Action Fan Reborn: Yandere's Pursuit!

When action movie junkie Philipe finds himself reincarnated as Ryujin, the designated punching bag for the hero's experience points in a web novel he's never read, the story quickly morphs into a rollicking ride of unforeseen twists. Oblivious to the original plot, Ryujin inadvertently spins the narrative on its head.

The heroine, who was scripted to double-cross and slay him, now owes him a life debt. The adoptive sister, originally penned to loathe him, is head over heels in love with his character and has morphed into a hilarious, over-the-top Yandere. Meanwhile, Pedro, who is on a mission to steer Ryujin back to his villainous path, faces repeated disappointment. Ryujin, after all, is more interested in doing push-ups than causing mayhem. Welcome to the most absurdly delightful misinterpretation of a villain's life.
