Princess Mikotsu is seen with dark grayish blue hair that is put into long pigtails. A skeleton fish sits atop the right side of her head and often speaks for her, just as her sister Uomi. She wears a kimono, similar to Tatsumiya's, except it is a dark gray with a skeleton fish on the middle part with red outlining. White lace adorns the hem and part on the mid section of her kimono. Her eyes are red and she appears to have bandages wrapped around the right side of her face, covering her eye. She also has hands with no flesh, resulting in a skeleton-like look, which is the same for her arms.
She does not talk much (she can barely talk at all!). She also loves to see others suffer. Princess Mikotsu has a great hatred towards her sister Princess Uomi because the Sea God chose the latter instead of her. With great hatred towards her sister, she is heavily devoted towards her father, wanting nothing more than to receive his love.
