For those who missed the start of Sasami-san@Ganbaranai, you can now get caught up! The anime began streaming on Tokyo Broadcasting System’s on-demand service on Jan. 22.
The main character Sasami is a shut-in high schooler who eats and dresses herself with the least amount of effort. Her older brother dotes on her and cares for her every need. As a shut-in, she often uses her "Brother Surveillance Tool" on her computer to take a peek at the outside world.
As the two try to live out a normal life, bizarre phenomena begin occuring, and three beautiful sisters begin causing mischief. If you haven’t started watching Sasami-san@Ganbaranai, definitely check it out on the TBS on-demand service!
