Houkagogakari

ほうかごがかり

Kei Nimori, a sixth grader, finds his name scrawled on the classroom blackboard one day, alongside the mysterious word "Houkagogakari." That night, at the stroke of midnight, he hears the sound of school bells and a portal opens in his room, revealing his school transformed into a dark, otherworldly dimension called the "Houkago."

In this twisted version of his school, monstrous beings known as "anonymous wonders" lurk in the classrooms. Six boys and girls are summoned to the Houkago, tasked with observing and recording the nature of these monsters. Kei, who is skilled at drawing, must use his brush to capture "Makkaka-san," a monster hiding on the rooftop. There are no correct answers, no clear goals, and no way to escape—only the risk of death piling up as they try to suppress the creatures.
