Astral Arts

This Core skill set is based on augmentation of the user's natural abilities to enormous levels, allowing one to fight on par with Shinpi-level individuals. Astral Arts are learned and improved through the fostering of the thin link between the spirit and "outer" space (another plane of existence that is only vaguely alluded to in the series). So far, only Genruu Modoru has been referred to as having the potential to access this Core.
