This is the opening theme song of Gatekeepers, a very good animé that was made several years ago but is still making an impact to myself.

For those who have not watched it yet, this is the story of the Earth, being invaded by, uhmm..”Invaders” and it is up to a certain-certain called A.E.G.I.S. which will protect the Earth from them.

I am telling you that you should watch this Animé, okay?

That is it for now. :)
