A world whose music has been stolen away…
Seeking his younger brother, who was kidnapped five years ago, Ziggy meets Z.E.R.O., a robot deserter from the Mechanical Militia.
Together with Z.E.R.O. and the Superstars who control sound, Ziggy sets out to save his younger brother from the Mechanical Militia and to restore freedom and music to the world – so begins the tale of a new Song Summoner, Ziggy.

Song Summoner is an RPG in which, as the name suggests, you'll summon up music to do battle. You can create "Tune Troopers" from the songs in your iPod library and have them fight alongside Ziggy and Z.E.R.O.

There are roughly 80 types of fighters that can be summoned depending on the song title, artist and genre. Abilities and rank vary by song, and you may occasionally create a rare fighter.
Song Summoner is a traditional RPG that mixes your own music into an epic story.
