Elysia — Honkai Impact 3rd

In the recovered memories of her childhood, a gardener finds a nameless pink-haired girl asleep beneath an ash tree near the village of Vostok 51. Celia, who runs the local orphanage, raises her among children and neighbors who welcome her without knowing where she came from. She delights in flowers, stories, and the world around her, yet refuses the names suggested for her until Celia gives her a picture book describing a paradise called Eternal Elysium. The girl chooses the name Elysia for herself.

Repeated visits from outsiders investigating an unexplained anomaly make Elysia uneasy about what might happen to the villagers who took her in. She asks Celia to let her travel beyond the village and speaks of seeking the paradise from her storybook. Celia supports her decision, although the full significance of those investigations becomes clear only much later.

Elysia’s history turns the apparent chronology of the Previous Era upside down. She was not a human who unexpectedly transformed into the Thirteenth Herrscher: she was born a Herrscher, before the sequence of Herrschers normally counted in the era. The “Thirteenth” designation hides the truth about the Herrscher of Origin, also called the Herrscher of Human. Unlike the other Herrschers who devastated her era, she loved humanity and chose to stand with it.

That secret also changes the meaning of her work within MOTH. Her affection for the Flame-Chasers was not an elaborate disguise for hostility; she genuinely wanted people with incompatible personalities to be recognized together. The group’s difficult history and the increasingly desperate war give her dream of a united company its tragic urgency.

After the Tragedy of Binding, only thirteen MANTIS fighters were left. Elysia proposed recognizing all thirteen as the Flame-Chasers, but MOTH’s leadership offered to approve only five. She refused to leave the other eight behind. The thirteen continued to identify as Flame-Chasers even without formal approval, which explains why belonging mattered more to Elysia than organizational recognition.

Near the end of the Previous Era, Elysia arranged her final summons as a banquet even though the public story would frame it as a mission against the alleged Thirteenth Herrscher. There she disclosed her real nature to those who attended. The tale of Kevin defeating her in an ordinary fight was a cover story, not a faithful account of how Elysia chose to depart. She turned a confrontation into a farewell because she wanted her final choice to leave hope for humanity.

The story links her self-sacrifice to a crucial difference in the Current Era: later Herrschers can retain human feelings and choose to fight for people rather than automatically act as instruments of destruction. This is the larger significance that Mei eventually discovers behind the carefully concealed account of Elysia’s last days.

In the later Elysian Realm chapters, Mei reaches Elysium Everlasting and gains access to more personal memories of the Flame-Chasers. Elysia promises to explain the Thirteenth Herrscher, but her simulation disappears before she can do so. The destruction of memories and the apparent deaths of multiple simulations turn the search for truth into a crisis involving the Herrscher of Corruption.

The Herrscher of Corruption infiltrates the memory world, takes on a distorted likeness of Elysia, and threatens to erase the Realm from within. Mei and the surviving simulations gather memories in an effort to reconstruct her. Eden ultimately contributes not only her recollections but her own simulated existence, completing the restoration.

The restored Elysia joins the remaining Flame-Chasers in their final resistance. Their combined effort defeats the Herrscher of Corruption at the price of the Elysian Realm itself. The official animated short Because of You dramatizes the confrontation and the unity of the thirteen, while Mei is able to leave carrying what she learned from them. The memory simulations’ destruction should not be mistaken for a new death of the long-departed original Elysia.

Kevin later explains the personal reason behind Mei’s journey: he wanted Elysia’s legacy to encounter a Herrscher of the Current Era who had chosen humanity. That meeting answers, in retrospect, the uncertainty Elysia had once felt about how others would accept her.

The storyline does not end with the disappearance of the simulation. During the Moon’s Origin and Finality arc, Raiden Mei’s connection to the Authority of Origin leads to another encounter with Elysia’s presence. The Flame-Chasers’ Signets and wishes frame Mei’s emergence as the new Herrscher of Origin, carrying forward the possibility that Elysia left to her successors. This later encounter is not evidence that the original Previous Era Elysia simply returned to ordinary life.
