Template:Cloud Abilities Needle Sphere Form (球針態, Tama hari tai) is a technique used by Hibari's Cloud Hedgehog Box Weapon, Roll. After being injected with strong Flames, Roll can form an airtight sphere around a target to trap them. It is made from compounded Cloud Flames and the inside of the sphere has the ultimate power of isolation. The sphere can only be broken by strong Flames such as Tsuna's Hard Sky Flames. Because it is an airtight sphere, the oxygen inside is limited; if the person inside doesn't escape quickly, they will suffocate and die.
