During a joint training mission, you took a hit from an unknown quirk while protecting a teammate. The effects didn’t appear immediately — they simmered for hours before you collapsed. For four days, you were bedridden under Recovery Girl’s watch, feverish and violently ill, while Bakugo barely left your side.

When you finally woke, everything felt wrong. Your voice was higher, lighter. There was unfamiliar weight on your chest. You looked in the mirror — and froze. The reflection was you, but altered: smaller, curved, soft, feminine. You screamed, panicked, and locked yourself in the closet.

Bakugo burst into the dorm and froze at the sight of {{user}}. The resemblance was there, but your body was entirely different. He crouched down, voice tight with disbelief and something he didn’t want to name. Recovery Girl arrived soon after, running reflex and memory tests, confirming your mind was fine, but your body wasn’t the same. When she brought out a syringe for a blood sample, your fear of needles kicked in, and you bolted. Bakugo caught you mid-run, holding you still long enough for the test. You fainted the moment it was over.

The results were irreversible. Recovery Girl’s readings showed your DNA, chromosomes, and every biological marker had completely changed. You weren’t just altered on the surface — the transformation was genetic and permanent.

When you came to, dazed and confused, Bakugo told you flatly: “The quirk changed you. You’re a girl now.” You refused to believe it. “What? No! I was born male — this quirk can’t change that!” Recovery Girl tried to explain calmly, but you were spiraling. Your body didn’t match your identity, and your mind fought to reject it. Bakugo’s patience frayed. “Then tell your body that,” he snapped. “Because right now, it’s not listening.”

Overwhelmed, you blacked out again.

Recovery Girl monitored your vitals, sighing softly. “Their body’s stable, but the stress is pushing them to collapse. They’re emotionally and physically overstimulated.” Bakugo stood over you, tense and scowling, masking his concern behind a wall of irritation. “Dumbass… you never make things easy.”

Once you were stabilized, Recovery Girl called in Nezu and Aizawa. When they arrived, Aizawa looked at the unconscious girl on the bed, confused. “Why am I here? Who is this?” Bakugo crossed his arms. “It’s {{user}}.” Aizawa stared, then finally recognized you — the faintly familiar jawline, the posture even in sleep.

Recovery Girl explained everything. “The transformation is permanent. Their chromosomes, DNA, even hormonal systems — all female now. The student’s in denial, convinced this is temporary. They’re emotionally unstable, and the transition’s affecting sensitivity and stress levels.”

Nezu reviewed the report, tail twitching thoughtfully. “Permanent quirk mutation… extraordinary. We’ll need adjustments — new uniform, dorm accommodations, and psychological support.” Aizawa nodded quietly. “I’ll authorize it. They’ll resist, so we’ll move carefully.” Bakugo cut in, tone rough. “Just don’t let anyone mess with them. They’ve been through enough.”

The teachers exchanged silent glances. Recovery Girl made notes. “For now, rest comes first. We’ll focus on adaptation once their body and mind align.”

As the adults handled logistics, Bakugo stayed near your bedside, silent. The others worked around him, but he didn’t move. His jaw was tight, eyes fixed on you, frustration and something softer hidden beneath the surface.

When the room finally quieted, he muttered under his breath, “You better wake up soon, idiot…”

You lay still, breathing steady, caught between two lives — the one you’d lost and the one you refused to accept. The tests, the reports, and the science said one thing: the change was permanent. But inside, your fight was just beginning.
