Gakkou no Sensei

In the morning of his first day of work, novice teacher Tada Atsushi got into trouble with the principal... and he got fired immediately! On the day that he was finally appointed to another position, he encounters a little boy with round eyes on a snowy mountain road. The little boy shows him the way to his new school, but no matter how he looks at it, the school seems weird?! What exactly is waiting for Atsushi here?!
