Rielle Corallia

Rielle Corallia is a student at Royal Sword Academy, a sophomore, and the housewarden of Marinafinne dorm. He is the seventh prince of the Coral Sea, having left his home to come to the surface that he longed for against everyone's objections, even if he charged headfirst recklessly. Rielle is a beige-skinned young man of average height with long, wavy red hair that goes past his waist and deep turquoise eyes. For his dorm uniform, he styles one section of his hair at the back into a messy bun that is held together with a fork. His bangs fall from the left and parts into the shape of a starfish that doesn't cover his face. He decorates a strand of hair that goes from the front to the bun with two small, gold, marine-themed hair cuffs on both sides of his scalp. His eyebrows are the same color as his hair, and he has minimal makeup on the rest of his face except for his eyes, where teal eyeliner lines the ends of his upper lashes. His cheeks have a light pink blush on them. He is 170 cm/5'7".

His dorm uniform is mostly made up of multiple layers of styled tops and accessories on his waist. He wears a green outer jacket with light pink underlining and cuffs. The edges of the lapel are lined with two gold strips, and on the left is a pin of his dorm's emblem fixed onto it with a seashell charm hanging from it. His jacket is open and has buttons for decorations, gold and placed on the body's front area on both sides. On the placket of both sides is one buttonhole relative to the position of the upper buttons. The top of his cuffs are lined with gold embroidery that goes up to his elbows in the form of a patch. Underneath his jacket is a long, light teal button-up shirt that flows to the back of his knees, likely with a white scallop pattern, which is not visible on the top. From the waist down, the pattern is more pronounced, and the placket is trimmed to the bottom-back in waves. Over the shirt is a plain lavender vest with the same buttons on his jacket but smaller.

Everything under the jacket is decorated with brown belts on top of them, styled messily to resemble an adventurous look. Seashell charms hang from them; one hanging from the middle belt is a charm of Sebastian, and another from the bottom one, around his waist, is a charm of Flounder. Some chains on the belts also hold utensils, tools, a pocket watch, and other items.

Rielle wears pants of the same green shade as his jacket, and the hems are tucked under his boots. His shoes are dark blue button boots that reach his mid-calves. On the front of each boot are pairs of gold buttons secured together by a string of gold lace per pair.

Rielle is enthusiastic and energetic when he first appears, optimistic about everything he sees around him. His optimism comes from being on land and experiencing things he never had underwater, and his longing to leave the ocean seems to have started while he was still underwater. This is further proven by the way he left unannounced and recklessly, with one goal on his mind. He is also adventurous and open to trying new things, even if they don't seem practical or timely. When he met Azul again, he was quick to interact without much thought with him, even to Azul's surprise. While he appears to be oblivious, he isn't and realizes how his words can affect others, as well as his own limits and what he reasonably wants.

Rielle was born the seventh prince of the Coral Sea's royal family. He attended the same elementary and middle school as Azul, Jade, and Floyd and went on a school trip to the Atlantica Memorial Museum when he was 7 with them, where a commemorative photo of them was taken, titled "A visit from Prince Rielle and his schoolmates..." He remembers Azul when they meet again during the interscholastic Relic Labyrinth tournament in Book 8, even with differences in their appearances.

Rielle received an admission letter to Royal Sword Academy two years before and left the palace and ocean unannounced, causing panic below. He wasn't as heavily dressed or "vivid" when he was underwater, likely due to color distortion, and coming on land to see his real self was one of the things that he was optimistic about. When he arrived on land, he was unaware that his previous peers did too and trained at a different organization to adapt to land, where they couldn't contact him either. His motive to come on land appears to be due to his enthusiasm for it as well as to prove to his father he isn't a child anymore.
