Everyone in the neighborhood knows that the Natsume family has a pair of very strange twins.
The younger twin, Suguru, excels in both his studies and social life, and has always been the model child everyone else's parents wish they had. Aside from his unnerving habit of staring into empty spaces when he was little, he has no other flaws. But for some reason, this promising child suddenly transferred to a religious school.
As for the other twin, he's been strange ever since childhood. He neither laughs nor cries, and he seems to appear and disappear at will. People say he can often be found at crime scenes and haunted places.
"Help! I dreamed my little brother was going to kill the whole family. Then I realized he might actually be planning to kill the whole family. What do I do?!"
"Help! I've always suspected my big brother isn't human. Then I realized he might actually not be human. What do I do?!"
An ordinary person's desperate struggle to survive in the JJK setting.
Twins, no romantic pairing.
The protagonist has no cursed energy and is a non-sorcerer. He can fight, but he is not Heavenly Restricted.
