooth—almost as if someone comes here all the time. They find scratch marks and letters carved deep into the roots: names and dates, weird shapes, a small pressed origami crane. Whose were these?
Ayumu tags along the next time, notebook in hand. She matches one of the names, Mei Tanaka, with a girl who moved away a decade ago after a sudden disappearance. The trio starts digging through old yearbooks and chat up sleepy janitors and club teachers. With every lead, the rumors change: a lost lover’s pact, a cheating ring, a staff ghost, someone hiding exam answers, or worse. Which would you believe?
They notice someone else is watching them—a boy in the shadows, Ryuto, a new transfer whiz at riddles and always with earbuds. He coldly warns them off later. ‘Some lids stay heavy for a reason. Watch where you dig.’ Is he a friend, or hiding something himself? Miyako whispers late that night, ‘Why’s Ryuto always near? Did he leave those carvings?’ But Ayumu disagrees, convinced Ryuto’s protecting something—or someone.
Hunted by night teachers and pranked by a sly student council head who jokes there’s treasure underground, the four get drawn together. Suspicion shifts between them and huddles start late under running club sirens, smells of yakisoba leftovers echoing from the gym. If you found your school’s wildest secret, would you keep it safe?
The clues lead to a faded photograph, seven people under that same sakura tree, grinning wide. At the moment they line up the photo with carvings near night’s edge, dogs bark from nearby houses, and heavy rain begins. They dig at the center root, uncovering a small tin box.
The episode or arc ends as they pry the lid open, faces flickering by flashlight, just as the dean’s voice calls from down the corridor—and a thin diary slips from Naoya’s shaking grip.
Before the secret’s words can be read, the rain washes the last hints of soil from the buried box. The story fades on their shocked faces, a secret monster either asleep or waking below ground.
