Aliens walk among us—but they’re just two bros, hanging out in Tokyo. Oh, and they’re on a mission to colonize Earth.

Fuyunosuke Tanaka is a perfectly ordinary college student, except for one thing—he’s secretly an alien. He and his brother Natsutaro have traveled across the galaxy to study the people of Earth and evaluate the planet’s resources, but adapting to life on this new world may prover a bit harder than they thought.

After a series of unfortunate mishaps, Fuyunosuke and Natsutaro are on the brink of being discovered. Now the two need to learn how to act as human as possible, and fast! Thankfully, Fuyunosuke has a plan. He’s going to teach his bro how to hold down a normal job and go on a normal date. But the clock is ticking. If he fails, their entire plan for Earth colonization could go up in smoke!
