Originally created in 2007 by Nitro+, to be the mascot character of their yearly music festival, Nitro Super Sonic. However, she gained such popularity that she is now considered to be the face of the company as a whole rather than for just the festival. An energetic, clumsy, determined busybody; Sonico is an idol, member of a band with her friends, gravure model and college student (majoring in marine biology) with a burning passion for music. Does main guitar and vocals.
Heterosexual Life-Partners: With her friends, Suzu, Fuuri and Pochaco. Later in Communication With Sonico, you could also consider her to be this with her rival in the gravure model industry, Angie.
Hidden Depths: Most people consider her a blank state like most mascot characters, but Communication With Sonico demonstrated that she has a personality, dreams and aspirations. Also, most people would consider her favorite music genre to be light, bubbly pop. It's punk rock.
Never Bareheaded: Her headphones. She’s always wearing them, even in the bath. It's prohibited to bring up the topic in front of Sonico, according to Suzu. In Communication With Sonico, you can ask her about them at several parts of the game, with her reaction being that of confusion. If you continuously ask her about them, well…
Shrinking Violet: She had shades of this when she was younger, and found it hard to talk to other people. However, by the time the show starts, while she still has some occasional trouble, she's a little more assertive nowadays.
Special skills: Pro wrestling (drop kicks, specifically)
Favorite food: Melons
A young woman who has been working at the live house Supernova for a while, and also the leader of First Astronomical Velocity. Suzu enjoys teasing others and is quite witty and manipulative; but while she may seem unreliable, she can be extremely serious when the situation calls for it, and she's an extraordinary leader. Quick to anger and quick to cool down, she's the main bassist and provides backing vocals.
Expressive Hair: Her hair isn't naturally straight; she learned to straighten it when she trained to be an unlicensed hair stylist. Get her too angry or too stressed out though, and her hair will go back to how it is originally; messy, and kind of bushy. She inherited it from her father.
Fangirl: Of Rokuro-sama, an adult video actor, who seems to be a parody of Goro Tameike, a well known parody AV performer.
Fortune Teller: Apparently also worked as this for a while, one of the many odd jobs she did to rebel against her father.
Gamer Girl: To cheer Fuuri up after she saved her from the yakuza, she took her to the arcade.
Overprotective Dad: Her father is this to both her and her little sister. He became like this after a certain incident…
Missing Mom: Her whereabouts remained unknown to the Fujimi sisters for a long time. It is revealed in Axanael that she did, in fact, run away from home. The reason being that she felt neglected by her policeman husband.
A girl of mysterious origins with an insatiable appetite in charge of playing the drums. Fuuri is kind to a fault, a bit of a crybaby, and has the tendency to stick her nose where it doesn’t belong. Friendly, easygoing and the mood setter of the band, Fuuri was recruited into F.A.V by Suzu, after she saved her from the local yakuza with one of her trademark dropkicks. While she may seem like a simple girl, she hides many secrets under her calm exterior.
Dark and Troubled Past: A tanuki who came to the human world to find her childhood friend and first love, Kanta. She joined F.A.V with the plan that, if she became famous, he would hear about her and look for her. She finds out he's been dead for a while after a year of searching and a total of ten years of wanting to see him.
Does Not Like Konnyaku: It's actually a tanuki thing. Tanuki-jiru, a miso soup dish, uses konnyaku as a replacement for tanuki meat. She says eating konnyaku is like eating a comrade.
Genius Ditz: Never got any sort of training on percussion instruments before joining the band. She's always been good at hitting things, apparently.
Her Heart Will Go On: Her fate in the true ending of Axanael. She sees Kanta again, but he didn't revive. Instead of going back to her home village, she decided to stay in the world of humans with her friends, and to play the drums for his sake, and for the sake of their fans, in hopes of someday touching people's hearts.
Berserk Button: Attempting to make use of Sonico in a sexual manner (overly-risque bathing suit, being fondled by a tentacle kaijin).
Never Live It Down: In-universe example. In episode 3, Kitamura, while drunk, arranges for Sonico to make a guest appearance in a tv show. He ends up accidentally upstaging the heroes of the show, and the director throws in his unscripted rescue. He's later offered a role in the show, which he understandably turns down.
Overshadowed by Awesome: Kitamura accidentally upstages the heroes of the tv show Sonico was guest starring in during episode 3. They hilariously keep his action in the show, crediting him as a guest hero.
Reasonable Authority Figure: Despite the scary mask he wears all the time, he does try to look out for Sonico, and attempts to prevent unscrupulous people from taking advantage of her.
Spotlight-Stealing Squad: In episode 3, when he "saves" Sonico from a squid monster instead of letting the heroes of the show do it. The director of the show liked it enough and decided to Throw It In as a result.
Unusually Uninteresting Sight: His Hannya mask and 'flaming' hair. Gets averted in episode 11, when he's watching over Sonico at the shopping district. Several tourists spot him, surround him, and take lots of pictures due to his unusual mask and hair.
