A ninja history student in Japan sent her education into stealth mode when she turned in a seemingly blank paper for her term essay.

Eimi Haga wrote the essay with invisible ink.

Haga told the BBC that she's been interested in ninjas since she was a child. So when it came time to start her first year at Mie University, she enrolled in a ninja history course.

The professor asked the students to write about a recent visit to a ninja museum, saying he would give high marks for creativity.

"I decided that I would make my essay stand out from others," Haga said,

So Haga employed the technique of "aburidashi," which requires soaking soybeans overnight, crushing them and squeezing them in a cloth. The extract is then mixed with water to create an ink that fades away as it dries.

She handed the top-secret prose to her professor with a note that read, "heat the paper."

He did just that. And much to his surprise, Haga's words became clear as day when he held the paper over his kitchen stove, leaving him no choice but to give her top marks.

Haga admitted that the content of the essay itself was "nothing special," but she was proud of her clever handiwork.

"I was confident that the professor would at least recognize my efforts to make a creative essay," she said.
