WMG: Speed Grapher

Suitengu is actually Sephiroth!
Just watch episode 10.
  • They even have the same Japanese voice actors.

There was no other safe way Saiga could have taken pictures.
Even if he'd only looked to line up the shot and looked away or closed his eyes while he took the picture, the subject still would have exploded, because of the weird way those abilities work.

The Euphoria Factor is like a cancer.
Sure, they'll get special powers but eventually everyone who has it is gonna die in one way or another. I think was made obvious by Kagura's development.

the Roppongi Club is the same secret society from Eyes Wide Shut
come on, it should seem obvious, a secret society that throws parties where the elite can get their rocks off without having to worry about anyone finding out? perhaps what Tom Cruise encounters in Eyes Wide Shut is the western branch of the the Roppongi Club and assuming that the movie takes place in 1999 and the anime in the near future, perhaps Kagura wasn't born yet

Kazuya Shirogane is somehow related to Voldo from the Soul Cailbur gamees
That or Monkey D Luffy

Suitengu's a monster, and his anti-villain schtick is not a side effect but the SOURCE of his power.
Suitengu's power works by shedding his own blood; by the rules of the Euphoria Factor this implies he literally gets off on being a martyr and bearing the pain of others. His whole plan gets revenge on those who wronged him but achieves nothing, since he just replaces the corrupt people he kills with his own corrupt associates, and rips the reasonably innocent of Japan a new one while he's at it, and kills many people who would be forces for change. He never really believed he was doing good in the first place, but the self-righteous act of pretending to is all that excites him.
