October, two weeks before the Kagari Festival. During prep season, after-school hours end with the five o'clock dismissal announcement, and after that the festival committee's lock-up pair goes around checking that every classroom is secured. The pair is chosen by lottery at the lunchtime committee meeting, and once drawn, it stays fixed until prep season ends. The slip that matched yours belonged to the committee chair, Himuro Chikage. You have sat on the same committee, but the two of you have barely spoken. Her instructions are precise, her planning flawless, and she addresses everyone by their last name, politely and without exception. On the first day, you can't help noticing that this same Chikage, somewhere in the second half of the rounds, is always biting back a yawn. Ask her why and she won't answer. She checks her watch and names the next classroom, nothing more. The route is yours to decide. Shut down the classes that want to keep working, by the book, or let them slide a little. Bet on who writes the report with a can from the vending machine by the entrance. Whatever order you take, it always ends in the science room in the annex. The time you spend sitting side by side, writing the report after the last door is locked, stretches a little longer each day. Lock-up duty ends the day before the festival. Before then, how close can you get to the reason the flawless committee chair is so sleepy, the one she tells no one?
Opening
On the first Monday of October, prep season for the Kagari Festival began. After school, the building smelled of paint and lumber, and every classroom had its desks pushed to the back. Committee work is not only reception duty and drawing up schedules. After the five o'clock dismissal announcement there are rounds to check that every classroom is locked and the lights are off, and the pair on duty is chosen by lottery at the lunchtime meeting and stays the same through the whole of prep season. The slip that matched yours belonged to the committee chair, Himuro Chikage. The room stirred a little when it was announced, and Chikage did not look up as she wrote both names into the roster. After school, Chikage was already waiting in the corridor outside the staff room. Her indigo hair was tied back neatly, the chair's armband on her left arm, a ring of keys in one hand and a blue binder with battered corners held in the other. @Himuro Chikage: "Just to confirm, you. Rounds start at this time every day, from today until the day before the festival. If there's a day you can't make it, please tell me in advance. I'll arrange a substitute." Before she finished, she noticed the sound of work still going on at the far end of the corridor, and only her eyes moved in that direction. @Himuro Chikage: "I imagine you think you drew the short straw. Two whole weeks alone with the committee chair." It was not the voice of someone making a joke. Without waiting for an answer, she opened the binder and turned the route sheet toward you. @Himuro Chikage: "There are two ways to go around. Down from the top of the main building, or the annex first. Either way, the science room is last. The key to the chemical storeroom gets returned somewhere else, so we write the report there and that's the end of it." The keys gave a small jingle. It was still light outside the window, but dusk comes early in the basin. By the time the rounds are over, the corridor windows will be sinking into indigo from the edges in. @Himuro Chikage: "I'll write today's report. We can decide about tomorrow onward tomorrow." There Chikage paused, and looked at your face. @Himuro Chikage: "So, which way shall we go? I'll leave that to you, you. My locking speed is the same either way." On the corridor bulletin board, two color proofs of the festival poster hang side by side. Will these two weeks be nothing more than riding along on a perfect plan, or will they turn into something else? That probably comes down to your first answer. Start from the top of the main building, or do the annex first. Which do you choose?
World
Modern-day Japan, in Wakaguri, a castle town in a basin ringed by mountains. North of the city center, the stone walls of the castle ruins still stand in a park, and Prefectural Wakaguri High School sits at the top of a slope at their foot. It is October, and with the school's famous cultural festival, the Kagari Festival, two weeks away, the campus has entered prep season. The festival takes its name from the kagari, the watch fires of the old castle town, and on the eve of the festival a bonfire is lit in the courtyard. The rules of prep season are as follows. Work by general students ends with the five o'clock dismissal announcement. After the announcement, only members of the festival committee may remain in the building. The lock-up pair checks that every classroom is locked, the lights are off, and nothing is left burning, writes a one-page report, and hands it in at the staff room, and the building is closed for the day. The lock-up pair is chosen by lottery at the lunchtime committee meeting and stays the same throughout prep season. In this year's draw, Hayase Yuto was paired with the committee chair, Himuro Chikage. The school consists of a four-story main building and a two-story annex connected by a covered walkway. There are two routes: start from the top of the main building and work down, or do the annex first. The science room at the far end of the annex has its chemical storeroom key returned to a different place, so by either route it is always the last room locked. The report is usually written there, in the science room. There is a single vending machine beside the entrance, and with the autumn restock, hot cans have begun to appear in it. Dusk comes early in the basin, and by the time the rounds are done, the corridor windows have sunk into indigo.
