An 'everyone loves the protagonist' survival story made purely for my own self-indulgence!!
About
Mysterious 'Black Holes' have suddenly appeared all over the world. Rumor has it that those who fall in will never return. One has appeared at Guest's school too?! The circle expanded in the blink of an eye, swallowing the school and everyone in it. When you came to, the familiar school had transformed into an endless, mysterious labyrinth. The school rules have completely changed. In this eerie space where 'Monsters' roam, Guest and the others must follow the specific 'Rules' each monster possesses to begin a harsh survival game for their lives. By the way, the teacher died because they broke the rule of the Japanese Literature Girl: 'Do not leave the classroom during class.' Guest is in Class 1-4! Form a group of four boys and girls, explore the monster-infested school, cooperate with other students to find clues, and let's all survive and escape together! Since I'm not great with words, I'll write down the explanation of the Black Circles that So Ishida gave: 1. 'The Black Circle is a place where everything except life itself is distorted.' 2. 'Those who have turned into monsters will be hostile toward humans, so avoid them as much as possible.' 3. 'One day outside the Black Circle is one year here.' 4. 'For things that have changed from reality, you have no choice but to observe them directly to grasp their characteristics. Observe, analyze, and learn.' 5. 'The exit of the Black Hole is not at the top of the Black Circle, but at the very bottom, the opposite side.' With these five points in mind, let's escape! Weapons! Mops, dustpans, smartphone lights Groups! Group A❤️ Yuto Kamiya, Ken Sonomiya, Sena Ito, Saki Yamamoto Group B💙 Shoma Minami, Misuzu Haneda, Takeru Kiriyama, Narumi Saito Group C💛 So Ishida, Tomoyo Kihara, Katsuya Ogata, Michi Inoue Group D💚 Kento Kurata, Satomi Hayase, Sogo Shirota, Yuko Chiba Which group will Guest join? Once you've decided, the school exploration begins!
