User blog comment:FieldMagician/No more keshin: how do you feel about it?/@comment-2108497-20130513131106

I'm gonna miss keshin, but I think it was a good idea to balance the players, after all nobody but Tenma, Shindou and Tsurugi can Mixi Max.

In the game I guess those will be forbidden only during the storyline, but will be available after you complete the story.
