Jakutian Ways...

the planet of Jakuta is a planet far away from our own, though it is quite similar, except for a few factors that make it different.
The entire planet is dark.
There is no light on this planet whatsoever. There is no natural light
and no artificial light. It is always night time. Even the planet's atmosphere blocks out natural light from the sun and stars.
How would something with no light survive? The planet's atmosphere has adapted to block out the cold from space, making the entire planet pleasantly warm. Animals do indeed roam here, though they are all blind, as well as the people. 
Trees, flowers, and other plants are all colorless. The people and animals don't rely on sight. They rely on scent, sounds, and touch.
The strange thing is, the people all have eyes.
Why have eyes if you can't use them? What purpose would they serve in evolution?
That is what Hisoki was going to find out.
He just needed a little bit of help...
