Fan-made short videos have appeared in Honkai Impact 3rd, and characters have been created and sent

[Star: I fell a total of 23 times, roughly once every 10 steps.]

[March 7th: You're really quite boring.]

[Durandal: Your Excellency... do you simply wish to erect a blank monument?]

[Raiden Mei: I didn't expect Otto to mention Durandal besides the Headmistress.]

[Jing Yuan: Otto has feelings for everyone. His familial affection for Theresa is genuine, as is his teacher-student relationship with Durandal. He simply doesn't allow himself to "satisfy" these emotions.]

[Aha: Bianca, this is the final lesson.]

[Narcissus: Durandal previously told Otto that he had mentored her, which can be considered a consolation to Otto.]

[Black Swan: Perhaps no one can forgive Otto, nor does he need anyone to forgive him.]

[Zhongli: Life is too long, and epitaphs too short.]

[Paimon: Hmm... Is saving Kallen just Otto's wishful thinking? That's a bit disheartening.]

[Einstein: I once heard a saying—saving you is none of your business.]

[Raiden Mei: I will fall into darkness so that you may return to the light... For Otto, Kallen is more important than this world.]

Otto was a man who carried everything; he was covered in wounds, but he gave precious and warm light to the only woman in his heart.

[Bronya (Honkai Impact 3rd: Star Railway): I always felt that Kallen was more than just a lover to Otto; she was a kind of faith.]

[(Honkai Impact 3rd: Star Railway) Welt Yang: When a person is in despair and lost, even the slightest bit of tenderness and love may be their only salvation.]

In Otto's world, there is only Kallen as the sole light; for Otto, Kallen is his only world.

Karen preserved Otto's humanity, but with Karen's death, she also took Otto's humanity away.

From the moment Karen died, no light could ever penetrate Otto's closed heart.

[The animated short film begins, and Otto's somewhat somber voice rings out: "Only when a person truly wants to change the world do they realize how insignificant their individual power is."]

The scene on the screen shifted back 500 years, showing Karen being led by two nuns towards the gallows placed in front of the church.

It was a day of solar eclipse. The cawing of crows filled the air. The nuns in black robes, the ignorant masses, the gloomy sky… everything seemed oppressive. Only the saint, shackled and still pure white, remained.

[“The saint gave everything for the people, but in return, she was ruthlessly shackled and strangled.”]

Otto ignored the church beside him, which was exactly the same as the one from that day, and walked slowly but resolutely toward the Tree of Imaginary Numbers: "The world is so chaotic; it is neither fair nor reasonable."

"It persecutes heroes, breeds evil, spreads ugliness everywhere, and leaves no trace of beauty..."

As Otto advanced, the crimson sand began to churn, and countless figures crawled out from underground.

The sand that had covered the figures gradually crumbled, revealing their true forms—they were all wearing the same clothes as Otto, and they were all "Otto."

Looking at the monsters standing before him, trying to stop him, Otto, despite his battered and tattered bodies, still wore a disdainful smile.

The golden mimicry of divine fire appeared in his hand. Otto gripped the sword tightly, and flames, like his resolve, began to burn fiercely.

"Let the evil god sever the world's malice."

[Silver Wolf: These buildings in imaginary space look just like white models with outlines added in modeling software.]

[Silver Wolf: Every vivid character in the game started as a gray-black white model. Otto wanted to give Kallen a realistic world, hoping she could start her beautiful life anew. Perhaps these white models symbolize the starting point of Otto's wish.]

[March 7th: So many monsters! We're already here, do we still need to fight?]

[Paimon: There are so many Ottos in front of the Imaginary Tree... Where did these monsters come from?]

[The Black Tower: Perhaps it's a projection created by the Imaginary Tree based on Otto's consciousness to protect itself; perhaps it's one of the Ottos who failed to save Kallen. There are many possibilities.]

[Fireworks: Otto only has 1 HP left, can he win?]

[Star: We'll win! He's invincible!]

[Star: Good luck, Your Excellency!]

[Bronya (Honkai Impact 3): It's a pity this isn't an Ultraman movie set, otherwise what you said would have given Otto the victory outright.]

[Siegfried: It's alright, Otto still has Mimicry: Judgment of Heavenly Fire.]

Every time the Heavenly Judgment is drawn, it is for the sake of a beloved one.

Only those with the deepest emotions and truest nature can wield fire that moves the heavens.

[Tesla: Damn it, just this once, you bastard! Since you've come this far, you'd better hold out until the very end!]

[Aha: In any case, this is the end of 500 years of obsession. Enjoy the final act of the fool—the show has begun, let's give it a thunderous roar!]

[Time rewinds to 500 years ago. Karen is led to the gallows, ropes wrapped around her neck, and Karen merely sighs, remaining silent.]

Five hundred years later, Otto charged alone at the countless "Ottos" blocking his way. He leaped high into the air and then brought down the sword in his hand.

The flames erupting from the Heavenly Judgment shattered the enemy's formation, but the monsters continued to surge towards Otto like a tidal wave. The Heavenly Fire Greatsword in Otto's hands was ultimately a counterfeit; after a fierce swing, the fiery sword shattered.

Dark lines were spreading upwards along Otto's neck, and Otto was gradually becoming like the monster before him, but he simply gripped the newly conjured Black Abyss White Flower and pierced through one enemy after another.

"This is the distance between her and tomorrow, this is the world's relentless backlash against her, but her followers will never give up because of it."

Otto was not a god; he too could tire. The monsters seized the opportunity to pounce on him, so Otto decisively abandoned his lance and wielded the Mimicry Xuanyuan Sword to slay the surrounding monsters.

