Pixy

A mercenary pilot who really fucking hates borders.

Belkan Warrior
A mercenary pilot from the conflicted nation of Belka in the mythical land of Strangereal who was orphaned during the fights and became an exceptional pilot afterwards. Eventually was contracted by the Ustian Military and became part of the 66th Air Force Unit "Galm Team" under flight lead Cipher. As the fighting went on, he became less motivated at having to attack his homeland, and kept affirming that it would only get worse. Lo and behold, his predictions came true when Allied Forces started targeting military and civilians alike. When the Galm Team failed to prevent the detonation of seven V1 warheads on Waldreich Mountains, he just felt like he couldn't continue to perpetrate the cycle of destruction.

After acquiescing the message sent to him by the enemy, he opened fire on Cipher and along the commotion from enemy forces managed to escape.

He disappeared for 6 months until resurfacing as a member of the rebel organisation "A World With No Boundaries" piloting an experimental aircraft, seeking to eliminate borders by launching a Multiple Independently Targetable Reentry Vehicle to target all the major cities in the Osean continent, causing an economic desbalance to unite all the nations. He was eventually beaten by Cipher and emergency landed on a small Belkan village, where he was nursed to health, and reenlisted to the Independent State Allied Forces.

Episode 4

Part 2
During one of his combats, a strange singularity engulfed Pixy's plane, and he awoke near the TFR ring. He didn't understand where he was or where was his plane, but he understood one thing: wherever there was borders, chaos and death would ensue. So Pixy joined TFR to gain enough power to destroy the concept of "borders".

Afterwards, it's said he left from the same distortion he came from, as he wasted enough time on a cursed land where the concept of borders couldn't be undone.
