User blog comment:GouenjiShuuya'123/What is the most powerful Shoot Hissatsu?/@comment-6002029-20120309134826/@comment-4703969-20120310184506

Joker Rains, Fire Tornado DD and Evolution are all powerful (Evolution is pretty much the most powerful non-keshin shoot in the 3DS game), however, they aren't candidates for the strongest shots.

Sorry to say, but Sword of Fire and Sword Excalibur consume 150 KP. They're by far the most powerful in the entire series.

Death Drop hasn't been stopped because GO's goalkeepers are all bad. Tell Tsurugi to try a Death Drop on Senguuji and see what happens...

So yeah~
