While in the assessment room, while everyone had been befuddled about the presence of her brown -card, she had used that chance to peek at other student's cards who weren't shy about showing their cards to their friends and who were proud of their attributes.
Most of the cards she saw ended by showing the race or the bloodline of the owner however hers had an extra line and she had every intention of keeping it a secret until she got more information about it.
Mayami felt that it was already bad enough that she got a brown card, she didn't want anyone thinking that she was any weirder than they already thought she was.
The moment she placed the card on the table and Xana looked at it, no one spoke and even Xana who had been busy fiddling with her black card was shocked to see Mayami place a brown card on the table.
