Sakuraba Erika

Summary
The 6th and last hero that has been summoned to the other world, it wasn't said yet where she appeared at the time of the summoning or what happened to her until she caused the revolt that gave birth to the country she leads, The Saint Erika's Democratic Republic, the series talked about her as a ruler loved by the people thanks to her releasing them from the tyranny of the nobles and the sharing of part of the riches that those accumulated, on the country exists a parliament that supposedly has the authority of stopping her decisions but in the practice none goes against her word or wishes, so in the end she isn't that different from a queen that rules the country alone.

On volume 17 it was revealed that she hates the world and every Person on it due to a treason that robbed her of someone who was the most important for her, and above all her hate for herself for being deceived and failing to protect that person, because of that she wants to charge towards destruction while she drags the world and the humanity with her.

For the sake of this she has been taking actions that would cause a great war between the democrats on her side and the royalists on the side of the kings and nobles who don't let go of their power despite being "necessary" for the world's progress, it was for this same reason that she visited Nidor Proxia and tried to provoke him into declaring war to her country, when this failed she decided to make her next attempt with the Galarc Kingdom, but after her failure with Nidor she decided to be even more radical on her way on provoking the kings' anger, doing things like the kidnapping of important figures like Liselotte and the kidnapping attempt on Charlotte and the attack to François and Liselotte's parents on Rio's presence.

Her conversation with Liselotte revealed that she worked as a teacher on a university on Tokyo's Shinsuku's district and showed that she may have developed a disorder of multiple personalities, being her self as the saint Erika something she created after everything that happened to her and her self as Sakuraba Erika something that she stopped needing because she used to have a lover that she can't meet again anymore.
