1000 years ago, he was once nothing but a red gemstone which is a source of power for not only Twinkle Kingdom but also for the entire universe and is controlled by Queen Rika (who was the ruler of the Twinkle Kingdom and the universe at that time). The gemstone contained an immense amount of energy which drained very slowly in small amounts year by year and due to that, the gemstone is slowly turning from red to black. One day, Queen Rika sensed that the gemstone is about to break so when she went to the room where the gemstone was present, she tried to do something about it but it completely shattered and because of that, the entire Twinkle kingdom started shaking like an earthquake and Twinkle Kingdom as well the entire universe is in a verge of destruction. Not just that happening but since the gem is completely shattered, the parts of the gems slowly began to reform and briefly transformed into Akuma's doll form and then transformed into Akuma's monster form and attempted to control the entire galaxy with his immense. No choice, Queen Rika uses her magic to create another galaxy named Red Galaxy (which also contains limited amount of energy for years to seal Akuma inside) and sealed Akuma to prevent further destruction of the universe and the Twinkle Kingdom and connected the Red Galaxy and Akuma with her magic so that if Akuma dies, the Red Galaxy gets destroyed because it's no longer useful if he dies.
1000 years later, Queen Sara (who is the current ruler of the kingdom and the universe) along with Angel Stella and the others lived peacefully until something happened. The Red Galaxy lost its power to keep Akuma sealed inside and so it started to tremble violently and this was informed by one of the people in the Twinkle Kingdom to Queen Sara and Angel Stella. Finally, it stopped trembling when Akuma started emerging out of the Red Galaxy but turned invisible so that he can secretly control Queen Sara which he did after that. This caused Queen Sara to become possessed by him and turned everyone into monsters called Nikushimis except for Angel Stella (who took the three stars collected by Queen Sara from the space before she could turn them evil that later turned into humans that became Shining Galaxy Precures).
Series story coming soon.
