Both anime are about a Gyaru main character.
One is a quasi-harem story of a nerdy dweeb getting involved with a gyaru and her gang, one of which is also the story's heroine (Ijiranaide, Nagatoro-san), and the other is a comedy slice of life (Oshiete! Gyaruko-chan), with no romance but just a good high school comedy skit.
