Suletta

A girl from the asteroid belt who refuses to let a war decide who she is.

Suletta Mercury is the protagonist of Mobile Suit Gundam: The Witch from Mercury (2022–2023), a young girl from the asteroid belt who enrolls at an elite academy in the Capital. She becomes the pilot of the Gundam Aerial, a powerful mobile suit whose origins are tied to a deep social and political divide between the wealthy space-colony elite and the marginalized residents of the asteroid belt.

Her story is less about a chosen-one narrative and more about a girl trying to protect the people she loves while being pulled into a conflict she never sought. Suletta embodies the series' central question: can one person's courage bridge a chasm that entire institutions have built and maintained?

Lore & Background

Suletta grew up in the asteroid belt, a region of space where millions live in cramped, resource-scarce habitats far from the gleaming Capital. Her world is one of hard labor, limited opportunity, and a persistent sense of being looked down upon by those who enjoy the Capital's comfort. When she gains the chance to attend an academy in the Capital, it is both a dream and a collision: she is suddenly surrounded by peers whose families have shaped the very systems that keep her people on the margins.

The Gundam Aerial enters her life as both a gift and a burden. The mobile suit is connected to research and technology that the Capital's elite have hoarded, and Suletta's piloting of it makes her a symbol—whether she wants to be one or not. Her bond with Mikaji, a close companion who stands beside her through every crisis, grounds her in something personal amid escalating political violence. Together they fight not for ideology or territory but for the right of the people around them to simply live with dignity.

The series frames Suletta's arc as a coming-of-age story set against the backdrop of near-future space warfare. She is not a soldier by training or temperament; she is a student, a friend, a daughter. The fact that she can and does pilot a Gundam in combat is the extraordinary, not the ordinary. Her moral clarity—insisting that no one should be dehumanized by their birthplace or wealth—cuts through the series' more cynical factions and gives the narrative its emotional center.

Reader's Guide

Suletta Mercury is the emotional and moral axis of The Witch from Mercury. She pilots the Gundam Aerial, a mobile suit whose existence is entangled with the Capital's monopoly on advanced technology. Her arc moves from a wide-eyed asteroid-belt girl trying to fit in at a Capital academy to a young woman who must confront the violence her world inflicts on her own people and the people she loves. She is not a commander or a strategist; her power is relational—she fights because the people beside her are in danger, and she refuses to let institutional logic erase their humanity.

Mikaji is her closest companion and the steady counterweight to her impulsiveness. He walks beside her through every escalation, and their bond—whether framed as deep friendship or something more—anchors the series' hope. He represents the idea that solidarity across the Capital/belt divide is possible, even if the structures around them say otherwise.

The antagonistic forces in the story are less about individual villains and more about systems: the Capital's elite, the research institutions that treat the Aerial as a project rather than a person's burden, and the political machinery that keeps the belt in subjugation. Suletta's conflict is with all of these at once, and her moral position is consistently one of protection and refusal—refusal to accept that some people's comfort must be built on others' erasure.

Gally and the wider circle of friends and classmates give the story its texture of everyday life: shared meals, training mishaps, small kindnesses. These moments make the larger conflict feel personal rather than abstract, and they remind the audience that Suletta's world is not only hangars and battle damage but also laughter in a dormitory corridor.
