DESCRIPTION
They spend most of their time inside the host, but when they grow to a certain extent, they escape from the uterus, sucking nutrients from the host's body, and are protected. This time is a short time, but it greatly affects the host's body and makes changes not only in the uterus but also in other parts of the nervous system. As a result, even when the octopus' growth is over, the host's body welcomes the host to become part of the swarm before the mind responds.
