Koutetsujou no Kabaneri: The world has been overrun by zombie-like creatures, and the remaining humans have retreated to strongholds, keeping the zombies out with steam-powered weapons. A caste system has sprung up. Armoured trains run from city to city. And then one of the 'stations' is overrun by the zombies, panic ensues! One young engineer finds a way to kill the zombies, but he needs to get out of the city if he wants to survive...
It's been compared to Attack on Titan, and there are certainly parallels between the two series -- liking AoT is certainly a good predictor of liking this one. The animation is very nice, the characters seem cool (at first glance), and the plot could be interesting.
Sousei no Onmyouji: 14-year old Rokuro was a very powerful exorcist, but he stopped two years ago when his family was killed in a demon incident. Then one day, he catches a girl falling from the sky: she is an exorcist too, and they get caught up in a demon incident. Faced with this demon, Rokuro needs to draw on his experience as an exorcist again to save the day.
Fine for what it is. The character designs are nice and the demons are really unnerving. But in the end, it didn't really grab us -- the exorcisms are more window dressing, and it's probably a "monster of the week"-type of series.
Sakamoto desu ga?: Sakamoto is the coolest guy in the school. Girls want to be with him, guys want to be him. But they get jealous and try all sorts of nasty tricks on him -- which of course all backfire horribly and Sakamoto comes out smelling like roses every time...!
It's like One Punch Man in that the main character can't lose. You'd think that would get stale quite fast, but OPM has shown us that doesn't have to be the case. And the setting is a lot less 'out there', which makes it both more relatable but will also require better comedy writing from the creators.
Netoge no Yome wa Onna no ko ja Nai to Omotta?: Hideki is a nerd who spend most of his free time in an MMORPG. Once he confessed his love to a female character there, but it turned out to be a guy -- so he never trusts female character again. He is part of a guild: two other males and one female. When they declare an 'offline meeting', it turns out that all the guild-members go to the same highschool -- and apart from Hideki, they're all girls.
It's probably 'one of those series', but I liked the set-up. The in-game footage is kinda cool too.
