Black Cat. It's about an Assassin named 13. Don't quite remember much, though I do recall that blonde girl over there can make fists out of her hair.
Alice Academy. Children who are born with special powers known as Alices are sent to the academy. Their status and how well they are treated by the academy is dependent on how useful their Alices are. They are also not allowed contact with the outside world once registered in Alice Academy. There is a lot of discrimination and shady stuff that happens.
MC gets bullied a lot (And I mean like hatred bully not the teasing kind and it makes me blood boil), and is punished by a teacher who hurts her physically.
Honey and Clover. Love story between artists. Very everyday life kinda romance. Little ecchi.
Law of Ueki. If you love JoJo's tactical ****, you'll love this. Each character has a special power which can transform anything into something useful. MC can turn trash into trees, one can turn towels into steel and another beads into bombs.
