Not everyone can see the darkness of this world.
And not all can reach the true limits of the martial arts.
Long ago, the San'iku Foundation initiated a secret project-one that sought a path to martial power beyond human limits. Under the guise of "Extraordinary Ability Breakthrough Research," they launched a program called The Gate Project.
The so-called "Otherworld" is the product of this endeavor.
A supernatural dimension - a realm that exists between reality and the unknown.
Using special devices, the Foundation forced open the "Gates" and sent hand-picked prodigies into this dimension, where only under extreme conditions could they transcend their limits.
But the project was far more terrifying than anyone could have imagined...
Some who went never returned. Others returned as broken minds, driven mad.
And few returned as Otherworld Walkers, wielding powers never before seen.
Black Blade was the first to come back alive.
But he... was not the only one.
Act I: The Defeat of Black Blade Rain poured down like a curtain. Storm clouds swallowed the sky.
On that day, Black Blade once again passed through the Otherworld Gate and returned to the land of Tokigumo Academy with the title of "Walker.
His body was no longer the same as it had been three years ago, shrouded in a dark aura, his eyes burning with deep purple-black lightning.
He announced with royal arrogance:
"Tendou Kyouichi... face me."
A challenge to an old comrade to prove that he was no longer the man he once was.
But the result of their duel defied all expectations - three moves.
Only three.
Tendou Kyouichi needed only three strikes to defeat Black Blade!
The first strike shattered his illusionary clone.
The second shattered his otherworldly energy shield.
The third landed squarely on him, slamming him into the ground like a fallen meteor.
The entire Academy shook.
All who watched gasped in disbelief.
But even as he lay defeated, Black Blade smiled - eerily, knowingly.
"...So I'm still not strong enough, huh?"
Immediately, agents of the San'iku Foundation appeared, took the wounded Black Blade away, and imprisoned him in the organization's secret facility - the Correctional Prison.
Act II: The Prison of Hell
When Black Blade awoke, he found himself surrounded by cold steel walls.
This was the Correctional Prison of the San'iku Foundation—a facility used to "reform" failed test subjects. And he was now slated for a new program:
First Phase Augmentation Training.
Pain was his instructor.Blood was his textbook.
"Surpass humanity, or die."These words were carved into the wall like a death sentence.
Day after day, he was pushed to the brink—his body forcefully injected with "Otherworld Enhancement Factors," increasing his strength, speed, and perception. But in exchange, he endured mind-shredding agony.
Yet he never broke.
He endured the tearing of muscle, the shattering of bone, the searing of nerves...
Until one night, he slowly opened his eyes.
The violet-black lightning burned fiercer than ever before.
"...Almost there.""Now, I'm strong enough to kill anyone in my way."
Black Blade had evolved.
Act III: Invasion of the Otherworld Walkers
Meanwhile, outside Tokigumo Academy, a new battle erupted.
The main cast faced a terrifying threat—Otherworld Iron Fist.
Another who had returned from the Otherworld, his former name long erased. Now, he was known only by this title.His body had been grotesquely enhanced—muscles swelled, his height towering nearly twice that of a normal human, and both fists burned with blue-gold energy ripples.
[Iron Fist – Character Profile]
Abilities (Phase One): Strength + Psychic-type Hybrid(Brutal physical power combined with mental interference.)
Trait:Every time his fists strike the ground, they generate a "Shockwave Field," causing a brief mental delay in opponents—like being struck at the back of the skull.
Combat Style:Blends raw power with high-frequency vibration attacks, resulting in devastating force.
His opponents: Yorumi Sou, Hakuran, Gouzanjirou Retsu, and Mitou Karuma.
"Brats, think you can challenge me?"Iron Fist roared with laughter as he swung, his fist tearing up the earth—stones crumbled like sand!
The shockwave tore through the battlefield, warping the air itself.Even as they dodged, the group felt the aftershock—brief lapses in reaction time, like their minds were momentarily stunned.
"Damn… his shockwaves mess with our perception too?!"Hakuran cursed.
Iron Fist sneered:"You half-baked warriors are nothing. The ones who survive the Otherworld… are monsters beyond reason!"
He hurled another blow—this time straight at Yorumi Sou!
"Die, kid!"
Yorumi's eyes widened, flipping a magic card to summon an illusion array—but—
The sheer impact blasted him back several meters!
(Yorumi: "Damn… this guy's strength is unreal…!")
The Walkers from the Otherworld—They were on a whole different level.
This time, our heroes face a threat unlike anything before.
Back in the darkness of his prison, Black Blade slowly raised his head, his gaze sharp and unreadable.
He was no longer the man of three years ago.
Now he was more terrifying than the Otherworld itself.
"Just wait, Tokigumo Academy."
"When I break free... I will challenge every single Otherworld Walker."
His ultimate goal - Tendou Kyouichi. Yorumi Sou.
引言:异界空间的起源
世界的黑暗,并非所有人都能察觉.
武者的极限,也绝非所有人都能触及.
