Subaru Hasegawa is a high school freshman, he joins the basketball team but soon finds out the team is inactive because the captain is being suspected as a lolicon. He miraculously is entangled with the job of being the coach of an elementary schools basketball team. With these girls and their love for basketball Subaru will have a hard time getting acknowledged by each of them.

Kenn's Comment: I'm guessing the title has something to do with 六年生, sixth grader. Anywho, I'm not a big fan of basketball (never really liked the sport), and it reminds me a bit of こどものじかん (Kodomo no Jikan).  It's billed as a loli-sports-comedy, and with the age of the characters, expect very heavy censorship, even on things that aren't usually censored. In the second PV I provided, THAT BALL IS BLOODY HUGE. IT'S LIKE BIGGER THAN HER HEAD! Or maybe she's just really small.
