Akeno could also be a leader. She is powerful and has her own ideas about how the underworld should be. She might be motivated by a desire to change the way devils treat each other and other races. And her relationship with Issei could play a role in gathering support for the coup. She could use her charm and power to sway others to their cause.
In a DxD fanfic about a coup against the underworld, there could be a major power shift. Maybe the devils' hierarchy gets completely overturned. New alliances might form between different factions that were previously at odds, like angels and devils working together against the old underworld regime. Characters could rise to unexpected power levels as they fight for a new order.
Avalanche members could be the main characters. They are already against Shinra's actions in the original story, so it's likely they would be at the forefront of a coup. Barret, with his strong will and leadership skills, could be leading the charge. Tifa, with her combat abilities and loyalty, would be a crucial member. Cloud, with his superhuman strength and his own vendetta against Shinra, would also play a major role.
Since I don't know the specific fanfic, I can't say for sure. But usually in a story about a coup against corruption, there could be a leader - type character who initiates the movement. There might also be a sidekick or a group of rebels who support this leader.
One possible plot could be that a group of rebels from the slums, tired of Shinra's exploitation of the planet's resources and oppression of the poor, secretly organize. They start by recruiting members within the slums, including those with unique skills like a skilled mechanic who can sabotage Shinra's machinery. Then, they plan to target key Shinra facilities, such as mako reactors. As they progress, they face internal conflicts about the morality of their actions, especially when some members suggest using extreme violence. Eventually, they might gain the support of some Shinra employees who have also grown disillusioned with the company's practices.
Well, without more context, it's difficult to say precisely. 'Coup against the corrupt fanfic' might be a fan - created story where the plot revolves around a revolt against a corrupt regime or power structure within the world of the fanfic. It could be inspired by real - world events or just the author's imagination. For example, it could be set in a fantasy world with its own set of rules and power dynamics, and the characters are fighting against the corrupt forces that have been oppressing them.
It could be a young and ambitious devil who has grown tired of the old ways of the underworld. He might see the current power - holders as corrupt and decides to take matters into his own hands by declaring war.
One possible interesting plot could be that the devil has a personal vendetta against a powerful underworld figure in the DxD universe. Maybe this underworld figure wronged the devil in the past, and now the devil has amassed enough power to declare war. This could lead to epic battles, alliances being formed and broken among different factions in the underworld.
It could be a noble knight. Knights in Warhammer are often symbols of heroism and they would be a great fit to lead the fight against the 'ratkness'.
It could be Naruto himself. He has a strong personality and a lot of potential for growth in a new world like DxD. His journey to adapt to the DxD universe and its rules would be very engaging.
It could be an envious student who also discovers the 'gamer' aspect but uses it for evil. He might try to undermine the protagonist at every turn, seeing him as a threat to his own power - hungry goals.
