The Observer Beneath the Lighthouse

On the north shore of the Uninhabited Island, at the independent observers' camp, Ryuen Kakeru sat on a jagged rock. The cold light from his terminal screen reflected on his face, casting a small shadow from his eyelashes, which trembled slightly in the sea breeze. Before him lay two observation reports yet to be submitted: the first regarding the Shared Pool Allocation model for Group 12 in South Coast Area B, and the second a comparative analysis of the efficiency of material dispatching across all groups during the storm warning. Sakagami had tasked him with submitting two reports, and he could have stopped at two—no one had asked him for a cross-sectional comparison, no one had asked him to annotate the precise timing of dispatch delays for every group, and no one had asked him to include a scoring matrix for emergency evacuation routes in the appendix. Yet, he had already completed twelve tables and was currently working on the thirteenth. It wasn't about currying favor or seeking redemption; it was an instinct honed in the White Room—once you have no cards in your hand, you memorize the face of every card in play.

He replayed the communication logs from all six camps on the island during the storm, marking the start and end times of every signal interruption and the delay between every material dispatch order and its response. Some data was uploaded automatically by real-time monitoring points, while some he had recorded frame-by-frame himself, hunkered down on the lighthouse observation deck with binoculars. One group from Class C had an error margin of thirty-four percent between their estimated and actual freshwater consumption, far exceeding the twenty-percent red line set by the school. They hadn't reinforced their distiller before the storm hit, the filter element had become clogged with silt, and two members had argued for fifteen minutes in the rain before reassigning their tasks. He inserted this record into the final section of the Shared Pool analysis model, adding a single line of commentary: "Material dispatching without attached justification for allocation shows an average delay four times longer than that of Group 12 during the passage of the low-pressure trough. The highest sources of error all point to the same group's failure to activate Shared Pool weighting."

As he finished the last stroke, he paused and looked up at the black sea beneath the lighthouse. A few minutes earlier, Ishizaki had been crouching by the Weather Station, observing a bird's nest that had been blown out of its tree by the gale. He had used his carry-along shovel to lift it back into the branches, tucking in some dry leaves for good measure. Ryuen had watched this through his binoculars, his fingers pausing involuntarily on his log. He flipped back to the first observation report and added a supplementary note at the end of the appendix: "The behavior of certain observed subjects possesses a residual value that cannot be quantified. It is recommended that this not be included in the current scoring, but left for subsequent observation."

He didn't write Ishizaki's name, nor did he mention the bird's nest. But the index number for that supplementary note and the data regarding the duration of Ishizaki's sampling at the Water Intake last night happened to fall on the same line.

His terminal vibrated. A system notification popped up: "Independent Task Item 2: Submit two observation reports. Deadline: June 7th, 00:00. Forty minutes remaining." There was also a private message from Sakagami, phrased more directly than the system notification: "The first draft of the literature review has been received. There are two typos, and the year cited for the Shared Pool clause in the third section was written as this year. You may submit the final version by June 9th after corrections; it will not be counted as late." There was also a voicemail marker from Ishizaki, sent just after the storm had passed. At that time, communication signals hadn't fully recovered, and the audio was chopped into fragments and stitched back together; amidst the intermittent phrases, one could vaguely make out "sports drink," "half a bottle left," and "placed next to the distiller." He hit play, listened to the entire fragmented message, and did not reply.

He shut down his terminal, stuffed his tablet and binoculars into his waterproof bag, and stood up from the rock. The white light of the lighthouse swept behind him, casting his shadow long across the jagged reef. Ishizaki had said he wouldn't climb the wall again, but as he watched him lift the bird's nest with his shovel by the Water Intake this afternoon, Ryuen felt that he was the one still climbing the wall. Ishizaki had already climbed over; he was still wandering outside. He slung the waterproof bag over his shoulder and walked back along the gravel path leading from the north shore to the lighthouse. The shrubs on both sides of the path had been battered by the storm, and the roots of several old trees were exposed to the soil, but the foundation of the lighthouse remained unmoved. As he reached the base of the lighthouse, he suddenly remembered the last time Sakagami had stopped him in the hallway after attending a Disciplinary Committee meeting before his retirement, telling him to open the records of the Old System. At the time, he had felt the old man was using ancient history to beat him down; now, standing alone under the lighthouse, he finally realized that Sakagami had never intended to beat him down—Sakagami had simply placed the key at a junction he was bound to pass, waiting for him to walk far enough to turn back and pick it up. Shared Pool Allocation. Ryuen Kakeru's literature review, specifically the third section, was a reinterpretation of that very frozen clause.

At exactly midnight, the two observation reports were submitted on time. He didn't go to sleep immediately; he opened the chat window with Sakagami and typed a line: "The year typo in the third section of the literature review has been corrected. I found a possible trigger point in the storm data regarding the activation conditions for the collaboration score Immunity in the Old System's frozen clauses. If possible, I would like to submit an independent argument before the end of the first phase." He clicked send. Then, he turned off his terminal, lay on the cot with his hands behind his head, and watched the Tin Roof being sliced into alternating stripes of light and shadow by the lighthouse beam. A few minutes later, the phone screen lit up. Sakagami had replied. No pleasantries, no praise, just the tone he was familiar with: "Correcting the typos is fine. Handle the argument yourself; don't bring it to me, submit it directly to the school's backend. You have five days." He placed the phone beside his pillow, didn't reply, just turned the screen face down, and closed his eyes. The white light of the lighthouse continued to sweep over the Tin Roof every ten seconds, at the same frequency as the Group 12 camp on the south shore.
