第1章：尼布尔海姆的怪力小子

Nibelheim's Monster Boy

When the blood of the magic swordsman Sparta spread to a planet without the hero Claude, the trajectory of fate was completely rewritten.

Kain, Vergil's descendant left behind in another world, was adopted by a kind woman from Nibelheim and formed a childhood sweetheart with Tifa. However, demon blood is both a gift and a curse. To protect his beloved, he awakened in flames, only to fall prey to Shinra's inhumane experiments.

Inheriting the legacy and destructive sword of the hero Zack, he arrives in Midgar with his memory clouded. Here, he connects with the soul of the destined flower girl Alice, befriends the lively ninja Yuffie, and even attracts the morbid yet passionate love of Queen Scarlet of Shinra.

With his mortal body, he rewrites tragedy time and again; with the power of a demon, he strikes back against fate. From Midgar to the Great Hollow, he slashes through despair and protects every bit of warmth around him. When the wings of light of the True Demon unfold, he will wield the ultimate secret, the fusion of all bonds, and personally "slay the gods."

This is the story of a lost demon boy who searches for a home in the world of Final Fantasy, protects his family, and ultimately becomes a legend. However, when the dimension-severing blade, [Yanma Blade], awakens within his soul, he and his family face an even more magnificent, world-spanning epic.

当魔剑士斯巴达的血脉，流落在没有英雄克劳德的星球之上，命运的轨迹便已彻底改写。

凯因，维吉尔遗落在异世的后代，被尼布尔海姆的善良妇人收养，与蒂法结下青梅竹马之缘。然而，魔人血脉既是天赋，亦是诅咒。为守护挚爱，他在烈焰中觉醒，却也因此坠入神罗的非人道实验。

继承英雄扎克斯的遗志与破坏剑，记忆混乱的他来到米德加。在这里，他与命运的卖花女爱丽丝灵魂共鸣，与活泼的忍者尤菲不打不相识，更引来了神罗女王斯卡雷特病态而炽热的爱恋。

他以凡人之躯，一次次改写悲剧；凭魔人之力，向宿命挥剑。从米德加到大空洞，他斩断绝望，守护着身边的每一份温暖。当【真·魔人】的光翼展开，他将以融合了所有羁绊的最终奥义，亲手“弑神”。

这是一个遗落魔子，在最终幻想世界中寻找归宿，守护家人，并最终成为传奇的故事。然而，当那柄能斩断次元的【阎魔刀】于灵魂深处觉醒时，他与他的家人们，将要面对的，是更加波澜壮阔的，跨越世界的全新史诗。
