This is the incident that occurred to Yusuke Hirose in the chastity-reversal world before his personality changed. The event took place on his way home from his middle school graduation ceremony.
In this world, public middle schools are nominally co-ed, but boys are kept in near-total isolation. This is an unavoidable measure to protect the drastically outnumbered boys from the overwhelming number of girls driven by the impulses and desires of puberty.
During the graduation ceremony, the gymnasium was divided by a volleyball-like net—woven tightly to obscure visibility—separating boys and girls. The girls could only see the boys’ legs below the knees, yet many couldn’t resist stealing glances. Some girls near the net tried to get closer to catch the boys’ scent or pretended to drop something to peek underneath, earning reprimands from the teachers stationed nearby.
At the ceremony’s climax, students were called one by one to receive their diplomas. For the girls, this was a rare and final chance to openly admire the boys. After over 200 third-year girls finished, it was the boys’ turn. The gymnasium erupted in murmurs unfit for the solemn occasion. Despite teachers’ calls for silence—mostly female teachers, who made up 90% of the staff—some ignored the students, staring intently at the boys.
Among the mere seven boys, when the fifth, Yusuke Hirose, took the stage, the cheers reached a fever pitch. “Yusuke-kun!” “Yuu-chan!” “Hirose-senpai!” “Look this way!” “Oh my gosh, so cool!”
He was treated like an idol. It was no surprise. With his strikingly handsome face, slender build, cool demeanor, and occasional bright smile with male friends, Yusuke was deemed the most desirable boy across all grades. Girls infatuated with attractive boys formed unofficial fan clubs, and Yusuke’s was the largest, with over 100 members across the three grades—some even supporting multiple boys.
Receiving his diploma, Yusuke bowed to the stout principal, turned, and briefly glanced at the girls. His expression was neutral, but the girls’ screams grew louder. “Our eyes met!” “So dreamy! Hold me!” “Ugh, that look makes me wet!” Some blushed deeply, others shouted his name hysterically. Perhaps unnerved, Yusuke’s cheeks twitched as he hurriedly left the stage.
After the ceremony, boys and girls returned to separate school buildings, so the only chance for girls to interact with boys was during the transition. As graduates exited, boys and girls used separate entrances. The moment they left the gymnasium, the girls sprinted toward the boys’ exit, their faces desperate, overwhelming the teachers trying to stop them in sheer numbers.
This was due to a bizarre tradition among middle and high school girls: Remove a button from their uniform, ideally near the heart. Pluck a strand of hair, dip it in their blood to dye it red, and tie it tightly to the button. Give it to the boy they like, and if he accepts, their “red hair” will supposedly bind them together in the future. This baseless superstition was a desperate hope for girls vying for scarce boys. For the boys, having a blood-stained, hair-tied button forced into their hands or pockets was nothing short of horrifying, something they’d rather toss into the sky.
To Yusuke from another world, it might’ve resembled housewives storming a department store sale or obsessive idol fans. But these girls were even more frantic. Many were headed to girls-only high schools with no access to boys. Believing this was their last chance, they ran with reckless abandon. By the time the third-year girls circled half the gymnasium, the boys, sensing danger, were escorted by teachers and hired security guards to the boys’ building. The school, accustomed to this annual chaos, had tight security measures in place.
Once the boys safely entered the building, the reinforced glass entrance was locked, and burly security guards lined up in front. “Damn, we didn’t make it!” “So close!” “I just wanted to see his face up close…” The girls who missed their final chance collapsed in despair. Boys left school under guard, picked up one by one in cars, making it nearly impossible to approach them.
Among Yusuke’s graduating class was a notorious delinquent group known even at other schools. Let’s call the three leaders A, B, and C. A-ko, built like a sumo wrestler, was an invincible fighter and a city-wide infamous delinquent leader. B-ko, a black-belt karateka with a promising future, was expelled from her dojo a year ago for her sadistic tendency to brutalize peers and rival delinquents, sending many to the hospital. She then joined A-ko. C-ko, less physical but cunning, excelled at ingratiating herself with the powerful and scheming.
Their past misdeeds left them unable to get into even the lowest-tier local high schools. Facing a future as lowlife gang members under senior delinquents, they hatched a plan before graduation: not to ambush a teacher but to kidnap and assault a boy. Rape is a serious crime, punishable even at 15. However, in this world, assaulting a boy, extracting his semen, and getting pregnant could elevate their status through natural pregnancy, as artificial insemination rarely produced boys, but natural conception offered a chance. Giving birth to a boy meant substantial rewards and generous allowances, enough to live without working. Thus, targeting the school’s most handsome boy, Yusuke, was an obvious choice for their desperate bid to escape their dead-end lives.
With the help of their lackeys and recruited fan club members, the trio led a group of over 30 girls. Ignoring the post-ceremony chaos, they executed their plan, speeding off on bicycles from the school’s back gate.
“Hey, stop here,” Yusuke said suddenly, sitting in the back seat of the car, about 4–5 minutes after leaving the school’s back gate. “Huh? But…” “It’s my last day, so I want to walk a bit.” They were on a clear, straight road along a riverbank. Yusuke recalled being driven through blooming cherry trees on his first day of middle school. Today, his graduation day, he felt a touch sentimental.
The driver and accompanying women exchanged glances. They were male protection officers from a specialized agency, rigorously trained to resist impulses and protect their male charges from multiple female attackers. Their top priority was Yusuke’s safety, but fulfilling his reasonable wishes was also part of their duty.
The two officers in the front and back seats scanned the surroundings. It was a weekday morning, with sparse traffic and an empty road. Being the first to leave the school, no other students were in sight.
