- "IDOLMASTER, Miki Hoshii aircraft. Hundreds of hours of tuning have transformed this aircraft into a superstar. Although a little difficult to control, it performs like no other. A true example of what can be achieved when hidden potential is realized."
- ― Official description
The Miki-EX aircraft provides a small increase in air-to-ground/air capabilities and speed, while maximizing mobility, while defense is slightly lowered and stability suffers a massive cut. Missile payload is decreased from 250 to 159, while SP weapons payload is increased. The Miki-EX's most notable feature is its maneuverability; when going over 600 miles, the aircraft gains extreme mobility, allowing it to drift in mid-air similar to the CFA-44 Nosferatu. This increase in mobility even allows a skilled pilot to perform a Herbst maneuver by performing a High-G turn at full speed.
The Su-47 Miki-EX has garnered negative reception from the AC community, as the aircraft's physics-defying mobility, combined with its high QAAM count allows a pilot to rack up thousands of points.
- The Su-47 Miki-EX makes Miki Hoshii the only Idol to be featured in more than a single aircraft.
- In the plot of THE iDOLM@STER, player character Producer-san saves Miki from being run over by a speeding truck. Feeling guilty for the character's injuries, this moment triggers a massive change of personality on Miki, who becomes a hard-working and strong-willed idol, known as "Awakened Miki". The Miki-EX's description and performance (when compared to the Miki Flanker's) allude to this new Miki.
