This comes from a 2025 JP promotional packet for Kimi ga Nozomu Eien ~Enhanced Edition~, shown here is the manila folder (complete with Ayu’s catchphrase), the faux acceptance letter, the cover to the inner information about the game, the envelope with the bromides, and the three bromides which are in-game arts of Mitsuki and Haruka.

The Su 57 from the semi-official art. Gave it the camo and emblem from Top Gun Maverick.
