Tenkū Senki Shurato: Sōsei e no Antō

Lakshu senses a strange and expanding sohma in the human world. She is sure that it isn't the dark sohma of the forces of Azra, but is unable to identify what exactly it is. To prevent what could be a threat to our world, Lakshu sends the divine guardians of the Heavenly Sphere to investigate the strange occurrence.
