Koishi Komeiji
aka Dolphin Rider Koishi

Personality - Initially very nervous and cowardly, but grows more confident throughout the story. Well meaning but can’t resist a good quip now and again (only playfully, though). Tries her best to see the good in everyone. Is getting into the magical girl act more than she’d like to admit.

Normal outfit - school uniform, a relatively realistic seifuku (see http://i.imgur.com/ChB5c.jpg). Silver hair, dark green eyes. In her ‘human’ form, her third eye is absent. Flat-chested.

Siren outfit - white one-piece swimsuit with an orange teardrop in the centre. White elbow-length gloves with dolphin emblems on the back of the hand. Long ribbon around her neck, same colour as the Teardrop. Her third eye is back, and closed as usual. She wields a mighty-looking golden trident (imagine King Triton from The Little Mermaid). Optionally, a golden ring on her right hand (Ring of Breath, allows for underwater combat).

Mokou Fujiwara
aka Fujiyama Phoenix

Personality - Highly energetic health nut with a habit of giving tips to people who don’t particularly want them. Seemingly endless stamina. Has had a bit of a rebellious streak, but she’s trying to work her way out of it. Likes the adrenaline rush from combat and tends to be a bit reckless in a fight.

Normal outfit - likewise, see http://i.imgur.com/ChB5c.jpg. Alternately her idea of casual wear is a white shirt with pale red suspenders. Long black hair with a single ribbon, brown eyes with a hint of red. Noticable chest, but not large by any definition.

Siren outfit - Hair is now silver, and her eyes are now very much red. Red tank-top with a golden phoenix emblem. Shorts that are clearly burnt along the bottom, coming to a stop about halfway up Mokou’s thigh. Gritty combat boots, more ribbons in her hair (like canon Mokou). Armband near the top of one arm with an phoenix feather clipped to it. Two red fingerless gloves with diamond-shaped jewels built into the knuckles (typically blue or white).

Sakuya Izayoi
aka Mysterious Jack

Personality - The least heroic of the Sirens, with a definite streak of ruthlessness. An invaluable ally but a terrifying enemy. Cunning and agile, but rather weak physically. A definite trickster who takes pleasure from fooling her opponents and proving her own superiority. Is much more aggressive in her mockery than Koishi’s playful jibes.
Ultimately, though, she does have a grasp of justice and will do the right thing unless a personal vendetta distracts her.

Normal outfit - Long-sleeved black jumper, long grey skirt. White thigh-highs and formal black shoes. Hair is like canon Sakuya, but has been dyed blonde. Blue eyes. Flat.

Siren outfit - Hair is back to silver. Eyes are blue, but flash red during time-stops. Wears a white shirt with a black vest on top of it (and her dark blue Teardrop on top of that). Long black pants, formal black shoes. She’s wearing a fedora, and there’s a deck of cards in her vest pocket. A silver pocketwatch hangs around her neck by a chain.

Komachi Onozuka
aka The Red Lily

Personality - Outwardly very laid-back and laissez-faire, but is secretly much more mature and pessimistic than she lets on. Has a strong sense of justice that has matured over years of seeing the worst Gensouto has to offer. When she needs to be serious, she starts acting like the lawyer she’s supposed to be, but when she can afford it she’ll play around.
(Secretly a massive fan of Wild West films in general.)

Normal outfit - Brown pigtails and pale red eyes. Dark blue business suit with some ruffles and creases. Shiny prosecutor’s badge (similar to the Phoenix Wright badge) on her lapel. Formal black shoes like Sakuya. Breasts = Very Yes.

Siren outfit - Canon red hair/eyes. Black overcoat, with a white button-up sleeveless shirt underneath. Worn denim jeans and cowboy boots. Wears a belt full of pouches with a coin emblem in its centre. Wields her trademark gun, the Titanic, in one hand. (The Titanic is essentially a massive revolver, along the lines of shotgun proportions. Imagine a Gunblade from FFVIII minus the sharp part.)
