Wakana Rei is a second-year high school student at Geijutsu Academy's Musical Department. She goes by the stage name LAYER (レイヤ) and is the vocalist and bassist for the band RAISE A SUILEN.
She is Tae's childhood friend.
Rei has fair skin and smooth dark-brown hair reaching her top back with no fringe, but bangs that cover her ears and lightning blue eyes.
Her outfit consists of a white shirt with a wide neckline and long sleeves to her wrists, slightly torn jeans, and a black sleeveless jacket open until mid-torso.
She carries a studded belt with chains made of silver on her right hip, a leather bracelet on her right wrist, and a black bracelet on her left wrist. She also wears two necklaces, and her shoes are high ankle boots with black shoelaces.
Rei is a calm and mature girl. Due to her mature attitude, she has a tendency to keep a certain amount of distance from others (for example, not giving her opinions, or hiding her troubles from others, as shown in the event outside/inside where she overworked herself in order to perfectly play the hard bass parts she was given during her and Masuki's gig). She is also sometimes mistaken for an adult due to her mature appearance; in an area conversation, she says the movie theater workers couldn't believe she's a high school student.
She is a professional singer who can sing any song, and has loved singing ever since she was young. She has a very deep voice for a teenager. As a child, she even mentions that she was too shy to sing because she "doesn't sound like a kid", before Tae started interacting with her and she was able to overcome her complex.
