Azure Waters
Bronya and Seele are two orphans who grew up together in Cocolia's Orphanage alongside Rozaliya Olenyeva, Liliya Olenyeva and Sin Mal. In January 2012, when Bronya was a child soldier, she was taken in by Cocolia after being caught on a mission to assassinate her. Seele was the first person she met at the orphanage and they were put together as roommates, becoming close since then.

Shortly after Bronya's enrolment, Seele was kidnapped but then saved by Bronya who had killed everyone there. This incident was also when the Stigmata in Seele, Veliona, had fully awoken, causing Seele to become more scared at the dark voice in her head and seemingly call Bronya a demon. Because of this, Bronya promised to never hurt anyone again for Seele's sake. However, Veliona was amused by her fighting skills.

In the following year, Bronya and Seele were reading a book together when Seele mentioned she had never seen the sea. She asked what it was like and Bronya described it as "just like Seele's eyes." They made a promise to go to the beach in the next week and that Bronya could teach her how to swim.

A couple of days before their beach visit, Sin Mal became jealous of their relationship when Seele had hugged Bronya. When Sin and Bronya were walking downstairs, she asked Bronya if she liked Seele. Unhappy with the reply "Yes. Bronya will always be with Seele", Sin pushed her down and purposefully broke her leg while Seele listened behind a wall, too afraid to help. Bronya returned to their room later to be met with Seele hiding in their toy chest, crying and continuously apologising. She threw her crutches to the side to lick Seele's tears away and hug her, with the words "It's alright, Seele. I don't feel the pain as long as you're here with me." That same night, Seele couldn't sleep and gave into Veliona's voice in her head that told her she could get revenge on Sin to keep Bronya safe. She met Sin in the hallway where Veliona soon took control and tortured her till she passed out.

When Seele found out about the life-threatening X-10 experiment, she demanded that Cocolia let her take Bronya's place as a test subject to keep her safe. The experiment was going well until Seele vanished and Veliona took control to let her see Bronya for one last time. She reappeared outside the labs with a scythe and when she got to the orphanage to see Bronya, her body started fading and she finally reduced to a quantum state with no way of being able to be brought back. Bronya was left in their room holding a hairpin she had left behind, crying. When Cocolia came back, Bronya threatened to take her own life if she didn't let her also take part in the experiment to see Seele. Cocolia had no choice but to let her.

In the Quantum sea, the two saw each other and Bronya refused to leave, holding onto Seele who was also crying. Seele was worried and didn't want Bronya to also disappear, but Bronya said she was what mattered most to her, not the test or the real world. Seele eventually convinced her, and they made a promise that they would see each other again. Bronya would look for a way to bring her back and never give up while Seele would wait for her as long as it takes. Before leaving, Seele gifted Bronya with the robot Project Bunny 19c, who became Bronya's main weapon, and kissed her. "I gave you my first kiss, Bronya! You'll have to kiss me back when you return to take me home." When Bronya returned to the real world, she had lost the ability to feel high order emotions and the ability of her legs.

Main Story
Since then, Bronya met Kiana and Mei and enrolled in St. Freya High with them. Though she was content, Bronya never forgot her promise and longed to reunite with Seele again.

Under the Deep
Bronya goes to the Quantum Sea through the Eye of the Deep in order to retrieve the Gem of Desire. As part of Joachim's trials for entering deeper into the Sea, Bronya is transported to an alternate bubble universe as a student of a different St. Freya, where Cocolia is her teacher. Bronya is assigned a mission, shocked to see that one of her teammates is Seele. Seele looks taken aback, curiously looking at Bronya, then introduces herself. Bronya is disappointed to see that this Seele doesn't know her but berates herself for expecting anything else.

As they work together, Bronya notices that this Seele seems to know everything about the mission, easily identifying where the stolen assets are being hidden. The team finds out that this "asset" is a young boy, Joachim, who is the 1st Herrscher. Bronya and Seele are tasked to evacuate Joachim, but Seele tells Bronya that they mustn't leave him to Schicksal, or they will end up where they started, again and again. In face of Bronya's hesitation, Veliona takes control and summons a Quantum Shadow, which Bronya defeats. Seele, knowing it is impossible for people of this world to defeat a Quantum Shadow, widens her eyes in realization. Bronya, noting Seele's weird behavior from the start, also realizes that this Seele is the one from her world. They embrace with tears in their eyes, elated to have finally found each other.

After their reunion, Seele explains that in an effort to find Bronya, she opened a door and found herself in this bubble universe. Whether or not she failed or succeeded the mission, Seele was caught in a time loop. Bronya comforts Seele and tells her she knows what to do now. Bronya tells Cocolia that they can't send Joachim back to HQ because he is being subject to inhumane experiments; rather, they should enroll him in St. Freya and give him a choice over his destiny. Cocolia agrees, and Seele is shocked and relieved that the world didn't reset again. Passing Joachim's trial, Bronya is sent back in the Quantum Sea but only with Seele's journal. She asks Joachim about Seele. He explains that Seele has a unique ability to drift across the Sea, so perhaps that was a fragment of her. Seele's journal, however, can serve as a link between them and guide her. Bronya holds the journal close, telling Seele to wait for her. Honkai: Star Rail=

Fanon
Bronseele is one of the most popular ships within the Honkai Impact 3rd fandom, especially considering that mutual feelings are apparent. The Veliona and Bronya ship also falls under Bronseele, because Seele and Veliona are the same person, though the ship mostly pertains Seele. Due to the announcement of the game Honkai: Star Rail, a new game in the Honkai series, Bronseele's popularity has increased even more since both of the characters are present in the game and have a lot of interactions together. It gave Bronseele a new backstory which gave the relationship a new layer.
