Natsu no Arashi! Akinaichuu EP7 - Amagigoe

The Master panics, not knowing where she put the ceramic bowl. According to the Master, the bowl that had a bounty of one million yen at "Hako-bune" was gone all of a sudden. Arashi and the others go to search for the bowl using their time leap powers. When they arrive in the past, they find the master just wearing an apron and running around with the bowl. In the end, the master remembers that she had given the bowl to Yayoi for safe keeping, though Yayoi forgets where she placed the bowl.
