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 prove a bit harder than they thought.

Fuyunosuke’s been living the good life in Tokyo. In fact, he’s almost got the whole “being human” thing down. His brother Natsutaro, on the other hand, can’t figure out the first thing about blending in on this strange planet. There’s still a lot they don’t know about humans, but with any luck, Fuyunosuke might just be able to show his bro that life on this little blue ball isn’t so bad after all.
