Bubbled Existence

Using the palm of his hand as a medium, Shūrin casts a genjutsu. After directing their palm outwards towards his target, bubbles and foam start emerging from Shūrin's body. Before the target can notice, they are covered from the bottom up in a sea of froth as their head is encapsulated by a bubble with limited air inside. Inside this illusion, the opponent cannot seem to pop this bubble encasing their head, as the oxygen levels inside it rapidly decrease, the target tends to lose consciousness and falls asleep. The feeling of being asphyxiated is replicated inside this genjutsu. As an additional stage, Shūrin can also make it appear that they are being dragged downwards by what can be vaguely described as a frothy quick-sand, which causes them to struggle more and further spent the limited air inside the bubble, thus knocking them out quicker.
