MEOW KOKORO MEOW! (ASTRA X ALIEN MAGMA FANFIC)

(Note: Ultraman belongs to Eiji Tsuburaya. I just wrote this for the fun of it).
L77 is devastated by the Alien Magma during the Magleo War. They have culled almost all the L77 Ultras, brutally slaughtered the royal family and kidnapped and tortured their only surviving prince, Astra. Chained and forced to endure it, Astra desperately clings on to whatever is left of his sanity, hoping he can escape.
And one day, his prayers are answered by someone unlikely.
After being freed by an Alien Magma queen, Astra starts to see a new side of things he had never given much thought of before, including his sworn enemies. Astra knows that he must trust her if he wants to reclaim his home planet, as well as choose the kind of life he really wants to lead.
Will he succeed?
And what kind of secrets is Chhaya, the so-called 'shadow assassin' of the Alien Magma, hiding?
