Explosive Red Hell Technique

Overview
A technique created to not only trap the opponent, but to be able to strike the opponent within by increasing the user's control of chakra within the barrier. The barrier itself only traps the opponent, but when any person outside who knows how the barrier works channels their chakra into the barrier they can control their chakra perfectly within the barrier. A downside to this technique is it leaves the user vulnerable outside, since they cannot move while channeling their chakra inside the barrier.

Kikatake's use
Kikatake, the creator of this technique, uses the barrier to create various continuous explosions within the barrier. By focusing on a point he can create an infinite amount of explosions at that point, he then moves on to the next point until he covers the whole inside of the barrier. He can also use this to create flames or lightning at any point, though explosions are far more effective.
