André Gide

André Gide (アンドレ・ジッド,) was the leader of a criminal organization from Europe known as Mimic.

Due to his actions in Dazai Osamu and the Dark Era, he is considered as one of the main antagonists.

Appearance
Gide was a tall man described as 'handsome' by Odasaku himself. He had sharp grey eyes, grey hair swept entirely to his back with only a few bangs hanging on the front from the sides and pale skin. Over his normal clothes, much like any other member of Mimic, he wore grey rags.

In the anime adaption, Gide had tan skin, red eyes, longer hair which was tied and he donned a grey cloak.

Personality
Befitting a soldier, Gide was a cold and serious man with amazing leadership skills. As a soldier, he was a righteous and prideful man, smart enough to seize a walled city with 600 enemies with only 40 soldiers.

Initially, he displayed himself as an emotionless man, only seeking the thrill from war in order to be finally killed by his enemies. He rarely showed any emotions, being Oda Sakunosuke the only one whom he shown his true character. While he might appear as extremely ruthless, he showed regretfulness and melancholy for his actions. He also constantly praised Oda and his skills, being one of the few persons who understood him and his reasons for not killing, enough to genuinely smile at him during their last moments alive.

Ability
It is revealed in one of the official promotional poster that his ability's name is 'Strait is the Gate (La Porte Étroite; 狭き門 - Sekimon) '. His power is exactly the same as Odasaku's, allowing Gide to predict the future for roughly five to six seconds as well.

In the anime, his ability's vision is shown in red color, contradicting Oda's blue.

Background
Gide used to be a hero, an astonishing commander from an unknown army during an unknown conflict called 'The Great War', until they were betrayed by their own country and labeled them as war criminals after attacking a walled city, not knowing about the peace treaties signed behind their backs. Therefore, their actions were unknowingly treated as war crimes and were on the verge of being annihilated, if not for they decided to take their dead enemies's possessions and disguise themselves as ghosts in order to break through their former allies's lines and escape.

Unable to find a reason to live out from the battlefield, he swore to his comrades that together they'd die as soldiers.

Before coming to Japan, he and his organization sought a war with the Knights  from The Order of the Clock Tower, but were ultimately expunged from Europe. Some time later, Mori contacted with them in order to lure them to the country.

Quotes

 * "We lost our homeland and our honour. We became ghosts wandering a wasteland in search of enemies to fight. (Oda asks: Are you sure you couldn't change your way of life?) I swore to my men that I would die a soldier. I cannot become anything else. No... Perhaps I could have. I may have been able to reshape my way of life and become someone who wasn't a soldier. Just like how you stopped killing."

Trivia
