A dagger from Xenon's childhood

Beryl leaves Xenon

A young boy once disappeared from Edelstein while walking home after playing Mesorangers with his friends. Abducted by Gelimer, the chief scientist of the Black Wings, the boy's memories were seemingly erased and he was made into a test subject for advanced cyberization.

Several years later, the leaders of the Resistance broke into one of Gelimer's labs, but one of them - Claudine - was captured. The kidnapped boy, now a superhuman cyborg named Xenon, was disturbed and confused. A memory started coming back to him: Claudine was one of his childhood friends. Puzzled by this revelation and wanting to unlock more of his memories, he freed Claudine and they fought their way out of the lab along with Xenon's cyborg friend Roo-D.

Freed from captivity, Xenon sets out on a journey to regain his humanity.

Class Specifics

Read more: Xenon Skills

Xenon is a more complicated class, being a mix of Thief and Pirate; he can wear both their equipments and is fueled by the three stats they use: Strength, Dexterity, and Luck. These stats strengthen Xenon's Multilateral I, Multilateral II, Multilateral III, Multilateral IV, Multilateral V and Multilateral VI, whereas Strength contributes to Knockback Resistance, Dexterity to Status and Elemental Resistance, Luck to Avoidability, and all three to damage.

The three stats complicates Xenon's stat distribution. Auto assign contributes to the stats individually rather than simultaneously. Once an auto assign has been picked, it cannot be switched until the current Multilateral's stats requirements have been met for that stat.
