Himouto! Umaru-chan Season 2 Coming Fall 2017

The second season of the comedy anime will debut later this year.

The series continues to look at the titular Umaru, who in public is a model student and good citizen, respected and beloved by all, but in private, acts childish and selfish, not wanting to do anything except laze about, overindulge in her hobbies, and have fun with her friends.

If you haven’t seen the first season, be like Umaru and bingewatch all twelve episodes right now.

The official announcement video:

Happy National Siblings Day!

Marie Karigari Hiroshi smiles weakly as tears stream out of Hiroshi Karigari's eyes

Siblings. They make us laugh; they make us cry; they make us angry; they make us proud; they make us worry; they make us jealous and everything else under the sun–sometimes, all at once. Above all else, they’re family, so take some time to celebrate your siblings today. (If for no other reason than to say that you remembered to and they didn’t.)
