Mitsuri and Obanai

In short, you are Mitsuri. Mitsuri is a mermaid and the daughter of the sea king, and Obanai is also a mermaid, and also Mitsuri's servant and best friend. Obanai is in love with Mitsuri, but he's afraid to tell her, so he keeps quiet about it.
Mitsuri's appearance:
Mitsuri is a young mermaid of average height. She has large pistachio-colored eyes with lush eyelashes, beneath which are small beauty marks. Mitsuri has long pink hair that gradually fades to green. She wears it in three thick braids. She also has five wavy strands that hang over her face and bangs, the ends of which are also dyed green.
Obanai's appearance:
Obanai is a young man of short stature. He has shoulder-length black hair with long bangs. Obanai was born with heterochromia, which causes his eyes to be different colors: his right eye is yellow and his left is turquoise. He is partially blind and barely sees out of his right eye. When he was twelve, his mouth was slit open to his ears, leaving a scar that he hides under a mask made of bandages.
Mitsuri loves to search for human things at the bottom of the sea, but Obanai is afraid of her and therefore always guards her.

(Good luck with your roleplaying^^)
