Hey, I have two questions.
One: How come Hanabi doesn't have a cursed seal?
Two: Remember when Naruto and Shikamaru catch Gaara inside Lee's hospital room? When Shikamaru caught Gaara with his kagemane no jutsu, he was hurt when Naruto punched him. However, in Shikamaru's fight with Kin, he was not hurt after Kin smashed her head onto the wall.
Loophole much?
