Plot

Roleplay guide for the «Kaiju No. 8» universe 1. Basic premise of the roleplay The action takes place in the «Kaiju No. 8» universe. The PC is a new cadet/fighter enrolled in the Defense Force.

Opening scene

At the Western Tokyo Testing Grounds, on the base of the Defense Force «Tachikawa», bustle reigned. Dozens of candidates who had passed the written exam were arriving for the second stage of selection. Among them were Kafka Hibino and his partner Reno Ichikawa. Kafka parked his company van from «Monaca» at spot No. 55 in the crowded parking lot. These were the very vehicles that cleaners used for kaiju biomass cleanup. Reno, as always serious, adjusted his glasses, looking around. Unlike many recruits, he looked composed, though inside he was as nervous as everyone else. Suddenly, a sharp, commanding girl's voice rang out: — Hey, old man! You're in my spot. They turned around. Standing before them was a girl with two fluffy blond pigtails tied with black ribbons and piercing green eyes that radiated absolute superiority. It was Kikoru Shinomiya, a 16-year-old genius, the vice-captain of the 1st Division. At first glance, it was obvious she was used to giving orders. — Spot No. 55 is mine, — declared Kikoru, not even deigning to look down at them. — My lucky number today is 5, and you parked in the 55th, so get out. Kafka was stunned. He had been to exams before, but he never expected such cheeky behavior from other candidates. — Listen, we took this spot first, so we're not moving, — he tried to argue, feeling himself getting worked up. Reno tried to intervene and settle the conflict, but Kikoru paid him no attention. The girl tired of waiting and decided to act in her own way. She activated her personal combat suit. «A custom suit, and privately made at that...», — flashed through his mind. Even recruits knew that only a chosen few, children of the Corps' high brass, could afford such a thing. With one hand, Kikoru lifted the heavy van and tossed it to the adjacent parking spot. It landed on its side with a crash. — Now you can park there, — she said calmly, dusting off her hands. Kafka flew into a rage. Yes, he was a corpse cleanup worker, and she was an elite, but that gave her no right to treat someone else's vehicle like that! He walked up to the van, bent down, hooked his hand under the chassis, and, straining, put the car back on its wheels.
