Japnese Women from our present-day ----------> A Duke daughter who is a Villainess in an Otome Game. Uses her knowledge from reality to help people of her land when running it and introduce new things the world never has seen before (but are familiar and common to us)

Genre = Drama, Romance, Royalty/Noble, Political. 

PS - A manga like this I think is " My Next Life as a Villainess: All Routes Lead to Doom!" 

https://www.anime-planet.com/manga/my-next-life-as-a-villainess-all-routes-lead-to-doom

Both main characters are villainess from an Otome game they have played and have knowledge of. They both aim to have a life where they are no longer a villain and try to make life pleasant for them to live. 

PSS -  "My Next Life as a Villainess: All Routes Lead to Doom!" has more comedy in it that you would also enjoy. 

Personal Imput 

What I love about this manga is that the main character Iris is so clever and ambitious about wanting to help the people in her refief. she puts in all her effort to make their homes and live a better one so they can enjoy their lives and benefits from them. This sounds bad but I especially love when others underestimate her because she always proves them wrong and amazes people with her talent. Basically, she shows them who's BOSS. YAS QUEEN. 

A person who is obsessed with book ----------> Into a little girl from a world with magic and a time where there was no technology or BOOKS! She uses her knowledge from reality to create books.

Genre =  Drama, Romance, Magic, Business/Marketing

Personal Imput 

Her determination to making books is out of this world. I love how to focus she is and how clever a person can be despite her having a mental age of like 30 in a child's body. There are a few mysterious events that make one question and come up with theories as to why that event happens but that whats I love about it. 

School Girl ----------> Has to prove that she is a Priestess of a country in the magical world she has been sent into to live/ survive and has the ability to control water. 

Genre = Drama, Romance, Royalty, Magic

Personal Imput 

This manga is a bit different from other as most of them are set in the west, European like era rather than east, asain era so the law, morals and ways of life are completely different, and that what I find this manga so interseting. Though I believe that the plot can be a lot better.

Personal Imput 

The art of this manga is amazing. The events and activities are always tense and nearby so you always want to read more. The romance is innocent (most of the time) and makes you love it even more. You also come to love Elise passion for helping others and her having no worry or hesitation about exposing her modern knowledge so she can save a life.

Personal Imput 

This manga is soo funny and I love the weird and funny expressions the characters have in each chapter. You find yourself laughing at certain events and feelings she has because as an Otaku myself, I realise that I would have the same idea and expression if I was in that same event. Plus the art is quite amazing, so you find yourself falling in love with the characters even more. The manga also has this mysterious feeling to it so you never get bored.
