My Only Bitchy Cousin Is a Yankee-Type Guy! The Rival Appears!

Summer fades, fall begins, and Shinichi’s quiet life with cousin Rio takes a wild turn. Enter Kaoru Daidouji’s daughter—a bold rival claiming the “strongest in town” title. With brags, bluffs, and a dash of teasing, the trio’s summer-ending showdown is anything but ordinary.

About:

Summer is over and it's almost autumn.

The main protagonist Shinichi and his cousin Rio have decided to live together for various reasons.

A Otokonoko named Daidouji Kaoru appears before the two of them.

Kaoru tells Rio that he will duel with him for the title of the most beautiful man in the town, which will definitely be a dirty duel.

Rio readily agrees, saying it would be a good way to kill time.

Kaoru boasts that he has never missed masturbating four times a day, but it seems that he has never had any sexual experience before.

"I'll make you understand that I'm more beautiful than you!

Of course, with my body♪"

Rio says this with a mischievous smile.

Seasonal Shifts and Unwelcome Guests: When Summer Ends, Chaos Begins

The Calm Before the Storm: Post-summer, Shinichi and Rio settle into their shared home—routine, relaxed, and quietly familiar. That is, until a new face arrives: Kaoru, daughter of the elusive Mr. Daidouji. Her sudden appearance shakes up their calm, announcing a “strongest in town” duel. “Bet you can’t beat me,” she smirks, setting the stage for a battle of wits (and pride).

Rivalry 101: Bragging Rights on the Line: Kaoru’s confidence is unmatched. “I’ve never missed a day of… personal time,” she quips, dropping hints about her habits with a straight face. Shinichi, ever the skeptic, fires back: “Strength isn’t just about… that.” But beneath the banter? A spark of genuine competition—and maybe a little insecurity.

Rio’s Role: The Prankster Bystander: Never one to stay quiet, Rio laughs at Kaoru’s boldness. “You’re way too cocky,” she teases, egging on the duel. Is she team Shinichi… or just enjoying the show? Her laughter hides a hint of something sharper—maybe a desire to prove herself, too.

The “Strongest” Game: Rules, Bluffs, and Unspoken Tensions

What Counts as “Strongest”?: The duel’s rules are fuzzy. Physical strength? Mental grit? Kaoru insists it’s “all about confidence”—her go-to line when pressed. Shinichi, practical, suggests a test: “Who can fix the broken motorcycle faster?” Rio chimes in, “Or who can eat the spiciest ramen without crying.” The real question? Who’s willing to bend the rules to win.

Kaoru’s Secret: Bravado or Experience?: Her “never missed a day” comment raises eyebrows. Is she being honest… or fishing for reactions? Shinichi suspects she’s hiding something—maybe a past loss, or a fear of failing. When he presses, she deflects: “Prove me wrong if you can.” The tension thickens.

Rio’s Hidden Agenda: Her teasing feels playful, but there’s more. She slips hints about Kaoru’s “reputation”—how she’s “too loud,” “too bold,” “too much.” Is Rio jealous? Or does she see through Kaoru’s act, sensing the vulnerability beneath? Her motives add a layer of complexity to the rivalry.

The Stakes: Pride, Rivalry, or Something Deeper?

Winning vs. Losing Face: For Kaoru, losing isn’t just about pride—it’s about proving she’s more than her father’s shadow. For Shinichi, it’s about protecting his spot as Rio’s “partner in crime.” Rio? She just wants to see who cracks first. But as the duel heats up, the stakes shift: suddenly, it’s not just about who’s strongest… but who’s real.

Moments That Matter: Small interactions reveal character. Kaoru hesitates when Shinichi mentions her “personal time” habit. Rio softens when Kaoru admits she’s nervous. Shinichi laughs, unexpected, at one of Rio’s jokes. These moments humanize the rivalry, turning it from a battle into a story about connection.

The Unseen Force: Who is Kaoru’s father, and why’s he absent? His absence looms large—does he have a hand in the duel? A hidden motive? As the trio digs deeper, they uncover clues that tie Kaoru’s bravado to a past she’s desperate to escape.
