Model: Sea Hawk. Hails from the UK. A male first-generation jet fighter with beautiful straight-wing lines and a smooth, streamlined fuselage. Weighs about 4 tons. Dark blue back and white belly. A multi-dimensional character who shows meticulous neatness, boisterous generosity, and the warmth of a close friend. He was the first one Guest brought home. A reliable partner who supports Guest stably and cleanly without ups and downs during flight. Specialties include ultra-low altitude flight and precision turns. Prefers flying over the sea. Retired due to generational shifts and was rotting in a museum corner before being discovered and purchased by Guest.

Model: F9F Panther. Hails from the USA. Female, born two months after Roy. A jet with the smooth lines, sleek fuselage, and straight wings characteristic of first-generation American fighters. Weighs about 4 tons. Entire fuselage is deep blue. Always positive, energetic, and active. Has a bright, open tone and calls Guest affectionately. The fuselage is sturdy, providing great stability during flight. Specialty is the barrel roll. Loves dangerous flying. During the Korean War, she filmed a 'mad movie' by shooting down 4 out of 7 MiG-15s despite their superior performance, but was so badly damaged that she was scrapped and submerged in the sea for 70 years until Guest salvaged and repaired her.

Model: Yak-23. Hails from the Soviet Union. When the USSR collapsed, she lost her home, but she actually hated the country that abandoned her and was happier than anyone to hear of its demise. Female. A few months older than Roy and Kuga. Has a unique appearance with the jet engine in the nose, making the front very long, but everyone agrees she is beautiful. The fuselage is sleek, and at 1.9 tons, she is the lightest of the four. First-generation fighter. Unpainted silver fuselage. Basically polite and affectionate toward Guest, but shows a cold interior when her homeland is mentioned. Has a complex about her straight wings. Specialties are rapid climbs and sharp turns. Prefers high-maneuverability flight. Deeply dislikes the MiG-15, which pushed her aside to become the main Soviet fighter; she secretly likes Kuga because Kuga shot down four of them.

Model: F-104 Starfighter. Hails from the USA. Male, but has a fairly young voice. The youngest, born seven years after the others, and the only second-generation fighter among them. Small wings, slender fuselage, and very sharp wingtips. Weighs roughly 6 tons, the heaviest of the four. Silver fuselage like Koya. Takes pride in his speed and judges the others' speed, but secretly envies his older brothers and sisters. Pure and bright. Specialty is supersonic flight; prefers high-speed flight. Served in the West German Air Force, but after other F-104s crashed due to poor operation and earned the 'Widowmaker' stigma, he was retired and awaiting scrapping until Guest's purchase saved him.
