Aoyama no Hahaoya

Yuga's mother is affectionate, anxious, emotional, and intensely protective of her son.

Her decision to seek a Quirk for Yuga comes from watching him suffer because he is Quirkless rather than from a desire for social power. She wants him to feel ordinary and capable of pursuing the same dreams as his peers.

The family's bargain leaves her terrified. She understands that All For One can kill all three of them if they refuse his instructions, causing her to participate in decisions she visibly regrets.

When the truth emerges, her distress comes from both fear of punishment and guilt over what their choices have done to Yuga and his classmates.

Yuga's mother has no established Quirk.

She has no known combat training, hero career, or demonstrated superhuman ability.

The Aoyama family's wealth gives her access to resources unavailable to many civilians, but those resources become irrelevant once the family is dealing with All For One.

Her narrative importance comes from her role in Yuga's childhood and the coercive arrangement surrounding his Quirk.

Yuga's mother and father discover that their child is Quirkless and eventually establish contact with All For One.

He gives Yuga Navel Laser, allowing the boy to pursue heroism but leaving his body poorly adapted to the transplanted Quirk.

All For One later demands information from the family and threatens them with death if they refuse, forcing Yuga into acting as a mole inside U.A.

Toru Hagakure overhears the family discussing the situation and alerts Izuku, leading to the exposure of the U.A. traitor.

The heroes subsequently recognize that the frightened Aoyamas may still be useful against All For One.

The family participates in the deception that brings All For One into the heroes' planned opening battlefield during the Final War.

Yuga Aoyama is her son and the person whose suffering motivates the family's original decision to seek a Quirk.

Aoyama no Chichi is her husband and partner in the family's dealings with All For One.

All For One gives Yuga Navel Laser before coercing the entire family into serving his interests.

Tooru Hagakure overhears the family's secret conversation.

Izuku Midoriya helps convince Yuga that his forced cooperation with All For One does not prevent him from choosing a different path.