The lead officer in the back turned to Yusuke. “Understood. A short distance should be fine. The car will wait at the bypass road before the bridge.” “Thanks.”
Yusuke stepped out and stretched. In this world, men couldn’t walk freely alone. Even with protection officers, breathing fresh air felt liberating. The clear sky, gentle breeze, and warm sunlight signaled spring’s arrival, despite chilly mornings and evenings.
Flanked by officers at a slight distance, Yusuke began walking. The cherry tree-lined riverbank road curved left about 500 meters ahead, joining the bypass road leading to the bridge and his apartment.
A few minutes later, an elderly woman pushing a stroller gawked at Yusuke from across the street but left reluctantly upon noticing the officers. Two cars passed, likely carrying other male graduates, speeding by without stopping, to the officers’ relief. If they could reach the car without incident…
As they passed a signal-less T-junction, wild shouts erupted from the left. “It’s Yusuke-kun!” “We caught up!” “Yusuke-kun!” “Wait for us!” A group of about 10 girls from the same school, wearing “Congratulations on Graduation” ribbons on their blazers with school bags and diploma tubes in their bike baskets, sped toward them.
“Oh no!” “This is bad!” “Run!” Yusuke and the officers, faces filled with shock and fear, sprinted.
The girls, finally seeing their beloved Yusuke, pedaled furiously, closing the gap quickly.
“I’ll hold them off!” “Please!” The officer behind Yusuke grabbed a baton from her holster and turned. “No one’s getting through!” Brandishing the extended baton, she charged the speeding bike group. Swung sharply, the baton struck the two lead girls, causing them to lose balance. “Eek!” “Crap!” The following girls, unable to dodge, crashed noisily. Some tried to evade, but the officer expertly used strikes and kicks to topple their bikes. Trained in combat, she easily subdued half the group.
“You damn woman!” “Die!” Two sturdy girls from the back rammed their bikes into the officer. Their anger targeted the officer interfering with their chance at Yusuke, mixed with jealousy over her proximity to him. Despite the assault, the officer kicked one bike’s front wheel, landing a precise strike to the rider’s throat, sending her flying. She dodged the second, grabbing the basket to fling the rider off. But two girls from the rear slipped past without engaging. “Damn!” The officer reconsidered—two middle schoolers would be easily handled by the lead officer with Yusuke. Her job was to prevent the others from pursuing. In her adrenaline-fueled state, she didn’t realize these 10 were just a fraction of the group.
“Huff, huff!” “Almost there. Turn at the intersection!” The lead officer, running while checking on Yusuke, operated her radio to alert the driver of the emergency.
As they rounded the curve and reached the intersection, another wave of over 10 girls on bikes surged from the left. “Yusuke-kun!” “Wait, we’re coming!” Across the two-lane bypass, the waiting car was visible.
“Master Yusuke! I’ll hold them here. Cross the pedestrian bridge to the car!” “Okay!” Urged by the officer’s desperate expression, Yusuke ran toward the bridge 50 meters away.
As the bike group and officer prepared to clash, a group of 7–8 delinquents led by C-ko smirked from the tree line. Their plan: send two waves of fan club girls to distract the officers, drive Yusuke to the bridge, where A-ko and B-ko waited with a scooter (driven illegally) to abduct him to a nearby apartment for assault.
“Let’s go!” “Yes!” The delinquents charged.
As Yusuke climbed the bridge, seeing the delinquents behind him filled him with despair. “What the hell?! Why me?!” Though fast, his lack of regular exercise left him winded. “Damn… girls are scary… I can’t get caught…” His legs faltered, but he pressed on. The delinquents, keeping a calculated distance, grew restless seeing his back and hips—a ripe fruit ready to fall. “Yusuke-kun!” “Here we come!” “Wait!” Three athletic girls ignored C-ko’s restraint, speeding up.
The officer-driver, seeing Yusuke pursued, radioed the police and company before leaping from the car to protect him. “Hey!” “Gah!” Just before reaching the bridge stairs, A-ko’s sumo-like tackle knocked her down, followed by B-ko’s fierce kick. Even a trained officer couldn’t withstand a surprise attack from two seasoned fighters. They bound her and tossed her aside, smirking. “No more obstacles.” “Once we grab him, he’s ours.”
“Yusuke-kun, got you!” Near the stairs’ end, a girl grabbed his right shoulder from behind. “Gah!” Yusuke tried to shake her off, but she clung tightly, exhilarated by his scent. As they slowed, two others tackled his waist from both sides, one grabbing his crotch. “Eek!” “Oh!” The girl who grabbed him got a nosebleed from the sensation and fainted. Still held by the others, Yusuke stumbled forward, crashing into the bridge’s side wall and collapsing sideways. The entangled trio tumbled down the stairs.
“Hey!” A-ko and B-ko, waiting at the base, were stunned. The two girls, refusing to let go, rolled with Yusuke like a ball, not stopping at the landing and crashing into A-ko and B-ko. The two holding Yusuke fainted from the impact but didn’t release him.
“Damn it, idiots!” A-ko, recovering first due to her size, checked Yusuke and froze. Unconscious, he lay face-up, blood pooling from his head. “What do we do…?” Even with their intent to assault him, his life-threatening condition stopped them cold. As they hesitated, sirens blared, and multiple police cars arrived from across the bypass.
In a chastity-reversal world with extremely few men, a super-handsome guy like Yusuke is bound to be aggressively targeted. It could’ve been an “You’re gonna be the papa!” scenario, but a severe injury stopped it short of completion.
