Description
Mei Raiden, also known as Raiden Mei, is the daughter of Raiden Ryoma, CEO of the Massive Electric Corporation, an Anti-Entropy subsidiary. Her early life in Nagazora City, Japan, combined privilege with isolation due to her father's demanding work and her mother's death during her youth. At 15, her father was falsely accused of economic fraud by Cocolia and imprisoned, freezing their assets and triggering Mei's social ostracization. This shifted her personality from cheerful to solitary and guarded.
A childhood kidnapping resulted in three years of mental health treatment. Later, during Nagazora's 3rd Honkai Eruption, Mei awakened as the Herrscher of Thunder, unleashing destruction and mutations. Her Herrscher persona manifested as cold and malicious, viewing others with disdain. Kiana Kaslana, immune to Honkai energy, confronted Mei on a school rooftop. Kiana's refusal to abandon Mei and her act of catching Mei as she fell moved both, allowing Mei to regain control and forging an unbreakable bond.
Post-eruption, Mei joined Schicksal and enrolled at St. Freya Academy alongside Kiana and Bronya Zaychik. A bomb was implanted near her heart to contain her Herrscher powers. At St. Freya, she became a diligent student and caretaker, renowned for her culinary skills. She anchored Kiana emotionally, worrying over her recklessness and supporting her with meals. Her Herrscher persona evolved into an ally, cooperating to protect Kiana when the 2nd Herrscher threatened Kiana's consciousness.
After the Herrscher of the Void incident—where Kiana vanished and Himeko was lost—Mei witnessed Kiana's physical decline and self-sacrificial tendencies. Disillusioned by her own powerlessness, Mei joined World Serpent to gain strength to save Kiana, fully embracing her Herrscher of Thunder form. She declared, "If rescuing you is a sin, I'll gladly become a sinner," and reaffirmed Kiana as her most important person before departing.
Within World Serpent, Mei adopted a colder, merciless demeanor while retaining underlying empathy. She formed complex ties, such as an uneasy alliance with Raven that solidified into trust during missions. She encountered the simulated Elysia in the Elysian Realm, initially wary but gradually uncovering truths about the Honkai and the Flame-Chasers. Her Herrscher powers expanded, enabling her to intimidate adversaries like the Herrscher of Domination through psychological tactics.
Physically, Mei has long purple hair, often hip-length, indigo eyes, and a tall, toned physique from swordsmanship training. As the Herrscher of Thunder, her eyes turn pink, and she gains red horns and elongated hair. Her battlesuits evolve from the school-uniform-inspired Crimson Impulse to the demonic Lightning Empress and the transcendent Herrscher of Origin.
Her personality centers on loyalty and quiet resilience. Years of loneliness deepened her commitment to bonds, especially with Kiana and Bronya, whom she protects fiercely. She struggles with self-worth, frequently neglecting her own needs for others. This contrasts with her strategic intellect and investigative aptitude, evident in piecing together fragmented intelligence during missions.
Later, as principal of St. Freya Academy in "A Post-Honkai Odyssey," she leads missions despite diminished Herrscher abilities. Her leadership style remains grounded in compassion, reflecting her enduring dedication to nurturing others.
