Schmelman Bach served as one of the instructors of "13th Special Military Forces School" 300 years ago. He is generally portrayed as a calm and collected individual, rarely letting his emotions surface and able to adapt to situations. However, despite the fact that he shows himself to be calm and always smiling, he is also extremely violent once his bloodlust has taken over, as demonstrated when he killed his mother.

Spoiler

It was later revealed that the one who appears in the present time wasn't him. Schmelman in the present time was in fact, a clone of him created by Firenda.
