Honkai: Star Rail: Handcrafting a Rider Belt Makes Me a Genius
One moment, Kaito is an exhausted office worker stumbling home after another brutal shift. The next, a truck ends his ordinary life—and a weary god offers him one last chance in a universe of his choosing.
He chooses *Honkai: Star Rail*.
His arrival point could not be worse: Herta Space Station, precisely when the Antimatter Legion launches its invasion. His only advantage is the Rider Technology Tree System, an ability that lets him unlock, study, and manufacture the technology of Kamen Riders. With the Build Driver and two Fullbottles in hand, Kaito survives his first battle and discovers that knowledge, experimentation, and combat can turn impossible fictional powers into real science.
Herta sees a fascinating research subject. Kaito sees the perfect laboratory.
Soon, the nameless outsider becomes the station's defense chief, creates intelligent machines such as Izu, and begins constructing Zea—an artificial-intelligence satellite with the potential to rival an Aeon. But every invention pushes him further beyond the future Elio foresaw. Kafka and Silver Wolf cannot read his role. The Astral Express cannot decide whether he is a genius, a menace, or both. Even familiar events on Jarilo-VI begin to fracture when Kaito starts sealing the power of the Paths inside Fullbottles.
Fate will not ignore him forever. Nanook's gaze has already brushed against his creations. Polka Kakamond is hunting the variables that threaten Nous's calculations. Duke Inferno wants the alien power he carries. Worst of all, the genes of Evolt—the planet-devouring monster from *Kamen Rider Build*—are awakening inside his body.
To survive, Kaito must build faster, grow stronger, and turn allies such as Herta, Stelle, March 7th, Dan Heng, and Bronya into a force capable of challenging the script of the universe itself.
"If destiny is only a script, then I'll build a better ending."
