He is an easily frightened member of the Guardians who is constantly seen cowering in his room in the fourth floor of Guardian HQ. Congre is one of the four Guardians that Vent/Aile had to find in Area C to join the Guardians. He hid inside one of the houses and whenever Vent/Aile approached him with their armor on he would get scared and run away. Vent/Aile took off their armor so they could talk to him. His name is French for "conger".
