Though I was supposed to have died in a fire, I awoke to find myself in a white room.

And somehow, I had been reincarnated as a mysterious spherical creature.

What?! What is this?! I think, but I have bigger problems. Other spherical creatures are attacking!

What do I do, what can I do—?

This is the story of a boy who died "unfortunate" and now strives for "happiness."

With the power of the Unique Skill [Ruler of Smoke] and the [Dragonkin] race, his goal is to become the strongest! Rise to the top in this otherworld!

—This time, I *will* be happy!
