What Are The Best Bakugou X Kirishima Fanfictions That Focus On Mutual Pining And Slow Burn?

Bakugou and Kirishima’s dynamic is a goldmine for slow-burn fanfics, especially when the tension is built on mutual pining. One of my absolute favorites is 'Ashes to Embers,' where the story starts with them as rivals in UA’s hero course, gradually shifting into a partnership that feels inevitable. The author nails their voices—Bakugou’s gruff exterior hiding a deep respect for Kirishima’s unyielding loyalty, and Kirishima’s admiration for Bakugou’s strength masking his own insecurities. The pacing is perfect, with small moments like shared training sessions and late-night conversations building into something electric. What makes it stand out is how it explores their vulnerabilities without losing the fiery edge that defines them.

Another gem is 'Red Riot, Blast Off,' which takes place post-graduation. Here, they’re pro heroes assigned to the same agency, and the slow burn is agonizingly good. The fic delves into their contrasting approaches to hero work—Bakugou’s relentless drive versus Kirishima’s protective instincts—and how those differences draw them closer. There’s a scene where Kirishima gets injured on a mission, and Bakugou’s reaction is so raw and visceral it’s impossible not to feel the weight of their unspoken feelings. The author does a fantastic job of balancing action with emotional depth, making every interaction charged with meaning.

For something a bit more introspective, 'Hardened Hearts' is a must-read. It’s set during their UA years, focusing on their friendship evolving into something more. The pining is subtle but constant, with Kirishima’s internal monologue revealing his growing feelings while Bakugou’s actions speak louder than words. The fic explores themes of trust and self-worth, showing how they help each other grow. There’s a particularly poignant moment where Bakugou admits he doesn’t know how to be soft, and Kirishima reassures him that he doesn’t need to be—it’s a turning point that feels earned and deeply satisfying.

If you’re into AUs, 'Crimson Sparks' is a modern-day setting where they’re college roommates. The slow burn here is delicious, with plenty of awkward moments and near-misses that keep you hooked. The author captures their chemistry perfectly, blending humor with heartfelt moments. A standout scene involves a game of truth or dare that spirals into a confession neither of them is ready for, leaving them both flustered and confused. It’s a lighter take on their relationship but still packs an emotional punch.

Lastly, 'Eclipsed' is a darker, more intense fic that explores their bond in a world where hero society is crumbling. The mutual pining is layered with angst, as they struggle to reconcile their feelings with the chaos around them. The slow burn is agonizing, with every touch and glance carrying the weight of everything left unsaid. The fic doesn’t shy away from their flaws, making their eventual coming together feel all the more real and earned. These stories all capture the essence of Bakugou and Kirishima’s relationship, blending tension, emotion, and growth in ways that keep me coming back for more.
