Genjitsushugi Yuusha no Oukoku Saikenki vol 11??
Several sites imply new Vol 11 of Realist Saves The Kingdom is coming. Japanese version to be published in Oct 2019. However, cover art suggests a modern story versus “another world.” The series 1-10 clearly had a bunch of themes to emerge: Flying cube that attacked Dragon saying come north, the conquest of northern demon region, the mention of celestials, the mercenary country letter to Souza, Eastern Island attack, rescuing excess saints (100?), lots of pregnant brides, and expectation there may be 2-3 more on the way.

No, it suggests we'll get to see a school setting, whether Ginger's or the royal academy or some other educational institution Souma's opened up, with the kids playing a bigger role this time around (I'm guessing from the images on Bookwalker). The cover art features Ichiha and a new girl (Lucy Evans). I say new cause I don't remember her appearing in previous volumes.
