(Honkai World Diva - Mika Kobayashi)

https://youtu.be/s_ZLfaZMpe0

Vanessa: Despite living in the world of ravaged by the Honkai, losing her mother at a young age and undergoing therapy for 3 years after getting kidnapped by a terrorist organization, Raiden Mei lived a good life as the daughter of ME Corp CEO Ryoma. Being an heiress meant Mei had everything on a silver platter: servants making her food, had a lot of friends and admirers at school, and even took kendo lessons. Mei basically had it all.

Adam: Until Anti-Entropy member Cocolia framed her father for embezzlement, which to his arrest in 2013 and possible demise and Cocolia took over the corporation as a result. Because of this, Mei as ostracized by everyone else due to her status as a "criminal's daughter" which led to her being an outcast. Mei realized they only cared because of her status and not who she is. This bullying continued until a voice in her promised power. This is actually related to her stigmata which had been sealed. And so Raiden Mei became the Herrscher of Thunder, igniting the 2014 Third Eruption in Nagazora, killing millions in the process.

Shadow: But she would be stopped by one girl, Kiana Kaslana, who met Mei at one point and even defended her from her tormentors. After a long battle, Mei was horrified by what she's done and tried to commit suicide by jumping off the roof, but Kiana grabbed her hand and saved Mei's life. This action brough Mei's human conscience back and they quickly became best friends.

Adam: Together with Bronya Zaychik, who unknown to them was tasked of capturing Mei, they fled Nagazora and was found by Himeko Murata and enrolled into St. Freya Academy by the principal Theresa Apocalypse to become Valkyries, superhuman defenders who defend the world from the threat of the Honkai.

Raiden Mei

Skilled Swordsmanship

High resistance to Honkai energy

Near-limitless Honkai energy reserves (In her Herrscher forms)

Gem of Conquest

Authority of Conquest

Authority of Origin

Various katanas (Nue of the Shadow, Seven Thunders of Retribution: Narukami, Domain of Sanction, Domain of Unity)

Time Fracture (Slows down time upon dodging correctly)

Immunity to Time Manipulation

Thunder Manipulation

Spatial Manipulation

Fate Manipulation

Battlesuits (Crimson Impulse, Valkyrie Bladestrike, Striker Fulminata, Danzai Spectramancer, Herrscher of Thunder and Herrscher of Origin)

Can summon Kurikara (As Herrscher of Thunder)

Adam: Thanks to her kendo lessons with Mr. HOMU, who is actually Ryoma in disguise, Mei became extremely skilled in all things katana and blade, possess superhuman strength, speed and durability and has control over lightning. And due to females having more significant roles in the Honkaiverse, Mei is able to both utilize Honkai energy and possess high resistance to it. She also has battlesuits and stigmatas to choose from which upgrades certain skills or give her new abilities overall.

Popup: Most Valkyries can utilize Time Fracture, which allows them to slow down time if they timed their dodging correctly and launch a counterattack. Mei should be capable of doing the same.

Shadow: She possess various katanas over the course of her years, from Nue of the Shadow to her godly Domain of Unity. But now let's to Mei's trump card: her Herrscher powers. With the Gem of Conquest, Mei can fully tap into her Herrscher of Thunder form., which increase her lightning-related abilities up to 11. Herrschers are also known be capable of creating entire solar systems, tank supernovas without ease and can survive reality itself being erased. And she has the ability literally called "Authority of Conquest" which has the power to resist Mei's powers being stolen or revive Judgement-Class Honkai Beasts like Bella, who she reconstructed into Kurikara.

Vanessa: Oh ho, but we're not done just yet. After joining World Serpent to save Kiana's life, Mei met and bonded with a girl named Elysia, who is the first Herrscher of the Previous Era to retain her consciousness without going insane and after fighting both the Elysian Realm and real Elysia to a draw, Mei merges with Elysia and becomes the new Herrscher of Origin.

Adam: Herrscher of Origin Mei possess power over space and time. Not only can she cut through space and time with ease, but shatter reality itself upon doing it. And since her powers originally belonged to Elysia, it's fair to say Mei can also do whatever Elysia can, which includes the ability to control fate itself.

