Japanese Title: "Koe"
Asami: As social animals, humans affect each other in many different ways...through pheromones and long range infrared rays. For example, you get along with friends who share your interests.
Keita: Yeah, I suppose.When I'm in class with Usshii, we talk about military things...and we end up getting scolded all the time.
Asami: It's the same as that. Dual Kinds are those who work in pairs to strengthen...the brain impulses to generate a special kind of energy. And neuronoids amplify that energy by tens of thousands...and operate by using the energy as motive power. There's the Accept Mode for surveying and analysis...and the Active Mode for movement and power. In order to properly bring out the best of these abilities...it's necessary to have two Dual Kinds to act as head divers.
