Chapter 6 — Tokyo

Tokyo, Japan. Shinjuku. November 14th.She had not called anyone in Delhi.This was the hardest decision she had made so far — harder than the night flight, harder than the server room, harder than watching Arjun's face on a video filmed six days before he died. She was a Delhi Police detective. She had resources, colleagues, protocols. The correct procedure, by every measure of her professional life, was to bring this to her unit, share the evidence, request international cooperation.Arjun's note had been clear: do not contact the police in any country. Not yet.She understood why better now. The UK private security contractor in Vayu's client list — whoever had KAVACH access in the UK was connected to intelligence services. If she went official, the information would travel through channels that had already been compromised. The investigation into KAVACH in 2020 had been killed by a tip. She did not know which channel the tip had come from. She could not risk another one.She flew on a tourist visa.She told the hotel in Bengaluru she was extending her stay.She told her unit she was still in London, managing estate matters. It was the kind of lie that would hold for a week.She had, she estimated, a week.Tokyo in November was cold and precise, the city doing the thing it did — moving millions of people through an infrastructure that worked because everyone in it had agreed to make it work, a social contract rendered in train schedules and traffic patterns. She found the address from Arjun's contact file: a building in Shinjuku, a co-working space on the seventh floor called Nexus Connect.The contact's name was Kenji Watanabe. Tech journalist, formerly of Nikkei, now freelance. His publication history: twelve years of tech industry coverage, two major exposés on surveillance technology sales, one story that had caused a parliamentary inquiry in Japan that had gone nowhere.He was waiting at a table by the window when she arrived.Forties, compact, with the watchfulness of someone who had spent a career around people who wanted information and had developed a specific calibration for it: trusting no one as a default, but adjusting from there."You're Naina," he said. Not a question."Yes.""Arjun showed me your photograph," he said. "A year ago. He said: 'If I can't come and I send my wife instead, she's the one person you can trust completely.' " He looked at her steadily. "Are you here because he can't come?""I don't know yet," she said. "I need to know what you know."He looked at her for a moment. Then he ordered two coffees from the counter in Japanese and sat back."I've been tracking KAVACH for three years," he said. "The Japanese angle: one of the four government clients in Vayu's system is a Southeast Asian government that uses the product to monitor Japanese journalists and activists in Tokyo. Three reporters I know personally have been compromised. One of them—" He stopped. "One of them was killed in a car accident eight months ago. The official finding was driver error. I've been trying to prove otherwise for eight months."
