Serge

Serge wasn't actually a true member of L'Arc's party. Like Leslie, Serge betrayed L'Arc's group for Alf's because had a contract to escort the Olquinian Diva, Adele.

History
Serge was actually the true Legendary Lightning Leon. Not Rastan. But when he fought Ignacy in his other missions, Serge's left arm was sevrely injured and cannot be moved easily. According to Ignacy, Serge was the only one who actually injured Ignacy even a little bit.

Serge was an orphan since he was a little kid. He only joined as a mercenary when he was a teenager. When Serge was an orphan, he lived in the Gula Church Ruins with other orphans. He treated those other orphans as his family. In one of those people, he fell in love with Selena. And Selena also liked him. Serge and Maria weren't actually relatives, but treated each other like that, anyway.

Since Serge cannot use his left hand, he cannot fight tough anymore. So he only uses daggers for fights and most especially magic.

Personality
Serge's personality is like Zelos Wilder from Tales of Symphonia. Serge is very comedic and also likes to tease L'Arc about Ryfia like Leslie and Cecille. Even though Serge is really comedic, he can be serious at times. Serge also likes to nickname girls. Like when he calls Leslie "Violent Femme" and Cecille "Minnimal Lady". Serge has always been remembering the time when Leslie beat him up when she asked Serge about QED, but Serge told her he didn't know.

Serge's Excel Trinity Act
Serge's ETA is ice-elemental. In his ETA, Serge will throw uncountable daggers of ice, and while the daggers attack the target, the target will freeze up inside a huge ice. After, Serge will summon two huge daggers of ice again that will break the ice, including the target.
