Indeed, it's a shame but what can you do
============
Once again this is a Genjutsu that falls within the "trickery" method. This jutsu manipulates that the opponent see's and experiances in a multitude of ways while keeping the opponent unsure of your current whereabouts.
Advantage: The way this jutsu works is rather bland, some way conciser this a weakness however because it's low ranking and easily recognizable, you can use it to your advantage by fallowing up with a jutsu that truly mask your presence meaning that this jutsu is ideal in quick deception.
Disadvantage: Being a low ranking Genjutsu that requires 5 handseals, it can be easily disrupted meaning that timeing with this jutsu is key. When facing a Chakra sensor or Doujutsu user, it will come to ill effect as with most low-mid ranking Genjutsu's
Possible Usage: Timeing is everything when it comes to some techniques, this is one of them. It's an Ideal Genjutsu to use when an opponent is closing in on you inorder to use a Taijutsu and/or other close combat jutsu. By making the handseals as the opponent closes in, you can place them within the Genjutsu without them knowing, as they make there strike, you will disperse into the sakura petals quickly blinding them. In reality, you could have simply moved out of the way and attacked the opponent as they make the strike as they would be open for attack.
