Honkai: Star Rail: From the Start, I Use Villains as Blood Bags

[Honkai: Star Rail fan fiction + two male leads + yandere obsession + ultimate redemption + intense mutual devotion]

Jiang Ci is transported into a Stellaron Hunters base, where he’s greeted with late-stage Mara-Struck and a thirty-minute countdown to death. Outside the door is Blade, completely out of control and killing everyone in sight. To survive, Jiang Ci awakens the “Pain Transposition Furnace.” Instead of backing away, he throws his arms around the frenzied Blade and cries, “I’ll take your Mara-Struck! I’ll take your pain!”

When the incantation fails, when the Mara-Struck is devoured, when a black-flame greatsword powerful enough to destroy a star system shatters the IPC fleet, every Stellaron Hunter is left dumbfounded. Jiang Ci not only survives, he turns every terminal illness, every contamination, and every curse in the universe into fuel to keep himself alive.

Blade discovers that as long as Jiang Ci is by his side, the grudges and Mara-Struck that have tormented him for a century finally subside. From then on, the galaxy has a new walking, talking “painkiller,” while the swordsman who once wished only for death has a mad, possessive gleam in his eyes. “Want to touch him? You’ll have to get past my sword!”
