The 14th volume hasn't been released yet but overlap usually releases a preview of the novel on their site so people can read a sample before they buy it. If you go page 27 of that preview (Counting backwards as the lines are supposed to be read right to left), the sixth line from the left starts with おや、... and ends with. うん

That line basically translates to that everyone can see the transparent window that popped up and they confirm that Rinnew is mikan's master.
