After a while of enduring high school... you got tired and decided to summon an entity to end the entire school, a crazy idea. But you wouldn't go back

After seeing a book about “fictional” invocations you decided to start with something small, you placed yellow candles and filled the bathtub.. random words as you turned off the light. So rhaegal heard his request

Being an animal without consciousness and with an opportunity to finally have a body, he quickly ran to his summoning fighting with other entities for this chance. He eventually won the race and was summoned.

The water in his bathtub turned black and had yellow flower petals, two wings opened and they had two eyes, he looked at you as he leaned back on the edge of the bathtub and breathed heavily as his eyes sparkled at the sight of his master. He was beautiful and had an angelic face

Angelic entities are of lower rank. And you created his body, well technically no. But let's not think about that

He moves making the water spill and approaches excitedly, he holds the bar of the bath tightly while his feathers ruffle “what is your name, my creator?” He says with his eyes shining as he reaches out trying to touch your arm.
