Description
Hikari Myōdō is Akina Myōdō's younger sister. A decade before the series, she wandered off during a camping trip and became trapped in a cave-in. Though rescued alongside Akina, she contracted an unexplained illness that chronically weakened her constitution. This required frequent hospitalization and dependence on Akina for daily care. The illness's cause remained unknown to medical experts until it was revealed as Sybilt secretly draining her life force while possessing her body. Her condition stunted physical growth and isolated her from typical childhood experiences. Despite this, she maintained a cheerful, playful demeanor, often teasing Akina and watching Vanguard streams to cope with hospital life. Beneath this positivity, she harbored deep guilt over the cave-in accident and the burden her illness placed on Akina. She believed it forced him to abandon his dreams to care for her, reducing him to a "husk of a person," making this guilt a defining psychological aspect.
In an alternate timeline where Akina died after losing the Fated Clash to Suo Yobitsugi, a traumatized Hikari participated in a subsequent Fated Clash three years later. Winning it, she used her wish to travel back in time to prevent Akina's death. Disguised as "Fox Mask," she attempted to sabotage the original Fated Clash by threatening participants and manipulating events to force Akina's withdrawal or eliminate Suo. Her actions were driven by cold determination and resentment toward Suo and Gabwelius, whom she blamed for Akina's fate. When her schemes failed, she confronted Akina directly. Initially resistant, she ultimately trusted him to alter the timeline, leading to his victory in the Fated Clash and the curing of her present self's illness. This time travel created a temporal paradox causing her future self to gradually fade from existence and inadvertently enabled Sybilt's machinations in the revised timeline.
After Akina's wish cured her illness in the present timeline, Sybilt approached her with an offer to join the Destined Showdown, exploiting her unresolved guilt. Under Sybilt's mental suggestion, she became an owner of the Destined One of Time card, Liael゠Odium, fighting to fulfill her wish of traveling back to prevent the cave-in accident entirely. This corruption amplified her bitterness and resentment, leading her to avoid Akina and openly criticize his self-sacrificing nature. During the Destined Showdown, she fought Akina in the sixth round, revealing her view of herself as the "sinner" whose existence derailed his life, aiming to erase the accident so Akina could reclaim his autonomy. She defeated Akina using Odium’s Divine Skill to gain an extra turn, forcing a tiebreaker round.
In the tiebreaker, her future self (now the Fated One of Time) intervened as the seventh Fated One, wielding Liael゠Amorta. The two Hikaris clashed ideologically: the future self condemned the present self's plan as selfish, arguing it disregarded Akina’s agency and the genuine fulfillment he found in caring for her, while warning of time manipulation dangers by citing her own fading existence. Present Hikari rejected these arguments until her future self defeated her in battle, breaking Sybilt’s mental hold. This forced her to acknowledge Akina’s perspective, leading to reconciliation. She and Akina mutually vowed to support each other’s futures.
Following Sybilt’s defeat, the future Hikari faced permanent erasure due to timeline alterations. To survive, she merged with Gabwelius, accepting his power to sustain her existence. With the original Hikari Myōdō already present, she adopted a new identity: "Erika Myojo." The surname "Myojo" combined "Meisei" and "Kodo," while "Erika" derived from "Gabwelius" and "Hikari." As Erika, she joined the professional Vanguard team "Kiyokura ANCHOR BOLT" as a researcher, signaling a new chapter focused on self-discovery beyond her past fixation.
Hikari’s connection to the Vanguard card Liael reflects her struggles. As the avatar of Liael゠Odium, her card accumulated power through the "Regress Gauge," symbolizing years of repressed guilt culminating in her desire to rewrite history. As Liael゠Amorta, the card’s ability to rewind units mirrored her future self’s fixation on altering Akina’s death. Both forms embody her core trait: determination to rectify past mistakes regardless of personal cost. Her story concludes with dual resolutions—present Hikari embracing life with Akina, and future Hikari (as Erika) building an independent future.
