BellaSirin

BellaSirin is the femslash ship between Benares and Sirin from the Honkai Impact 3rd fandom.

Second Eruption
Bella, along with Avrora and Agata, was one of Sirin’s friends and fellow test subjects in the Schicksal Babylon Labs. Bella had Honkai energy injected in her, and she grabbed Sirin, screaming in pain. Sirin embraces her, telling her not to leave, but Bella’s corpse is eventually dragged away.

Once Sirin becomes the 2nd Herrscher, the Judgement class Honkai beast Benares is born and assists Sirin in her fight for revenge against Schicksal. She nicknames the dragon Bella. Both are subdued while battling Welt Yang, though Otto Apocalypse stops him before he can defeat Sirin, giving them the chance to escape to the moon.

On the moon, Sirin worries about Bella’s wounds. After meeting the Will of Honkai, she gives Bella a human form resembling the human Bella she once knew, as well as a soul. Bella referred to Sirin as her queen and served as her loyal subject, stopping the bombs Anti-Entropy launched at the moon. Bella questions Sirin’s order of monitoring the humans rather than destroying them, and Sirin explains that they have to plan around the technology humanity has and destroy them one by one.

"I came into this world as a Honkai Beast. I lacked awareness at first. There were only two things on my mind. To serve my Queen, and destroy the hated human race. I was wounded in a fight... and I used what remained of my strength to save my Queen. I thought that was the end of my life... I was given a new life. My Queen spent a great fraction of her powers to heal me. But that was not enough. She then fashioned a Pseudo-Herrscher Core... to give me a new heart. The Core granted me a human form... and a girl's soul. But it was the new name that mattered most to me. Though my enemies call me Benares, my true name is Bella, the Queen's Dragon."

- Bella's narration, Second Eruption Chapter 54.

Bella assists Sirin in her second fight against Welt Yang on the moon.

Quotes
"She has been flying ever since she woke up. Benares. Honkai Beast. Monster. The people below cried for their lives. Yet she could not hear them. She could only hear the trembles of her heart. To serve the queen. To protect the queen that calls her "Bella." She flew across the snowfield, over the mountains. Through the stars, even transcending the world we know... In the end, she fell, for she could no longer fly. When the dragon perished with her memories, in her heart, only one voice remained. 'My queen... How I wish to... be called by you once more...'"

- Kiana's narration, Chapter 17.
