Need I say more? Yes I should lel. This game is a TPS of sorts where you shoot opposing animu waifus with waterguns 'till their little tops pop off, literally. There's online Multiplayer with a variety of modes and a Co-op PvE survival wave mode that's pretty fun too. It's also got a ranked mode relating to that online MP. Yes there is a fully fledged single player mode with a normal story mode, extra side episodes (a lot of them) and a little tournament style form of some of those side episodes. I'd say it's about 30-40 hours of SP content.
