Eila Ilmatar Juutilainen, a witch from Suomus—a Finland-inspired nation—commands recognition as a top ace in the Suomus Air Force. Her distinguished career launched in the elite 24th Squadron, where she received the Mannerheim Cross, Suomus’ highest military honor, and forged enduring bonds with fellow soldiers like Nikka Edvardine Katajainen. Renowned for her elusive combat tactics, she earned the callsign “Ace of Diamonds” from her Striker Unit’s diamond emblem before transferring to the multinational 501st Joint Fighter Wing via an exchange initiative. Her magic, Foresight, grants momentary glimpses into the future, enabling precise evasion and tactical anticipation of enemy actions. This ability, paired with sharp analytical skills, renders her nearly invulnerable in battle. However, her focus on predictive dodging drew command scrutiny for underusing shields—a habit counterbalanced by fierce protectiveness toward allies, particularly Sanya Litvyak. Eila exudes playful mischief, delighting in pranks and teasing peers like Nikka and Perrine H. Clostermann. She dabbles in tarot-based fortune-telling, though her readings prove notoriously inaccurate. Beneath her jesting exterior lies deep-rooted loyalty, most evident in her bond with Sanya. Their connection, blending camaraderie and ambiguous romance, evolves from shared Striker Unit repairs to nocturnal patrols and joint missions in Suomus, where Eila aids Sanya’s search for her missing parents. After the 501st disbands post-Gallia’s liberation, Eila and Sanya redeploy to Kauhava Base under the 507th Joint Fighter Wing. A later Orussian vacation is cut short by renewed conflict. She stays linked to former 501st members and allies from units like the 502nd, occasionally visiting them. Her Striker Units progress from Brewster F2A Buffalo to Messerschmitt Bf109 models, all bearing her diamond insignia. Family ties include an older sister, Aurora E. Juutilainen, a seasoned land witch, and a mentorship dynamic with Elma Leivonen. Cultural touches like sauna traditions and a distaste for herring—linked to unpleasant memories—round out her persona. Post-war, she engages in cross-unit operations against Neuroi threats, underscoring her adaptability and enduring dedication to global defense efforts.
