Nature Spirit: Space

Nature Spirit: Space (精羅：宇宙) is a SIGNI class associated with white SIGNI, first seen in WXD-09 White Pray. They are all titled "Natural Star" and the majority of them are named after the most famous or brightest stars of a constellation, while their Resona are named after planets in the Milky Way galaxy. As such, they are led by Milky Way, Natural Star Princess.

Although named after the stars, Space SIGNI are designed bearing the image of the constellation of which they belong to, such as scorpions or centaurs. In addition, they often hold something to indicate their namesake star's stellar classification or star system, such as having large red orbs or multiple spheres around them. In the same vein, Space Resona are designed with the most striking features of their namesake planets, while also holding motifs of the Roman gods the planets are named after.

Gameplay
Space SIGNI are the first to introduce the Resona mechanic. As such, many of their effects focus on gathering each other to meet the needs of the Resona's Play Condition. Some also gain power when 3 of them are present on the field, making them sturdier for later playing a Resona.

Space Resona focus on restricting and controlling the opponent's field conditions, through abilities such as reducing the opponent's limit, causing all of the opponent's SIGNI to lose their abilities, or outright restricting the amount of SIGNI they may play.
