“What on earth is that Bomber!?” Gates to another world have been developed, and various countries are building special zones in pursuit of new resources. Each is exploring and developing a different otherworld, named the New World. Since there is a possibility of being affected by unknown viruses when humans go directly to the other world, each country has been sending in specialized remote-controlled robot called “Actanoids.” Chihaya Usabuki, who had failed to find employment due to her timidity and communication disorders, is attracted to the words “full-time remote work” and becomes an Actanoid operator, an “Actor.” That choice was the moment that gave birth to the Bomber, which would send shivers down the spines of those involved in the New World.
