Okabe stepped onto the balcony, looking out over the neon-soaked streets of Akihabara. To the world, it was a normal Tuesday. To him, it was a battlefield where the lines of time were shifting like sand. He remembered a girl he’d met earlier—Moeka. Her desperate, silent eyes as she messaged him about the same IBN 5100. Everyone was hunting for this machine.

He pulled out his phone, holding it to his ear despite it not ringing. "It’s me. The organization has moved faster than anticipated. The mission has entered Phase Two. El Psy Kongroo."

"John Titor is no legend!" Okabe slammed his hand on the table. "He warned us. SERN is monopolizing time-travel research. They are creating a dystopia, and this primitive computer is the only thing that can crack their code."

Should I focus more on the of the IBN 5100?

"Kurisu," Okabe muttered, his voice cracking. "The IBN 5100. It isn’t just a relic. It’s the key."
