I search manga with the main character that Rich/Wealthy or Powerful (not in strength. But like in finance or politics) BUT s/he hide it...
No one know except him/herself and maybe best/close friend.

The character doesn't have to be perfect... like maybe s/he can be Tsundere, or Yandere... as long as s/he had 'hearts'... 🙄 and has someone they care/love... (beside parents)

Romance or not... i'm fine... (if Romance, i definitely don't search the Love Triangle type!)
As long as not Hentai, or Ecchi, or Yuri/GL...

Complete or not... i take it!
Hope find the long one...

I don't have any example manga... since i don't think i really ever find one... 😐

Please?

Btw, would be more awesome if the character is male! 😀

Onidere, it appears in the story, forgot when though, and pops up every now and then. There's no storyline, no character development, all jokes and continuous gags. If that's your cup of tea, cuz it's the only thing I can think of... It's basically an older Yandere Kanojo with better art.

Arakawa Under the Bridge

Billionaire Girl

Quote from xmariah201

Billionaire Girl

Seconded
Also this goes on a lot in One Outs

The main character has an ongoing bet with the manager of his team regarding his salary that ends up being ridiculously high (he essentially manages the team secretly behind the scenes)

Dear, Only You Don't Know! features a woman yakuza boss who hides this fact from her husband, who thinks she's a meek housewife, lol...

No offense, but none (except maybe this: Dear, Only You Don't Know!) of those even close to what i need! 😢

I think I might know what you're looking for but it's hard to find. If it were anime, I'd say someone like the mastermind in Higashi no Eden. The one you're looking for is a character close to

Mikado Ryuugamine, the protagonist from Durarara!! by NARITA Ryohgo/ SATORIGI Akiyo, right? ! Someone as influencial and well-informed as the leader of Ikebukuro's most powerful gang.

So how about the protagonist from Bokura no Kiseki by KUMETA Natsuo? He was a powerful princess in his former life and tries to uncover his classmates' former identities without being recognised.

Ichtys' Superior is a candidate. The female lead's alter ego is the demon queen but since she is travelling with the hero, she has to keep her real identity a secret.

AKAISHI Michiyo's P.A. could work for you. The heroine is the illegitimate child of two famous and rich actors, so she can't act in public. Therefore, she takes up the identities of other people to solve their problems.

The female leads from DOUMAN Seiman's The Voynich Hotel also fit someway or another, but I don't really think that's what you're looking for. It's just too odd.

Maybe Ratman by INUI Sekihiko? The main character falls more into the strength category but at least he is a super villain in secret.

Have you tried to search for manga tagged with Secret Identity? It might be of help.

Oh right,... Mikado from DRRR! Thanks for remind me! But since the manga not continue being translated in online.. can be count as out of the question.. Tsk! 🙁

And from all of those, i take Bokura no Kiseki. Already on my reading list from long time ago, and i guess almost close to what i search.
