Putting Tachibana in the plot role pot for the frazzled Assistant head of the Japanese school [because it fits and also Hayami jokes.] Regardless of if he gets it or not, his magic is via metal sculpture. (Gonna enchant his motorcycle aaawww yeeaaah~)

Bakura's going to be investigating and making magic via making RPG minis. and all the Monster World references. And possibly some dub jokes about him being British.
