Punch Line is a modestly ecchi themed anime, that fortunately does not stick to it very strongly for the majority of the show. The introduction is understandably giddy and, luckily, tries not to take itself too seriously. Panties, nosebleeds, apocalypse, the trailer definitely does those justice, but don't let it fool you. The focus of the show switches to a more suitable theme very quickly, saving the viewers--mine for sure--interest. The somewhat serious nature of the show, with comedy relief, gives a decent mix of dark undertones and dumb up-skirt. If you're looking for an ecchi harem comedy, this isn't the place to stop. The themes are much more serious and subtle, with only a sprinkling of the panty shots in the early episodes.
The soundtrack was pretty well crafted, but is honestly not memorable at all. It is very quiet and non-invasive, instead adding to the atmosphere of any given scene. I cannot recall a single tune or melody after finishing the show, and failed to come up with anything substantial skimming throught the episodes or checking videos online. The opening theme, however, is quite memorable. It starts out being a rather irritating poppy tune resembling the supposed underwear centric show, but grows to be more cheeky and a very excellent contrast to the actual mood of the shows middle and ending arcs.
The secondary characters in Punch Line eventually become lovable, though extremely ditzy and irritating early on. An extensive amount of time is spent on the viewers chances to learn about everyone and their personalities--slice of life--and none of the characters are snubbed of their deserved time on screen. The main character, and their past, is especially interesting. I wont comment on Chiranosuke... not a fan.
I would recommend this as a filler anime if you're contemplating on the next 50+ episode anime you'd like to watch. Though it was an enjoyable experience, Punch Line is not a must watch nor is it outstanding by any means. Give it a try if you're having trouble picking something worth your while.
