Find out in this My hero Academia fan fiction called "Duet: A story of love and loss."

Title: Duet: A Harmony in Heroism Chapter 1: The Hive Heart Misaki was always one to stand out in a crowd. Born with the quirk "Duet," her unique appearance of two identical heads and four arms was a sight to behold. As she grew older, she discovered another aspect of her extraordinary quirk – she could duplicate herself like a cellular division, each clone sharing her unique appearance and a hive mindscape. Despite the cool sides to her power, there was a downfall: the more she duplicated herself, the higher the taxation on her stamina and concentration. With five being her safe limit, she had once stretched her boundaries to eight - at a hefty cost. When she found herself accepted into UA, Misaki had vowed never to push to such reckless lengths again. That was easier said than done when she ended up in the same class as Syouma, the boy who had her heart pulsating faster than any rhythmic beat. Chapter 2: The Prelude When Misaki was paired with Syouma upon their first mission, her heightened nerves only amplified. Syouma, perhaps sensing her anxiety, offered her a warm, earth-breaking smile that shattered her heart into a million fluttering pieces. As they delved into their mission, Syouma admired her unique quirk and subtly confessed his growing attraction towards her, knit with respect and a blooming affection. Their tranquil bonding was brusquely interrupted when the building they were in shuddered dangerously and Syouma was pinned under a heap of heavy debris. Chapter 3: Harmony or Discord Misaki's heart pounded erratically against her ribcage as she surveyed the situation. She didn't need the conventional method of holding a mirror to herself to see the fear mirrored in both her faces. Syouma was trapped, and he needed her help. Collecting her wits, she set her jaw in determination. Two, three, and then four - her replicants made their appearance, each one's facial expression a mirror of her own. They worked in unison, their four arms hefting the rubble that trapped Syouma. Minutes passed agonizingly slow, and it was clear she had to redouble her efforts. Chapter 4: Crescendo Remembering her previous extreme of eight, Misaki steeled herself, trusting her training and the insurmountable determination surging within her. Without a backward glance, she strained and focused, reproducing a total of ten duplicates. She could feel her strength ebbing, her concentration a tenuous thread threatening to rupture at any moment. But she pushed on, her clones working tirelessly to free Syouma. The strain was tremendous, her physical and mental capacities pushed beyond what she ever thought possible - but with a triumphant shout from her many mouths, Syouma was free. Epilogue: Duet’s Grand Finale As her numerous bodies morphed back into one, Misaki collapsed from exhaustion but managed to catch a final glimpse of Syouma, safe and thankfully unhurt. His eyes were on her, brimming with gratefulness and newfound respect, his words echoing in her dually ringing ears, “You're beyond amazing, Misaki.” Later on, in the safety of the hospital, Misaki realized her capabilities knew no bounds, that she could break her limits when pushed. She recognized that she was stronger than she had ever given herself credit for, and that falling in love could indeed make a person do strange things. Most importantly, she understood that her "Duet" quirk was a blessing in disguise, a duet of strength and courage that characterized her as an evolving hero. But for the moment, Misaki was content just being a teenage girl in love, looking forward to her next mission with Syouma and excited for her journey towards becoming the hero she was destined to be. She was Misaki, and she was duet, beautifully unique.
