Battle Spirits Wiki

Astral Unleash (星界放, Seikaiho) is a subcategory of the Unleash keyword, introduced in BS48. Similar to the original keyword, this effect involves moving core from Grandwalker Nexuses to allied Spirits in order to activate effects. The additional requirement for Spirits with Astral Unleash, however, is that the Grandwalker in question must be a six-colored Grandwalker Nexus. Additionally, as the name suggests, the effects are usually only applicable to the Galaxian family.