Became the Captain of Squad 3 of Anti-Honkai Special Forces in (APHO)

Defeated Lucheni of the Sky People alongside Adam, Carole, Bronya, Lyle and Timido (APHO 2)

Shadow: Mei has proved why she's no longer the powerless person she thought she was. She has destroyed countless Honkai Beasts and Anti-Entropy mechs, defeated World Serpent member Raven one-on-one and the trio fought Wendy who, with the Gem of Desire, was capable of leveling cities if she wasn't stopped. Since the town they were in is Queenstown in New Zealand and the fact it's stated she can destroy several cities which means 3 at least, thus the nearest cities being Alexandra and Wanaka, Wendy was capable of outputting 99 Teratons of TNT.

Adam: She can also keep up with the likes of Fu Hua and Durandal. Fu Hua has dodged Gamma light beams which puts her over twice the speed of light and Durandal has maintained peak combat performance for an entire month without rest. Mei also defeated Kiana one-on-one in a duel between Herrschers. Sure Kiana was weakened before their fight, but still impressive considering Kiana's Herrscher of the Void form can control space and time prior to Mei getting her Origin form.

Vanessa: Keep in mind, Herrschers can perform absurd feats such as tanking supernovas, and resist being erased upon stepping foot in the Imaginary Tree, an infinite multiverse that will erase normal people with ease and even eradicate them from the timeline a sit ignore the rules of reality itself, yet Herrschers have no such problems.

Adam: And though on the verge of defeat, Mei still manages to held her own against Kalpas, the 3rd strongest Flame-Chaser behind only to Kevin and Elysia. Kalpas claims he can one-shot most Previous Era Herrschers in his Active Honkai Reaction state. And since she's fought Elysia to a standstill in both duels, it's only natural she'd scale to Elysia herself. Elysia could move stars in the Land of Origin. And both her simulation self and the Elysian Realm survived their presence literally being deleted by the Herrscher of Corruption.

Vanessa: We can also compare Mei's Herrscher of Origin to Kiana's Herrscher of Finality and even surpass Durandal's Dea Anchora, which contains a bubble universe and get this, she said it was unbelievably light! You heard me right. She wears a fricking armor that harbors a parallel universe and says it was light to her!

Popup: Durandal was capable of wiping out 1/5 of Europe at the age of 12. This would require power over 90.63 Petatons of TNT at minimum.

Shadow: And together Mei, Kiana and Bronya defeated Kevin Kaslana, who seeks to initiate Project Stigma and possess the Authority of Finality, once and for all.

Weaknesses

Once lost the Gem of Conquest to Sirin

Inferiority complex

Honkai reserves are not infinite

Defeated by Sirin, Durandal and Raven

Nearly killed by AHR Kalpas had Aponia not intervened

Nearly killed by Husk: Nihilus

Unknowingly brought the Herrscher of Corruption to the Elysian Realm after her encounter with the Will of the Honkai

Severely injured by Code XXI and nearly had her remaining Herrscher energy taken had Adam not saved her

Vanessa: But Mei still suffers weaknesses. Due to her past, she suffers severe inferiority complexes, always seeing herself powerless as those who cared for her got injured. This has what led to her nearly being killed by Kalpas had Aponia not arrived at the last minute. And while she has high resistance to Honkai energy, she can still succumb to it should she push past her limits.

Adam: And not even the ability to control fate can't grant Mei what she desired most: to be by Kiana's side. Being the current Herrscher of Finality, Kiana must leave Earth and seal herself on the moon to give Earth time to heal, leaving most of her friends.

Shadow: But Mei would not be alone in mourning. With her friends, Mei would continue protecting Earth for Kiana's sake and even became a Captain to a new Squad in the APHO timeline, becoming a mentor to Adam and Carole Peppers, a pair of students not unlike her and Kiana not-so long ago. And perhaps one day, she will finally be reunited with Kiana once again.

Adam: So let this be a lesson to never cross paths with the Empress of Lightning or you will find yourself at the end of her blade.

Mei: If rescuing you is a sin, I'll gladly become a sinner.
