Perhaps not every technique is useful against him. Like those two Curse Masters before; one had the technique of invisibility, and the other had the technique of body substitution, both held no value to Reiger.
Yet, there are techniques that are indeed valuable. Some seemed insignificant at first glance, but their effects made Reiger's eyes light up.
So, no matter what, remembering them is surely the right move.
During this process, some Curse Masters attempted to strike the motionless Reiger, but either they were repelled by the black hound roaming around Reiger, or they were stopped in their tracks by the inviolable [Limitless Curse Technique], unable to harm him.
"Monster...!"
A Curse Master who couldn't touch Reiger no matter how hard he tried, broke down on the spot and roared angrily at Reiger.
What greeted him was a specially delivered shot of [Red] from Reiger.
"Boom!!!"
