Rostach Pocketknife

Since Kingu was the de facto Boy King of Rostach before he was adopted by Marduk. He might look scrawny and weak, but he actually possesses alarmingly explosive power. He can even put down someone two heads taller than him the moment they let their guard down. Not exactly well-read, he has a surprisingly active mind. Even when surrounded by ruffian kids looking to pick a fight, he would always come up with some ingenious way to hit his opponents hard. If such kids let go of their beef with Kingu and started taking his orders instead, Kingu would become an outstanding leader to them, leading them to steal bread and fight hooligans with the wind at their backs. Boy King Kingu's most notable fight, however, also got him into the biggest trouble—he successfully led a group of street kids to steal a cargo truck from the Akkadian Guild. And not even an hour later, the orphanage was surrounded by bounty hunters. The trembling director had no choice but to hand over the chief culprit, Kingu. That was Kingu's first encounter with Marduk, his adoptive father. Defying all expectations, Marduk's eyes were brimming with approval—Not only did he donate all the stolen goods to the orphanage, he declared that he would adopt Kingu.

The only "possession" the young Kingu brought with him out of the ruins. In principle, it works similarly to a chainsaw by dealing damage to enemy flesh and armor with its rapidly rotating saw teeth. In a fight, the user can hit a switch located at the hilt to activate the fuel motor to make the saw teeth rotate at high speed.
