Super Dimension Fortress Macross: Eternal Flash

I transmigrated, then discovered I was Gilgamesh... Well, I haven't had the chance to get smug yet.

The Birdman uses an area attack!

You mongrels! Behold my Gate of Babylon!

That's just wishful thinking. Actually, it's a story about a Gilgamesh-template character going from abnormal to normal.

The plot follows the Birdman, the original series, a little Frontier plot, and a whole lot of Macross Delta plot...
