Because Ramiris has been reincarnated and has not grown up yet.

Ramirise is a demon king who has repeatedly reincarnated and grown. Because she has inherited the self and memories of her previous life, she is the only demon king allowed to be hereditary. The original Ramiris had a very majestic appearance. She was supposed to be a great beauty. She also had the strength of a demon king and would be reincarnated into the next generation after her death. Although the current little Ramiris has inherited her self and memory, her strength can be said to be very weak before she grows up.

Experience

The creator of this world, Star King Dragon, fell in love with humans and gave birth to a child. This child is now Milim. Incredibly, after falling in love with a human, Star King Dragon lost all his power and became no different from an ordinary person. Since he was restricted by his lifespan, in order that his beloved daughter would not be alone in the future, Star King Dragon entrusted Milim with the care of an Elf Dragon similar to his own reincarnation.

Mirim soon became friends with the elf dragon, but the good times did not last long. For unknown reasons, a certain human kingdom set a trap and killed the elf dragon. The Fools touched the tyrant's reverse scale, and Milim, who had lost her parents at that time, went completely crazy because of this incident. The world-destroying rage destroyed the country and made Milim awaken as the Demon King. Enraged, Milim irrationally destroyed all humans in sight. Be it cities or countries, humanity is on the verge of extinction.

At this time, Demon King Guy, who is the "mediator" of the world, came to stop the rampaging girl due to an agreement with his best friend Star King Dragon to avoid the extinction of mankind. The battle between the two was evenly matched and earth-shattering. They fought for a long time but could not decide the winner. If they are allowed to continue fighting, there is no doubt that the world will be destroyed. At this time, someone stood up, and that was Ramiris, the queen of the elves.

As a weight to balance the world, she stepped into their battle without hesitation. There is no doubt that the Elf Queen is powerful. As the guide of the "Saint", Ramiris has huge strength that is not inferior to the two demon kings. Because of Ramiris' intervention, the battle became one-sided. Finally they succeeded in waking up the crazy Milim. This world crisis ends here.

But the price is also huge. As a "holy" queen, she lost her resistance to the "demon" because she exerted all her strength in the battle. After losing her resistance and being exposed to an environment with extremely high concentrations of magic, she was quickly infected by the magic. Unable to retain her pure Saint, she degenerated from an elf into a goblin. This forced her to reincarnate repeatedly in order to maintain herself and improve her strength.
