Hero Faction

The Hero Faction (英雄派 Eiyū-ha) was the second-largest faction of the Chaos Insurgency led by Cao Cao, the descendant of Cao Cao from the Chinese novel Romance of the Three Kingdoms and the one of the two who betrayed Satanael and Wagyl.

Summary
The Hero Faction was one of the factions in the Chaos Insurgency that consisted of solely Humans. All members of the Hero Faction were either Ancient Gear, Holy Sword, Demon Sword, and/or Longinus wielders.

The motto of the Hero Faction was to fight and defeat "evil beings" such as Vampyres, Devils, Fallen Angels, Succubi and Incubi, and Dragons that bring harm to Humans, but also are enemies with the Hero Clan. The Hero Faction possessed a large number of Ancient Gear wielders who were either abducted and brainwashed, or followed willingly. Many of these members, however, were sacrificed in battle during the Hero Faction's attempts to force them to achieve Overdrive. All of those who didn't reach Overdrive were eventually captured and later died as a result of Wagyl's Snakes destroying their Ancient Gears, while those who did achieve Overdrive were called back before they could be caught.

The Hero Faction went inactive after Volume 13 after the loss of their leaders. Indra sends their most powerful members (Cao Cao, Guan Yu, Alice, Georg Faust, Cardinal, and Fionn) to the Realm of the Dead, taking all of their Longinus from them. Helen, Hercules and Sigmund Sellzen were captured by the Vampyres and Fallen Angels for interrogation, with Sigmund being sent back to the Hero Clan, while Charlemagne was the only main members of the Hero Faction who died in battle.

Trivia

 * Practically almost every Hero Faction member shown wears matching uniforms similar to that of a Japanese school uniform (more specifically, the gakuran worn in the fall).
