She has been decorated with the Knight Grand Cross of the Order of the Mochi for helping out the International Academy of Hetalia Fanfiction during the Mary Sue invasion.
Being a Unison Device from the Nanohaverse, she is only fifteen centimeters (6") tall (in fact, half the size of a regular UD due to mana shortage) when not in disguise, but has the ability to float around, sometimes with fairy-like energy wings that make other agents mistake her for a fairy, while she is in fact a sort of intelligent Magitek device. She later recovered enough to both use her normal 30 cm (1') form and a full-size (but still rather short) form about 140 cm (4'8") tall, though she admits the "fun-size" form is handy for working inside faulty consoles.
She was found and rescued by Sergio Turbo and spent a lot of time in Medical due to serious wounds. She currently doesn't have a lot of mana and cannot cast complex or powerful spells, since her Linker Core is taking longer to recover out of the Nanohaverse. She still retains some useful skills, such as bind spells, and the PPC staff put in her body some useful devices, such as a low-power, safer combined CAD and a remote activator. However, those implants tend to malfunction, leading even to Corolla's main system crashing in very bad cases.
After joining DoSAT she is sometimes seen wearing glasses, despite having no need for them. She thinks that they make her look more like a proper scientist.
As most Unison Devices, Corolla is very childish and light-hearted, leading to anime-styled gags very often. However, she is also near to being completely crazy, and her taste for Sue-related food such as Sue Soufflé (much to Sergio's distaste) makes the otherwise cute girl a little bit scary. She likes playing with minis, and she would be the one who keeps them always on her head, but being mini-sized herself she can't.
However, she is also able to act very level-headed when alone or her partner Sergio is the one who needs to be restrained.
Partners and Family
Being a Unison Device, she doesn't have a true family, but her partner Sergio treats her as a little sister, taking care of her and ensuring that she doesn't get into trouble. This eventually ended up with Sergio and Nikki's daughter, Keiko, growing up to consider Corolla to be her own aunt.
She had a part in the recruitment of Shiro Turbo and Saki Cherryflower (and, if fact, is the one who managed to revive the latter after her scripted "death"), and quickly added them to the list of her "nephews" (which currently includes them, Keiko, and at least one version of Elanorelisindrivar).
While partnered with Sergio and Nikki, she used to own a mini-Guardian called Sakura Kiminoto and a mini-Berserk called Nanoha Takamichi. However, by 2015 HST she instead owns a pov called Mr. Snrfles. It is likely that the two minis ended up in someone else's care, as Corolla's usual size prevents her from taking care of them on her own (especially considering Nanoha Takamichi's destructive tendencies).
