Cecilia Alcott is one of the main characters from the IS:Infinite Stratos anime and novels.
Cecilia is a 1st year student at the IS Academy. She is a student in Class 1 and is the IS Representative Candidate of England.
In the AWA fics, Cecilia is a student at the AWA Academy.
In the XP4 fics, Cecilia is a trainee at the Heroes Coalitions. She also attends the Vanguard Academy as a student.
Cecilia has light blue eyes and long, light blonde hair that forms drill-like curls at the ends, along with a royal blue headband that holds her hair up. She is noted to be extremely beautiful, and has large breasts and a voluptuous figure. Her IS Academy uniform is slightly modified, as it has a long skirt instead of a short one, and there are black frills at the end of the skirt and sleeves. For her IS practice and battles, she wears the blue version of their training uniform. Her IS in standby mode takes the form of ear accessories. Ichika has often compared Cecilia's beautiful face, long, slender limbs, and well-proportioned figure to those of a model; she has admitted that she has worked as one in the past. Aside from the academy uniform, Cecilia usually wears high class clothes, like dresses, as casual wear.
Cecilia is depicted, almost stereotyped, as an arrogant person, due to the fact she is a representative of another country. Being a snob from a noble family, she seems to think her country is far superior to other countries, and because of that, Ichika challenged her to a duel.
But, behind Cecilia's confident exterior lies a disturbed soul. Due to her father being a very insignificant person who has no role inside or outside the family, she desires to marry someone who is strong. Furthermore, being the sole heir of the family fortune after her family died in a train accident, she was forced to protect it from those who wanted to steal it.
After fighting with Ichika, she starts showing an interest in him (being the only man who did not back down from her challenge) and affectionately calls him "Ichika-san" (Ichika Dear in the English dub) which confuses him and annoys Houki when she started doing it. She tries to find ways to be alone with him (often using the excuse that as a gentleman, Ichika must keep his promises or perform duties of the sort), only to be thwarted by either Houki or her classmates, who once told her comically that they would not let her get ahead in getting his attention. She doesn't mind putting aside her usually arrogant attitude in order to get Ichika to help her do things she knows she could do herself or wouldn't have needed him to do as an opportunity to flirt with him, something the others are quick to point out and get jealous over.
She apparently has certain delusions of being alone with Ichika and tends to make "preparation" in the event they may happen. Although she does feel embarrassed when thinks about them, she doesn't see's herself resisting him if he were to make any moves of her. These usually lead her to make bold suggestion when Ichika doing anything in regard to her body (such as when he was rubbing sun oil on her back or giving her a massage, she ask him to do it on her butt for both) or wear lewd clothing that other girls tease her for wearing (including Chifuyu Orimura and her maid Chelsea Blackett). In Volume 6, when Cecilia won a massage from Ichika, she thought about either wearing the black lace lingerie she brought before or even not wearing any underwear at all for it, although she didn't do either. As well, during the massage, she ask if she should undress the lower part to make it easier to massage, something Ichika compares her Tatenashi for saying.
She has also showed "yandere" tendencies with Lingyin as shown in episode 9 while they were stalking Ichika while he was out shopping with Charlotte and in episode 12 after the battle where she almost succeeded in shooting Ichika point blank in the head with one of her optical drones when he was about to kiss Houki as well as maybe causing a "flesh wound" as payback against Ichika. At the end of Volume 2 (equivalent to the end of episode 8), a difference was when Laura kissed Ichika, Cecilia attempted to snipe Ichika when he was trying to escape.
Her knowledge of IS is suggested to be high, as she was able to score high on an aptitude test at a very young age, thus earning the government's attention and gaining her a personal IS, Blue Tears.
As an A-Rank pilot, her skills are top-notch, being able to handle opponents by overwhelming them and avoiding attacks that can knock others down, although her overconfidence can sometimes undermine her skills and make her susceptible to certain attack styles that can be avoidable. In Volume 5, she considers herself to be the weakest among the girls as well as Ichika since she's the only one who should've lost to Ichika (only winning by a technicality). Also due to the nature of her unit (Blue Tears being able to attack multiple enemies without support from another IS), she does not know much on group formations and strategies. Later in the light novel, she learned to bend her laser beams at certain angles to give her an edge.
Outside of combat, Cecilia is skilled in other areas. She is said to be good at playing the violin and piano. She is also a skilled tennis player, being able to win the tournament held by the tennis club at the IS Academy.
- Her IS, Blue Tears, is a possible throwback to ZGMF-X20A Strike Freedom Gundam from Gundam SEED Destiny due to a similar color scheme and weapons. The "Bits" are similar to Strike Freedom's DRAGOON System, the rocket launchers at the waist imitate Strike Freedom's waist railguns, and its long sniper rifle is a possible homage to Strike Freedom's combined Beam Rifle.
- Note that Blue Tears may also be a homage to GN-002 Gundam Dynames (no optical drones/shield bits) and GN-006 Cherudim Gundam (has optical drones/shield bits) from Mobile Suit Gundam 00 due to the sniper rifle, the green jewel present on Cecilia's hairband might be homage to Dynames' Sniper Mode camera.
- Blue Tears - Cherudim
- Both have a sniper rifle, sniper mode camera, hidden missiles compartents and optical drones/shield bits. However the differences are the design of the optical drone is more closer to the designs of the fang weaponry in Mobile Suit Gundam 00 only lacking the ability to act as homing daggers (as in it is a missile that pierces you instead of exploding), the Cherudim Gundam does not have to be stationary to be the shield bits.
- It's also possible that Blue Tears pays homage to Kira Yamato's Gundams in general, as it is stated the Blue Tears can be equipped with packs just as the Strike Gundam could. One of the packs available for Blue Tears is also called Strike Gunner, which resembles the Gunbarrel Striker pack that can be mounted on either the Strike Gundam or the mass-produced 105 Dagger
- Her cooking is very bad despite its good looks. This is not just a cliché of the English cooking skills, but also a characteristic of Himeji Mizuki from Baka to Test to Shokanjuu.
- Her character is reminiscent of Ayaka Yukihiro from Mahou Sensei Negima and Saber from Fate/Stay Night, also she little bit like Atago from Kantai Collection.
- As seen in Volume 8, Cecilia thinks herself that she is where she's the CEO of her family company and Ichika is her personal butler, childhood friend and future marriage partner. Sign of this can be seen by how she always tries to get Ichika to serve her.
- She has a similar appearance to Urataros
- She makes a cameo alongside Lingyin in the manga Kampfer chapter 34.
- She makes a cameo alongside Charlotte in Maken ki chapter 60.
- Cecilia's birthday is confirmed to be December 24 in volume 11.
