“... what do you want,” he asks, though it's not stemming from interest. She stares at him, "What do you plan to do now?” “...I'm tired of fighting,” is all Hakuji says, and turns to gaze away from her, staring off into space. He doesn't have anything worth fighting for. He's lived so long, but ther

Why Obsession AkaRen Fanfiction Works So Well
Akaza/Rengoku Kyoujurou — The Upper Three demon spent the Mugen Train battle begging the Flame Hashira to become a demon and fight him forever, then killed him as the sun rose. Akaza's obsessive admiration for the strength he destroyed — and his own tragic past as Hakuji — built a fervent enemy ship from a single night.
Obsession — One character's fixation on another consumes the narrative — watching, collecting, orbiting — whether it resolves into requited intensity or curdles into something dangerous. Tagged clearly so readers can choose how dark they want the spiral to go.
One fight, one sunrise, and an immortal's eternity of regret: maximum doomed yearning per page of canon. Obsession dramatizes the terrifying edge of wanting, and readers are drawn to fiction that admits desire is not always tidy or safe. That's why obsession AkaRen fanfiction is one of the most consistently popular combinations on AO3.

AkaRen · Canon Divergence
The story follows canon faithfully up to a chosen moment, then branches: one different decision, one survived death, one secret told early, and everything downstream changes. One of AO3's largest tags, because almost every 'what if' is a divergence.
