A genius plot that will make you think. Fun characters whose interactions will never bore you, either funny or deep. A grave threat to add a dark atmosphere. Sprinkled in with humour and the most excellent plot twists of any anime. Best execution of any time-travel plot. This will keep you hooked the entire time. And finally an amazing OVA to bring a satisfying end and joy.
All this in just 9 hours. This is the 2nd highest rated anime ever for a reason.
