Teekyuu

Teekyuu</i> is all about the wacky antics of four schoolgirls—Kanae Shinjou gets bored easily and often breaks the laws of physics to get what she wants; Nasuno Takamiya is incredibly rich and knows how to make things go her way; Marimo Bandou would probably get arrested from her actions like eating panties or kidnapping children; and Yuri Oshimoto, their ordinary junior, rounds out the eccentric bunch that forms the sole members of their school's tennis club. Despite their interest in learning the sport, the older girls prefer messing around, while Yuri, being the only one who actually knows how to play and the most mature in spite of being younger, has to deal with her seniors' out of control behavior. When these four girls come together, insanity ensues in this lightning-paced comedy about a tennis club that doesn't really play tennis. (Source: MAL Rewrite)

Cells at Work!

The average human body contains about 60 trillion cells, and each of them has work to do! But when you get injured, viruses or bacteria invade, or when an allergic reaction flares up, everyone from the silent but deadly white blood cells to the brainy neurons has to work together to get through the crisis!
