Actually Tiamat is understandable. Remember, she did say if she wasn’t helping run the rating game she would join Issei’s team for the tournament. And if Issei wins the tournament which he probably will and gives her back her treasure this can possibly lead to her liking Issei and becoming his pawn (8 pieces of course)
