During science class, Seki-kun is playing around quietly as usual, but an unexpected pest appears, putting Seki-kun in peril!
There's nothing in here to kill time with.
Nichts drin, mit dem 
man was anstellen könnte.
No tiene nada con qué distraerse.
No hay nada con lo que entretenerse.
Non c'è niente con cui ammazzare il tempo.
Não tem nada que sirva para matar tempo.
