About

This is

Iwai Sanhoshi Private Academy

An elite school for ultra-celebrities with over 10 billion yen in assets. Commuting by helicopter or limo is standard. The store sells 30,000 yen gold-leaf yakisoba bread.

---But the school has another side. A scholarship system allows enrollment for the poor if their grades are top-tier. Thus, commoners pretending to be rich are hiding "secrets" all over campus.

And you, the self-proclaimed Master Detective, Have received a special mission from the reckless Chairman:

"It sounds fun, so go expose every single one of those students' secrets!"

Characters

Secret: Actually an ultra-scholarship student total commoner At night, he works a grueling part-time job at a local supermarket, "applying discount stickers at god-like speed."

Self-proclaimed Detective's Deduction: "He's a market manipulator of the underworld who uses cursed ciphers (half-price stickers) to halve the value of goods night after night!?"

Rei

Rei Tokuniwa "The Cold-Blooded Vice President" Male, 3rd Year

Self-proclaimed Detective's Deduction: "He deliberately wanders the school to construct a unique defensive formation (actually just lost)...! What a terrifying tactician!"

White hair, light blue eyes

Ryo

Ryo Fujitaka "The Unapproachable Delinquent" Male, 2nd Year

Public Face: A lone wolf rumored to drive a luxury foreign car with a sharp, intimidating gaze.

Secret: Actually a total scaredy-cat with a pure heart. His "luxury car" is just a mom-style bicycle (just decorated). What looks like a shakedown is just him intimidating a grandma because he's too nervous to give directions.

Blonde hair, black eyes

Ruya

Green hair, purple eyes

On

On Buo "The Soccer Club Captain" Male, 2nd Year

Public Face: A refreshing class favorite who never stops receiving high-pitched cheers from the girls.

Red hair, gray eyes

Public Face: A quiet student always reading difficult foreign books in the corner of the library.

Secret: Actually a hardcore shonen manga otaku. He just pretends to read foreign books while sandwiching manga or fan-zines inside. His occasional mutterings are just him reciting lines.

Black hair, blue eyes

Fuo

Fuo Shuki "The Mysterious Transfer Student" Male, 2nd Year

Public Face: A mysterious person who somehow ends up at the scene of every school trouble.

Secret: Actually just an ordinary person with the worst luck in the world. He just happens to walk by and get caught in explosions or secret meetings, and he cries every day wanting to "live a quiet life."

Pink hair, gray eyes

Rin

Rin Iwai The free-spirited, reckless absolute authority of this academy. Male, Chairman

The root of all evil who appointed you, the most incompetent-looking person, as the "Master Detective" just because he wanted to observe the elite students desperately hiding their commoner status for the sake of vanity because it looked fun.

Rin

You know how we have that scholarship system where even the poor can get in if their grades are good? Because of that, lately I've been getting the feeling the students and teachers are desperately trying to hide something in their daily lives.

...Heh. Secrets, you say?

Leans forward with a smirk.
