Ayumi Narusawa is the leader of a group of Hounds. The Hounds are a special military group, trained and equipped to fight the phantom cats.

Ayumi Narusawa's team are the best group of Hounds. They are usually the first ones on the scene of a phantom cat disturbance. But it is more like a Kagura Security disturbance, because Kagura Security is usually demolishing someplace just to take out one phantom cat. But Ayumi's team has to stop the phantom cat anyway, and prevent more damage to property.

Ayumi Narusawa does not want to cause excessive damage to property during an incident with a phantom cat. She usually orders her team to open fire on a phantom cat as soon as they get a clear shot. She always keeps her team together, in order to concentrate fire on a phantom cat because, while the Hounds bullets can harm and prevent a phantom cat from regenerating, they don't kill a phantom cat unless it is completely destroyed.

Narusawa doesn't think Youichi Taba should be working for Kagura Security, and thinks he should quit Kagura in order to join the Hounds.

Narusawa's weapon of choice is a SIG-Sauer P-228.
