|Hand Seals||Hare → Dog → Ox → Snake|
This technique allows the user to create a senbon-shaped icicle in their mouth before spitting it out at a high velocity. The ice-senbon are stronger durability than ordinary senbons. Due to the durability of the icy needle, the target may be pierced.
The user may craft a single ice-senbon in their mouth without any use of hand seals. However, for the user to create additional senbons, hand seals are required. This means the user can either fire a single senbon or by using hand seals, fire a stream of senbons at a target. These senbons can be used as a distraction or as a surprise attack.
