4. Welcome to the N.H.K.

Twenty-two-year-old college dropout Tatsuhiro Satou has been a hikikomori for almost four years now. In his isolation, he has come to believe in many obscure conspiracy theories, but there is one in particular which he holds unshakable faith in: the theory that the evil conspirator behind his shut-in NEET status is the Nihon Hikikomori Kyokai —an evil and secret organization dedicated to fostering the spread of hikikomori culture.

NHK ni Youkoso! is a psychological dramedy that follows Tatsuhiro as he strives to escape from the NHK's wicked machinations and the disease of self-wrought isolation, while struggling to even just leave his apartment and find a job. His unexpected encounter with the mysterious Misaki Nakahara might signal a reversal of fortune for Tatsuhiro, but with this meeting comes the inevitable cost of having to face his greatest fear—society.

3. Hidamari Sketch x Honeycomb

Studying at the Yamabuki Arts High School has been a dream-come-true for Yuno, and she's learned so much already! And not just from her instructors, but from her friends and neighbors who've become her second family and made the Hidamari Apartments such a safe and nurturing home. But as the day of her "big sisters" Sae and Hiro's graduation draws slowly closer, it's time for Yuno to start seriously taking on the same role for Nazuna, Nori and the other budding young artists who've entered Hidemari's protective cocoon. And it's also time to tackle some really challenging artistic assignments. That doesn't mean there won't still be time for fun with Miyako and all the others, but it's definitely time to pencil in her plans for the future. And sometimes that means you have to put the art before the course!

1. Great Teacher Onizuka

Onizuka is a reformed biker gang leader who has his sights set on an honorable new ambition: to become the world's greatest teacher... for the purpose of meeting sexy high school girls. Okay, so he's mostly reformed.

However, strict administrators and a class of ruthless delinquents stand between Onizuka and his goal and they will use any means, however illegal or low, to drive the new teacher away. Perfect, because Onizuka's methods won't be found in any teaching manual; he cares about the difference between legal and illegal activities about as much as he cares for the age difference between himself and a high school girl.

So get ready for math that doesn't add up, language you'd be slapped for using, and biology that would make a grown man blush... unless of course, you're the Great Teacher Onizuka.
