Abyss Break

Haru Shinagawa releases four natures from his cards; fire, water, earth and wind and combine them to form a barrier. Once the barrier is completed, a huge explosion will occur, dealing massive damage.

The user is safe from the explosion due to the barrier created during the technique's casting.
