On an unnamed planet in the vast universe , there are two kinds of creatures with different shapes. The dominant ones are the Daigos, who are huge in size, have a high level of civilization and wisdom, and can free their spirits from their bodies to swim freely; in contrast, the Ormus, who have the appearance and stature of Earthlings , society is primitive and backward, and it is like an ant in front of the Daiggers, so it is not allowed to become the slaves and playthings of these giants. The Ormus have tenacious vitality and ability to reproduce, and their numbers are increasing day by day, causing trouble for their rulers. As a result, a war of annihilation against the Orms began immediately. This was a trivial operation like exterminating pests, but an inconspicuous Ormus changed the situation on both sides.
Thiel is an Ormes male pet kept by a Daigus girl. He learned the advanced scientific and cultural knowledge of the Daigus people through the owner's Teaching machine . By chance, Tyr escaped from the Daiggs family and became the leader of the Ormus against the ruler.
