Attacking Fortress (攻撃要塞) is a Shoot Hissatsu/ Defense Hissatsu.
It is used by my fanmade character: Riyona Shimono.
As a Shoot Hissatsu:
A big Fortress rises from the ground then sends many balls flying toward the enemy.
As a Defense Hissatsu:
The Big Foretress falls down at the ball sending the ball being squashed by the big fortress.
