"Field report on Indigenous conflict and supernatural phenomena:

The indigenous legend of Shinigami Knights, in which living people as sacrifices to summon ghosts from the underworld, and the ghosts will destroy the enemies of the sacrifices as agreed. There is growing evidence that this is not just a legend. Thanks to the hard work of our intelligence department, we are learning more about these amazing phenomena. Earlier records about the tribe's customs of human sacrifice are not accurate. These sacrifices are not just worship of the so-called underground gods but have direct practical functions. We can be sure that sacrifice is a prerequisite for summoning Shinigami Knights. In using drones to record a large number of tribal conflicts, we have observed some "supernatural" phenomena, including the distortion of the earth's surface and the disappearance of human bodies out of thin air. The biggest discovery is the multiple captures of the legendary Shinigami Knights.

The sacrificer will disappear after the surrounding space is distorted, and then a Knight will appear in the original position of the sacrificer. These Knights use different melee weapons in the battles and have strong combat effectiveness. They cause a large number of casualties to the enemy every time they appear. In tribal-level conflicts, they can usually turn the tide of the battle. Further observation revealed that the Knights were not supernatural ghosts, but rather biological machines using modified military-grade prosthetics from the old civilization. More specifically, They are using the Oni-class cyborg body, which is the same type we've discovered and used on Sadashi and Kayako. The difference is that the improvements on Knights make these already extremely dangerous prosthetics more powerful. These improvements exceed the technical capabilities of any current kingdoms and colonies. This proves that some people or groups have mastered more old civilization technologies than we do. Let me even make a bolder hypothesis. The so-called underground gods are the remnants of the old civilization itself. . Whether or not this hypothesis is true, these Knights will be the key clue to our discovery of the ultimate technology of the glory days of mankind. Please do consider allocating more resources and manpower to the project on capturing these specimen. I have attached project details with this report."
