Let me start by telling you at which point we stopped last week, Maya was attacked by a mysterious monster and Abe-sensei was quietly returning hom from his date.
However Maya didn't return to school, nor did Kozue, so dango haired girl calls Abe-sensei and give him the mission to find them all, ths trying to convey her love for him.
So Abe-sense complies even if he doesn't want to, and find oooh so by chance his "cute" little waitress, she asks him if he wants to come with her to look for them in the car, reluctantly he comes.
And it was indeed a bad idea.
Except that after all she manages to see something on the side of the road while driving at an insane speed (I find that to be quite suspicious, it's like she knew there was something there ^^)
Abe and her walk through, but they got separated, such a shame and Abe comes accross Maya and her silly faces (did I mentionned she tried to kill him?)
While during this time some students and workers of the school were worried and looked for their disappeared principal.
Did I mentionned these two are voiced by Koyasu Takehito (the right guy) and Hiroki Takahashi (the Graham like guy)? It's even funnier
Maya and Abe finally discover the center of the world!
And Abe told her the truth about his fate as a time traveller, basically he was homeless, jobless and their last hope was just killed.
The truth about the Tengu is revealed! It wasn't a Tengu but a Mothman (told you it wouldn't be a Tengu ^^)
And JK defeats him with his magic piano, because music is his life.
During all this time Abe was running away, they still manage to save everyone (including the waitress who comes back unharmed after the fight, suspicious I tell you)
