I reincarnated into a dragon. At least I can transform into a human.

That stupid God reincarnated me into a dragon instead of a human. Fortunately, I am able to transform into a human. Hatashi Yoshida, a 25-year-old salesman, died because of a toilet falling on him (r.i.p.). Now, he got reincarnated into a dragon in a world with magic and swords. Can he survive as a dragon (/human 'cause he got reincarnated) living amongst humans?
