Echizen's Big Sister Is Anything but Detective Fiction

Yue Qian Naie, manager of Rikkai University's tennis club, is a name that strikes fear into everyone's heart.

On his first day at school, the brash newcomer Kirihara declares that he'll defeat the Big Three and become the tennis club's No. 1.

The dream is beautiful, but reality is cruel.

Before he can even get started, Yue Qian Naie knocks him flat.

Staring at the tennis ball smashed to pieces, Kirihara's whole worldview is shaken: "...Can a human really hit a ball like that?"

To promote the tennis club members' physical and mental well-being, Yue Qian Naie rewrites their training schedule, multiplying the workload by N. Her motto: If it won't kill you, train until it does.

The result is a tennis court full of corpses.

A passing student is horrified: Have aliens invaded Earth?

To fire up the club members, Yue Qian Naie makes a special drink and gives it an embarrassing name: Sweet, Sticky, Gooey, Gulp-and-Splutter Tea.

The regulars, acting like spoiled brats: "Sweet... sticky... what kind of tea?"

Who can remember a name that long?!

At first, some people scoff at the special drink, thinking it's just an ordinary beverage.

That is, until the first unlucky soul rolls his eyes back and collapses. Only then do they realize how serious things are.

Seeing Yue Qian Naie smile ominously, the regulars swallow nervously. "Don't come any closer!"

And so, the tennis court is "littered with bodies" that day.

One day, Yue Qian Naie meets Inui from Seishun Academy. The two hit it off immediately and eagerly discuss the recipe for their special drink.

The members of both tennis clubs go numb with dread, unable to see a future.

Only Fuji smiles. "This looks like fun."

By every measure, Yue Qian Naie is described as an extraordinary girl. (Meaning she has an astonishing amount of strength.)

When she's taken hostage by criminals, Yue Qian Naie keeps her cool and punches them flying. They say the criminals spent half a month in the hospital.

Facing the police officers' horrified stares, Yue Qian Naie looks innocent. "I'm just an ordinary middle school student."

Ryoma, who saw his older sister crush a tennis ball: "..."

Amuro, who saw her dodge bullets with his own eyes: "..."

Matsuda, who saw Yue Qian Naie carry a truck: "..."

Everyone: "...Are you sure you understand what 'ordinary' means?"

How are you ordinary at all?!

Yue Qian Naie thought her life would pass by uneventfully, until one day she stumbled upon a criminal organization committing murder. Caught off guard, she was knocked unconscious with a club and poisoned.

The good news: She didn't die.

The bad news: She shrank down to the size of an elementary school student.

Yue Qian Naie: Eyes wide with shock.

--- Upcoming Story ---

Hanasawa Rio transmigrates into a melodramatic Prince of Tennis fanfic as the villainous female lead, and happens to be Sanada's cousin.

In the novel, Hanasawa Rio is a scheming green tea who will stop at nothing to win the male lead's heart. She acts kind and innocent on the surface, but secretly frames the heroine and sabotages her relationships with the male leads. In the end, her true colors are exposed and she meets a tragic fate.

She has to complete the plot before she can go home.

Scene One: Humiliate the heroine and threaten her into leaving Rikkai University.

Hanasawa Rio marches over to the heroine and slaps a check down on the table. "Here's five million. Leave Rikkai University!"

System: "?"

Heroine: "?"

Using money to humiliate someone still counts as humiliation.

Scene Two: Frame the heroine and make the male leads hate her.

Hanasawa Rio pretends the heroine pushed her into a river, then falls in and cries for help.

Yukimura rushes over and sees the water only reaches her chest: "..."

The System is exasperated. "Couldn't you have picked a deeper river?!"

Hanasawa Rio looks innocent. "But I can't swim. What if no one gets here in time and I drown?"

System: That's a good point. I can't argue with that.

Scene Three: Cling to the male leads and win their affection, only to be despised when the truth comes out.

Hanasawa Rio applies to be manager of the tennis club, ready to show off her skills, but nearly hits Yukimura in the head with a tennis ball.

For Atobe's birthday, Hanasawa Rio bakes a cake herself, but uses the wrong ingredients. Atobe rushes to the bathroom and throws up, questioning his entire existence.

During Niou's training, Hanasawa Rio brings him water, but accidentally gives him Yanagi's juice instead. Niou dies on the spot.

*

After witnessing tennis players use superpowers, Hanasawa Rio's worldview is shattered. The System tells her she's transmigrated into a tennis anime, and she becomes convinced that only someone with great tennis skills can be the protagonist.

When she meets the handsome, popular Kise, she has no interest. "You could be amazing at basketball and still never be the protagonist."

When she meets Dazai, who believes he's taken on the mission of saving the world, she dismisses him. "You don't even play tennis. How could you be the protagonist?"

Seeing Chuuya's gravity powers overpower everyone, she sighs. "What a shame. You can't play tennis, so it doesn't matter how strong your ability is."

Everyone is baffled: What is so special about tennis?!

Only after Hanasawa Rio takes them to watch a tennis match do the special effects flying everywhere overturn their understanding of the world.

Reader's Guide:

1. Silly and lighthearted, with no concern for logic. Lots of everyday life, few matches.

2. The pairing is undecided. The heroine is adored by everyone, but doesn't realize it.

3. Mainly Prince of Tennis, with a little Bungo Stray Dogs and Kuroko's Basketball, and possibly some other crossovers too.

Theme: Pursue your dreams with all your might and become a better version of yourself
