A while back a lot of man and little girl couples were being mainstreamed in anime. Example: no-game-nolife, and Black Bullet.

Luckily, this trend stopped. BUT recently, there seems to be a number of shows promoting adult-female and little girl couples.

• From last anime season there was Happy Sugar Life, in which the two main characters are lovers

• This season we have Uchi no Maid ga Uzasugiru! which even seems to use pedophile symbols
