This is the fandisk to Meiji Tokyo Renka that came out back in 2015 on PSP but I never got to play until now – after Mages ported it into their mobile app and allowed me to play it for free!
Our heroine Emma supposedly drowned in a lake in Paris at the age of 10 and lost all her memories after being rescued. Her father had already been dead due to a prior accident, and her mother then died from an illness so she was adopted by the Vansan family. They moved away from Paris to live with just Arnaud and his mother Alice, and the father, Daniel an army general, was left working in Paris. So basically Arnaud is like her childhood friend she was raised with for the last 7 years. Turns out that Emma is actually witch as well, but she lost her magical powers after the accident. One day she stumbles upon a traveling amusement park called Reve and when she goes there she meets the owner named Hugo who knows that she’s a witch. He tells her that everyone in there including himself is trapped inside and can’t get out without a powerful magic spell, and so he asks Emma to save them. And so Emma becomes an employee of the park, trying to awaken her magic to free everyone in there.
Ayazuki Mei is a gluttonous high school teenager who runs into some do-M wacko named Charlie at a magic show at her local summer festival. Charlie throws her into his magic box and when she comes out, she finds herself thrown back in time into the Meiji era! They’re both hungry so they sneak into a fancy Rokumeikan building but instead of roast beef, they run into famous Meiji era historical figures! So now Mei gets to choose which historical bishie she gets to snag, while dealing with the fact that she’s completely lost all memories of her present time self. On top of this, she magically gains tamayori powers and can see dead people.
