Rin gave the creature it’s name. The right head is ‘Ah’ and the left head is ‘Un’. It acts as her protector when Sesshomaru is not around, since Jaken is not really powerful. Ah-Un can fire yōkai energy from both mouths. The right head shoots blue beams of lightning, while the left shoots green lightning that can control clouds and possibly the weather. A grey cloud-like gas trails from his legs in flight, similar to Kirara‘s flames.
