In the anime , mey rin has a different flashback( i don’t remeber if it is in phantomhive and ghost maybe, if it was in phantomhive and ghost the it is really different.) sebastian found her in the tower while sniping someone and he brought her home to work as a maid then her cool persona change when she wore the glasses
the anime was plotted differently bc the manga wasnt halfway through it so basically the anime surpassed the manga so they decided to create their own story.
