Toki wo Kakeru Hinagiku/Hinagiku's journey through time

It's déjà vu when Hinagiku’s Saint Pendule watch starts behaving very strangely. The entire Saint Hanazono campus is buzzing in preparation for the school anniversary celebration, but Hinagiku seems to have jumped a day ahead and then experiences the same day twice. Watching the soccer team buy out all of the pork cutlet sandwiches again during lunch is the least of her problems. She and the other Love Angels must somehow break the cycle and defeat the slippery time-stealing devil Tanma.
