Actually, info is only useful if its used. Which it was'nt, so nah i still think Sakura is useless/weak. Although, don't get me wrong i love that kishi has made a realistic move in making the hero not get the main girl to like him, but at the same time the author of this manga portrays women as weak so lol she is weak.
Also, i'm not going to comment on the kamui move, its a plot hole and a screw up in the first place. How the hell did Obito manage to send 90% of his body to the other dimension against konan, yet fail at sending just the mere 10% left(when the paper bombs attacked him)? In the latest manga, he sends hs whole body to the other dimension after kakash attacked, yet failed to do the exact same thing against Konan and had to use Izanagi? And thats not even the worst bit. Just how the fck can Obito phase through walls?
If he sends body parts to the other dimension, how does he pass through solid objects? I can get that he teleports them from behind the wall to infront, but the manga has clearly shown him 'passing' through the wall like phasing. Pure, utter bullshit. Unfortunately, kishi is a great artist but not much of a thinker.
