Cross of Destiny (Cross Ange x Male Reader)

A boy named Seth Sifuguska had just turned sixteen when his family was slaughtered by a mysterious machine. Fueled by vengeance, he swore to destroy it. But his path was abruptly diverted when he was taken to the island of Arzenal-a militarized facility where he was forced to fight against airborne creatures known as DRAGONs.

Months later, a disgraced princess named Angelise, a Norma like him, was also conscripted. At first, Seth disliked her brash attitude, but over time, he warmed up to her-partly because he had no one else. He was the only male on the entire island.

After gaining control of a rare Gun-Mail unit known as Destiny, Seth made a new vow: to use its overwhelming power to eradicate the DRAGONs and hunt down the one responsible for his family's death-the man behind the machine, a being known only as Embryo.
