I wrote this song based on the image of LOL’s Mordecaiser.

Edge of the night (Alter Ego version)

It’s a song I made in the early days. It was also around this time that it became a little more metal-like. I use Marie Orc of AlterEgo on vocals.

Pull Request From Abyss

It’s a metal mixed with chiptune. It’s pretty gritty. This is a new song I made for distribution.


It’s a song with vocaloid Chris. The lyrics can be found here.

Legacy Systems

It’s an acoustic song. It’s a quiet song with a piano, acoustic guitar and drum structure.

Messiah(Acoustic version)

This is an acoustic version of a metal song from the second album “Territory Of Flying keyboard”.


It’s an alternative (?) song composed of piano, electric guitar, synths and drums. It’s a rock song like metal that can’t be said. It’s not too shabby.
