Reborn As A Phoenix: A Normal Bird Can’t Beat A Dragon, Right?

Briefly about Reborn As A Phoenix: A Normal Bird Can't Beat A Dragon, Right? manga:

Then one day, after a near death experience, he felt both fear and powerlessness. He wanted to fly freely without the limits of Earth's gravity controlling him. He wanted to strike his wings like a dragon... Or maybe a phoenix! He finally got his wish in the form of an "un-normal" bird, but still felt that something was missing.... Something only attainable on earth... A dream perhaps?