Seemingly realizing that a swarm attack tactic was ineffective, the monsters chose to gather together, coalescing into a gigantic Honkai Beast that roared at Otto.

Five hundred years ago, Kallen, standing on the gallows, also heard the roar of the Honkai Beast. She looked in the direction of the sound and saw the Honkai Beast that Otto had released.

The Honkai Beasts fell into the crowd of onlookers and began to slaughter them. Kallen couldn't stand by and watch this happen. She gritted her teeth, smashed the shackles on her hands with her knee, and used her freed hand to break the rope around her neck. Then, she fearlessly charged towards the Honkai Beasts engulfed in flames.

[Paimon: Otto... he's so strong!]

[Young Master: Yes, you could say he's proficient in all martial arts; it's truly exhilarating!]

[Silver Wolf: He only has 1 HP left, yet he can deal such massive damage. No wonder he's Otto.]

[Aha: Locked health, anyone?]

[Star: So what if it's open? Watch the Bishop clear the game without taking any damage!]

[Honkai Impact 3rd Himeko: Sigh, Kallen could have broken free of her shackles and torn the ropes, yet she willingly walked onto the gallows.]

[Otto: It's voluntary...]

Karen's "voluntary" act was not truly voluntary; she was manipulated by the ignorant masses, and one could say she was killed by that foolish era.

[Wendy: I ​​think if Karen wanted to escape, no one in that era could stop her.]

[Siegfried: Perhaps, but she won't run away, because Kaslana is the people's shield!]

[Rita: If His Holiness the Bishop is an extremely complex person, then Lady Karen is an absolutely pure one. She is a true saint; her kindness, courage, and will are second to none. Lady Karen truly deserves the title of saint.]

[March 7th: How wonderful... Perhaps only a saint like her could make Otto so devoted.]

[Kiana: Those who gather firewood for others should not be left to freeze to death in the snow; kind people should be treated kindly.]

[(Honkai Impact 3rd: Star Railway) Welt Yang: Perhaps Otto could never escape the day he would see the white-haired, blue-eyed girl. For that day, Otto desperately traveled against the flow of time—only the purest love can conquer time and overcome everything in the world.]

[(Honkai Impact 3rd: Star Railway) Welt Yang: The Honkai Beast that Kallen faced looked exactly like the one Otto faced, which can be considered Otto's inner demon.]

How much love must one have to transform a cowardly inventor into a world-ruling archbishop?

How much love must one have for an archbishop to give up everything for a chance?

Five hundred years ago, he met her; five hundred years later, he wielded the Heavenly Fire Greatsword to sever all ties of those five hundred years.

[Paimon: I'm suddenly curious what Kallen will do after she's resurrected.]

[Hanabi: Kallen: Otto, take down the Honkai! Honkai: Huh? I'm going to fight Otto? Really?]

[Aha: After Kallen was resurrected, she discovered that Otto was dead. Kallen then turned to the dark side in order to revive Otto. She obtained the Void Treasury and served as the Holy Maiden of Destiny for 500 years. She created two golden-haired homunculus using Soul Steel. These two homunculus later traveled to another world in search of Otto's golden light.]

[Aha: By the way, these two androids are named Sora and Luminous. It's said that whenever a golden light flashes, Kallen is one step closer to reviving Otto.]

[null:?]

[fluorescent:?]

[Sambo: Haha, fast forward to "Thus Spoke Kaslana".]

[Qingque: I feel like I'm going to throw up from the Honkai Impact 3rd. What are these two doing, taking turns playing games like this?]

[Star: The tree of imaginary numbers became part of the two people's play.]

Before the Tree of Imaginary Numbers, Otto was sent flying by the monster's powerful attack. Before he could regain his footing, the monster charged at him at a speed completely disproportionate to its size, slamming its fist down and kicking up dust.

The dust hadn't settled, but golden chains shot out, binding the monster's body. Otto, wielding the Mimicry of Judah's Oath, raced across the monster's arm, then leaped high, smashing its head open.

Otto's attack didn't end there; he unleashed Judas, piercing the monster with its light spears, rendering it powerless.

[Hoshino: The world's cutest strike!]

[Aha: Watch closely, Theresa, this is how Judah is used!]

[Fireworks: Do you know how many uses Judas has?]

[Kiana: I didn't expect Otto to use Judah so well.]

[Fu Hua: The Oath of Judah is the weapon Kallen used back then; Otto must have studied it for a long time.]

[Star: That's not surprising, that's not surprising at all.]

[Raiden Mei: When Otto smashed the monster at the end, Judas was upside down. If I remember correctly, the upside-down cross symbolizes disobedience to God.]

[It was a victory, but a Pyrrhic one. The already battered Otto was thrown back by the recoil, rolling haphazardly on the ground.]

But Otto simply gritted his teeth, stood up, and walked to the Tree of Imaginary Numbers.

His eyes held the same unwavering determination as Kallen's 500 years ago when she witnessed the Honkai Beasts about to unleash a new carnage.

[Kallen charged towards the Honkai Beast without hesitation, blood splattering as she shielded the child from its claws with her own body. At the same time, Otto was also pierced through the chest by a black spike.]

The source of this black thorn is the enormous Honkai Beast that should have died under the oath of Mimic Judah.

The monster unleashed more black spikes, further mutilating Otto's already tattered body. His vision began to blur, and his eyelids grew heavier and heavier.

But at that very moment, Otto seemed to see the white-clad saint turn around and give him that familiar smile.

[The music reached its climax, and Otto suddenly opened his eyes.]

[“Once a person’s soul is scattered, it cannot be brought back to life.”]

Ignoring the pain, he snapped the black thorns, grasped the Void Treasury, and unleashed a burst of golden energy, completely annihilating the monster that wasn't yet fully dead.
