although they do need to change the thumbnail, mihashi not being on it is not the reason. in mangago the most recent book cover is the thumbnail. the current cover if book 24, but we are on book 27 or 28 now (ithink)
not 27/28, we are actually closer to volume 30 or so
They should change the thumbnail picture, it doesn't even show the protagonist and his team（￣へ￣）
