Artist's commentary
It's different here than on the mainland. If you get shot down, beware of ⑨
Aya: The welcoming party's come out for us.
Cirno: Enemy aircraft overhead! Prepare for anti-aircraft engagement!
896: What, are you a ⑨? Aren't you getting it wrong?! I'm an Easy Shot*.
(postscript added 10/26: 896 = Yakumo)
a glitch in ace combat means that "easy shot" is anything but that.
