Suko

Under Goū's robes on the back of his waist lays this weapon. How is something so big concealed in such a small area? Simple, it expands into a pole or goes back into itself to stay hidden where it belongs. This weapon secretly has a chain mechanism inside it, allowing either to extend for a small distance. This blade also has the ability to drain an opponent's chakra with each strike, transferring into the wielder of the weapon.
