Seishironagi Stories

For everyone who has ever loved quietly. For the dreams we had to let go of... ...and for the people who taught us that life could still be beautiful afterwards. "Some stories begin with a confession. Ours began with a heartbeat that refused to keep up."

But when your secret obsession with all things bear (stuffed bears, bear hoodies, bear doodles, you name it) mixes with your love for volleyball, you were sure your world was set far away from football. That is, until "Rin" casually throws you into the infamous Blue Lock group chat. Now you're stuck between sharp-tongued strikers, your cold older brother, and a dozen egos bigger than a bear paw.

Here's my second fanfic Blue Lock Chapter , where both of Bachira's and Nagi's "abilities" are pushed to their absolute , logical limit (atleast in my opinion) . Since I had so much fun writing the first one , I decided to make another one . I know these don't have an audience (yet ?) but if you like them , don't hesitate to share ! If you read the previous one and plan to read this one , let me know which one's your favorite ! Cover is made by AI , for illustrative and entertainment purposes Original work by Muneyuki Kaneshiro and Yusuke Nomura

"maybe... you're not a hassle after all." in which nagi might've found someone other than reo that isn't a pain.

❝ I don't wanna play soccer right now... so I'm kind of avoiding Reo. I didn't know where to go, so I'm here. ❞ A story where you find yourself becoming partners with a guy you barely knew for a math project. You tell yourself you'll just put up with him and his lazy demeanor up until the project is over. That's until you realize you want to end up becoming more than just partners. !fem x nagi seishiro

☆⋆｡𖦹°‧★ Y/N's whole worlds is the volleyball court - early mornings, bruised knees, and the adrenaline she gets whenever in a match While Nagi is just, well Nagi. He thinks everything's a hassle. Nagi has fangirls pestering him every second, Y/N isn't as popular but she definitely has confessions once a month. Even being literal polar opposites, Y/N and Nagi have been close friends since childhood. Though during high school, their bond grows into something much more than just friends.

➽ 𝐁𝐋𝐋𝐊 𝐗 𝐑𝐞𝐚𝐝𝐞𝐫 ╰─▸𝑶𝑻𝑶𝑴𝑬 𝑨𝑼! You were just a college student ordinary, invisible, surviving exams and heartbreaks. Until one night, after binging an otome game where you played the cunning Villain/ness doomed to fall, you passed out with the screen still glowing. When you opened your eyes, it wasn't your ceiling you saw. It was a chandelier. And a ballroom. Silk gloves on your hands. A porcelain teacup poised in your grip. Across from you? One of the male leads, watching you like a hawk like you were the threat the story warned him about. You weren't just playing the antagonist anymore. You'd become the antagonist themselves. And in this world, villains don't always get a second chance, but they do get to rewrite the game.