很久以前,圣育财团成立了一项秘密计划,旨在寻找"超越常规"的武道之路.他们在全球范围内挑选最顶尖的天才,并以**"异能突破研究"**的名义,开展了一项名为——
"界门计划".
所谓的"异界空间",便是这个计划的产物.它是一个超自然维度,是"现实"和"未知"交界的领域.财团通过特殊装置打开"界门",让选中的天才们进入其中,在极端环境中突破自我.
但这项计划远比想象中可怕...
进入者之中,有些人再也没有回来,有些人归来时已变成疯子,而有极少数人——以"异界行者"的身份,获得了新的力量.
黑神刃,便是第一个活着归来的人.
但他,并非唯一的归来者...
[第一幕:黑神刃的败北]
暴雨如注,乌云压城.
那一天,黑神刃跨越了异界空间的门扉,带着"归来者"的名号,重新踏足东云学园的土地.他的身体已不同于三年前——暗黑气息缭绕,眼瞳之中燃烧着深邃的紫黑色雷光.
他以王者之姿宣布:
"天道京一,来战."
——他要向旧日的故友挑战,以证明自己已非昔日之人!
然而,决斗的结局,却远超所有人的想象...
三招,仅仅三招.
天道京一仅用三剑,便将黑神刃击溃!
第一剑,斩碎了黑神刃的幻影!
第二剑,破灭了黑神刃的异能屏障!
第三剑,直击黑神刃的躯体,将他狠狠钉入地面!
整个东云学园为之震撼.
所有观战者无不倒吸一口冷气.
但黑神刃却在倒地的瞬间,露出了诡异的笑容——
"...原来,我还不够强啊."
随即,圣育财团的特工部队迅速出动,将重伤的黑神刃带走,并秘密送入财团内部的**"修正监狱"**.
[第二幕:监狱炼狱]
黑神刃醒来的时候,眼前是幽暗的钢铁墙壁.
这里是圣育财团的"修正监狱",一座专门用于"改造失败实验体"的地方.而他,即将成为"改造"计划的一部分——第一形态强化训练.
疼痛,是他的导师.
鲜血,是他的教科书.
"要么超越人类,要么死."
这句话刻在监狱的墙壁上,像是一道死亡判决书.
每一天,黑神刃都被逼入极限,他的身体被强行注入"异界强化因子",让他的力量,速度,感知等全面提升,但代价是——极度痛苦的撕裂感.
但他没有屈服.
他咬牙承受,忍耐着血肉的崩裂,骨骼的断裂,神经的灼烧...
然后,在某一天夜里,他缓缓睁开双眼.
紫黑色的雷光,比从前更加猛烈.
"...差不多了."
"现在的我,已经足够杀光所有挡路的人."
黑神刃,进化了.
[第三幕:东云学院外,异界行者的入侵]
与此同时,东云学园的外围,一场激战正在上演.
主角团正围攻一个可怕的存在——"异界铁拳".
这是另一个从"异界空间"归来的强者,他的本名早已被遗忘,如今只剩下这一个称号.他的身体被某种异界力量改造,筋肉膨胀,体型比普通人高出整整一倍,双拳之上燃烧着蓝金色的能量波纹.
[异界铁拳·设定]
异能第一形态: 力量系+精神系（拥有恐怖的破坏力,并且能影响对手的精神状态）
特性: 每当拳头轰击大地时,都会产生"冲击波场域",导致敌人的意识产生短暂的迟滞感,仿佛被重击后脑一般!
格斗风格: 结合蛮力与高频震荡波,拥有惊人的破坏力.
他的对手,是夜见苍,白蓝,豪战寺烈,御堂狩真四人.
"小鬼们,敢挑战我?"
异界铁拳狂笑,猛然挥拳,拳风直接掀飞大地,连岩石都被震碎!
狂暴的冲击波席卷战场,空气仿佛在震荡,夜见苍等人纷纷闪避,但即便如此,意识仍旧受到轻微冲击,速度与反应力出现短暂的迟滞!
"可恶...他的冲击波还能干扰精神?!"
白蓝咬牙低喝.
异界铁拳冷笑:"比起你们这些半吊子的能力者,真正活着走出'异界空间'的人,才是无可匹敌的怪物!"
他再次出拳,这一次,目标直指夜见苍!
"死吧,小子!"
夜见苍瞳孔一缩,立刻翻转手中的魔术卡牌,激活幻术阵,然而——
他的身体竟然被硬生生地震退数步!
（夜见苍:糟糕...这家伙的力量太离谱了...!）
异界行者的力量,超乎想象.
这一次,夜见苍等人真的遇上了前所未有的劲敌.
[第四幕:黑神刃的觉醒]
画面再度切回监狱.
黑神刃在无尽的黑暗之中,缓缓抬起头,目光深邃.
他已不再是三年前的他.
现在的他,比异界更可怕.
"...等着吧,东云学园."
"等我出狱的那一天,我要挑战所有异能行者."
最终目标——
天道京一,夜见苍.
