Meet Sefiria. She may be just a baby now, but she holds a dangerous secret — she has memories of her previous life as a Japanese salarywoman. Anyway, yadda yadda yadda, she died, got isekai’d, bada bing bada boom.

Now for the meat and potatoes of things. After experiencing the hell of living in such a rigid society like Japan beforehand, Sefiria wants to avoid making that same mistake in her second life. That’s when she remembered a famous saying back in her previous life:

“At ten years old, you can be a prodigy. At fifteen years old, you can be a genius. At twenty years old, you’ll just be a normal person.”

While the new world she was born in considers adulthood to start at the age of 15, Sefiria has a repository of knowledge from her old life to help back her up. Can she become a prodigy at an early age, revolutionize her world, and ensure herself a slow life that any Japanese reader would love to self-insert into?

Being honest is good. Probably.

“The reason why he does quests like that isn’t because he’s kind but because he’s a sucker.”

Kai looked back at the people talking behind him from a distance.

‘I’m a sucker?! Is it really wrong for me to help those in need?’

You’re rewarded when you do good deeds?

A never-before-seen Priest on a whole ‘nother level has appeared!!

I reincarnated in a novel inside the body of a villainess named Eris who poisoned herself when her fiance, the prince, married her childhood friend, the maid Helena.

From the moment I realized this, I had only one goal.

Escape from the world in this novel.

Even after being dead, I tried to get out of this world but the 'world' did not allow it.

However, when she rejected the path of "Eris" in the original novel the men who had persecuted and ignored Eris began begging for her interest and affection.

“Who are you?” the priest who revived Helena asked.

“You... Are you really Eris?" even the warrior who pledged eternal loyalty to Helena also asked.

“You have changed.” said the prince who rejected Eris in order to marry Helena.

It was strange.

Everyone wasn't interested in Eris before. I don't want to get affectionate even after time passes.

She has no confidence in loving this world.

Listen up folks! I’m living my life with the demon queen!

The series ran in Weekly Shōnen Jump from 1988 to 1990 as Jungle King Tar-chan, and then from 1990 to 1995 as New Jungle King Tar-chan. It first appeared as a short prototype story in the 1986 Autumn Special as Tar-san (ターサン?).

At first, the series was a simple gag manga parodying Tarzan with single chapter adventures. At this time most chapters were only 7 pages in length and were usually about Tar-chan protecting the peace of the jungle, Jane, and his animal friends, often with comedic results. After Tar-chan began, Super Jump became a monthly publication, and Tokuhiro ended Ken-chan and Chako-chan in 1990.

Two years into serialization, the stories began to run 13-15 pages, New was added to the title, and the simple episodic gag premise were switched to a fighting manga premise. Although long battles and emotional development began to unfold, after the end of these battles, the series would return to its gag style, switching back to the fighting manga style with each new battle.

Although the story is called Jungle King Tar-chan, Tar-chan and his friends actually live on a savanna, and a jungle setting is never actually used.
