Ichika Orimura (Seiyuu: Megumi Ogata)
15 years, 162 cm, 53 kg
While she appears polite, silent and submissive most of the time, she was a tomboyish and cheerful girl when befriended. Her inferiority complex toward her almighty sister was probably contributes to such outer demeanor. She’s a very dedicated when it comes to helping her friends, especially those in distress. Due to her masculinity and ingenuity in her excited state, she gained considerable fan girls following (and sometimes, worship) her, which she dismissed as extension of her sister’s charm.
Her performance as I.S. pilot is at best fluctuating; heavily depends on her willingness to do her job. Average, she has enough performance to be considered a Cadet Representative for Japan, where she must compete with fellow cadet Kanzashi Sarashiki. She was kidnapped three years prior and joined the same protection program as her childhood friend Houki does. While not as skilled as Houki, she was an accomplished kendo athlete.

On a first glance, he seems like a laid back person. However, he’s a hard working and very dedicated boy. He’s also very modest, often prone to self depreciation and is bothered by expectation put on him. Kind hearted and handsome, he’s a natural Casanova. Possibly in denial, he’s very oblivious about such attraction to the point of accidental stupidity. He also romantically dense submissive, especially to his friends (which caused him to be abuse victim all the time)
As I.S. pilot he's extremely talented, however experience wise, he's still inferior to his friends, who is composed of Cadet Reps. Eschewing planning and prefer improvising, that's why sometimes he won against massively more powerful foe, and yet defeated soundly by other foe that's not much superior.
Master Sergeant Otoha Sakurano (Seiyuu: Ayako Kawasumi)
16 years, 159 cm, 49 kg
Naïve, cheerful and upbeat, Otoha was born and raised in a small island cluster near Hokkaido. Due to the lack of experience, she didn’t know a lot about the Japan mainland, and while exaggerated, her reaction upon arrival is expected. She is extremely conscious about her body and had comical sense of inferiority about it.
She always dreamed to be a pilot someday, and her recruitment by JDSF practically a huge stepping stones to achieve that. Being an amateur and somewhat underachiever when it comes to theoretical learning, she started out rough, but otherwise promising recruit and frequently pulling a surprise performance that astonished both her superior and fellow pilots. Excellent with Kendo.
Sakurano Yuuki (Seiyuu: Miyuki Sawashiro)
16 Years, ??? cm, ?? kg
Mysterious boy that tend to appear and disappear without notice, often mistaken for a ghost because he's virtually untraceable. He's revealed to be Otoha's missing Brother, and that incident is the beginning of WORM's resurgence. Even though he appears kind and non hostile, he also kept silent and made everyone's careful, especially since Yuuki is also capable of shapeshifting and made clear he's related with WORMs. He's also personally knew Tabane Shinonono, which doesn't help everyone's trust issues.
He also is capable of doing borderline superhuman feat (such as running along cars and jumping between buildings), and is more than capable of fighting a cadet rep toe to toe. Later, he also assimilated the damaged golem's frame for his own use.
