Eila Ilmatar Juutilainen (エイラ・イルマタル・ユーティライネン, Eira Irumataru Yūtirainen?) is a witch of the [[501st Joint Fighter Wing]], originating from [[Suomus]] and affiliated with the Suomus Air Force. She is referred to as "Illu" by her friends, and is sometimes named Diamond Ace. Her familiar is the black [[fox]].

Eila's magic ability Foresight (未来予知, Mirai Yochi) grants her a limited ability to predict the future. Her hobby is fortune-telling with tarot cards, although the accuracy of her predictions is questionable at best. Similar to stereotypes of her familiar (the black fox), she has a reputation for mischief, being fond of pranks amongst her colleagues and is somewhat mischievous.

Eila is often partnered with 501st Night Witch [[Sanya V. Litvyak]], and perhaps as a result (perhaps it is simply chemistry) the two have become very close; Eila is often portrayed as fiercely protective of her younger squadmate and takes on a sometimes awkwardly nurturing role during down-time. Whether this interest is romantic or plain, big-sisterly fondness is up for interpretation. 

Eila is based on the #1-ranked Finnish flying ace (and #1-ranked non-German flying ace) "Eino Ilmari Juutilainen":http://en.wikipedia.org/wiki/Eino_Juutilainen. Like Eila, he bore the nickname "Illu" amongst his friends. Her magic ability, Foresight, is a reference to Eino having never been hit by enemy fire.

She has an older sister, [[Aurora E. Juutilainen|Aurora E. Juutilainen]].
