It’s a bit like Pani Poni Dash, but with drastically fewer sight gags (still plenty of chalkboard scribbles), and instead of a 10-year old genius, the teacher is incredibly pessimistic and repeatedly tries to commit suicide. The counterbalance to the teacher (whose name, when written horizontally, transposes to “despair”) the lead female sees hope in everything, like reinterpretting suicide by hanging to trying to make oneself taller.
Oh yeah, and unlike Lucky Star, this one is made by the people who did PPD.
