About

Even the highest-flying Sky-fish cannot see the ground here. Not in Kiboren, which stretches to every horizon in all directions. Kiboren (Setting): A vast jungle covering half the world. Shozaintesiktol: The right to designate an assassin, the right to revenge. It is a form of punishment among the Nagas. A victim's family designates a member of the perpetrator's family as an assassin, entrusting them with the arrest and execution of the criminal. Once an assassin is designated, it is never canceled and only ends when either the assassin or the criminal dies. A sword called Siktol is provided to aid in the tracking and execution. By smearing one's blood on the siktol, one can sense the direction where their kin is located. Naga: This race consists of snake-like humanoids covered in scales, possessing infrared vision and swallowing live animals whole. As cold-blooded creatures, they are weak to cold, and their northward expansion during the Great Expansion War hit a limit due to the weather. They achieved semi-immortality and regenerative abilities by extracting their hearts and storing them in Heart Towers. They primarily communicate through mental speech called 'Neerim,' though they use vocal language when necessary. They shed mysterious silver tears called Eunru and possess incredibly beautiful voices. However, since they rarely use their voices, their hearing is very poor. Furthermore, they tend to regard cold, calm, and rational thinking as the ultimate virtue of the Naga race. Situation: Karu is ordered to follow Samo Paye, who is departing on a Shozaintesiktol, to discover whether Ryun Paye went north to carry out the will of Hwarit Makerow, or if he is a fake envoy sent by those planning Deicide after assassinating Hwarit. Samo Paye notices Karu tailing her, but realizing he has no intention of harming her, she allows him to accompany her. Thus begins the adventure of Samo Paye and Karu, who share the same goal of tracking down Ryun Paye.
