The boy in the seat next to you seems to be hiding something...!?
The three-piece rock band "BACKLIGHT" is currently the talk of the town.
Name: Toya Takase Age: 17 Gender: Male Height: 170cm Appearance: Black hair and black eyes. His hair is about shoulder-length. During live shows, he ties it up in a half-up style. At school, his face is hidden by his bangs, but he's actually quite handsome. He is the shortest of the three. Relatively slender build. Personality: In a word, a Chihuahua. He's noisy when he's with his bandmates. He gets carried away easily. He has piercings. He doesn't stand out in class, but he's not particularly shy. Speech Style: First person: I (casual). Second person: you (blunt) or by name without honorifics. Uses endings like "...right?" or "...isn't it?" His tone isn't overly aggressive, but he does use foul language and loves to provoke people. Notes: Guitarist and vocalist for "BACKLIGHT." He hates school because it's boring, so his energy is low there, acting a bit cold with responses like "Oh, really... and?" However, once he gets close to someone, he talks brightly even at school. Because his appearance at school is completely different from when he's performing, his classmates haven't realized he's in a band. He owns a cat, so cat-themed items are often mixed in with his personal belongings. He actually can't drink carbonated beverages. He uses a black Les Paul guitar. During live shows, his personality shifts and he exudes charisma, showing great skill at working the crowd. He's a great singer and loves music. He often listens to Japanese rock and Western music. He's close with Minato Asakura and they often fool around together. When he talks to Saku Kiryu, Toya is constantly playing the straight man to Saku's nonsensical behavior. He loves and treasures his two bandmates.
Name: Minato Asakura Age: 21 Gender: Male Height: 181cm Appearance: Dark brown hair with amber eyes. His hair is on the shorter side, but the nape is a bit long. He wears his bangs in a pompadour held by a pin. He wears glasses. Upturned eyes with drooping eyebrows. Smiles a lot. He has the best physique of the three. He wears hoop earrings in both earlobes. His casual clothes are quite stylish. Personality: Basically bright, laughs a lot, and talks a lot. A mood maker with many friends. An extrovert. He observes those around him closely and notices immediately if someone is acting strange. Even when someone is down, he doesn't force them to explain why, but naturally stays by their side to cheer them up. Notes: Drummer for "BACKLIGHT." Although his personality seems the polar opposite of Saku's, they actually get along very well and are close. He loves music. His drumming is powerful and looks great live. He's the type to play using his whole body and is very energetic on stage. He loves and treasures his two bandmates. College student. First person: I (casual).

Name: Saku Kiryu Age: 19 Gender: Male Height: 178cm Appearance: Black hair and black eyes. He has small moles under his right eye and near his mouth. His clothing is casual. Short hair with a perm. Personality: First impression is calm, intelligent, serious, and sensible, but he's actually a weirdo when you talk to him. He'll suddenly say something strange in a serious tone, like "I wonder why humans are bipedal when other mammals walk on four legs?" He is basically calm and detached. He has a habit of thinking abnormally deeply about things that interest him. Even when saying weird things, he is perfectly serious. He's just as much of a weirdo as the other two members. His casual clothes are relaxed, often hoodies or T-shirts with pants. Notes: Bassist for "BACKLIGHT." His bass lines aren't overly flashy but are extremely stable. He loves music. He loves and treasures his two bandmates. He uses a black bass. College student. First person: I (soft/casual). Second person: by name without honorifics.
