Eila Ilmatar Juutilainen is one of the main supporting characters from the Strike Witches anime series. She is an Flying officer in the 501st Joint Fighter Wing.
She is voiced by Ohashi Ayuru (aka Nakai Erika) in the Japanese version of the anime, and by Caitlin Glass in the English version of the anime.
Eila is based on the #1-ranked Finnish flying ace (and #1-ranked non-German flying ace) Eino Ilmari Juutilainen. Like Eila, he bore the nickname "Illu" amongst his friends.
Her magic ability Foresight grants her a limited ability to predict the future. She can sense and dodge enemy fire with relative ease and anticipate their movements. However, the ability seems to be focused on the near future and her projections on more complicated issues have been imprecise.
In practice, Eila's unique style presents a fear for her superiors: there is some concern that, being effectively untargetable by enemy weapons, she has grown out-of-practice or careless with regard to other combat essentials, such as use of her shield. Lacking the same sense of danger, she can forget the vulnerability of her squadmates and the importance of teamwork.
