User blog comment:-Saryn-/most powerful phantom troupe members vs most important/@comment-14902757-20140303055810

Maybe to add on to some of the details mentioned, #4 Feitan is their torture guy. #3 Shalnark has access to the hunter site beause he's a licensed hunter. Shalnark also possibly grants the troupe priviliges that the hunter license provides.

I liked the idea of Kortopi being one of the most important members because they are thieves. Kortopi's ability is very useful in thievery.

Shizuku's power actually sucks (aside from literally sucking stuffs) in that she doesn't have means to retrieve whatever it is that's been sucked by Blinky. It all goes into a limbo. What's the point of concealing their crimes when they are not even afraid of the mafia? But Shizuku's cute.

Just another thought though, I think Kalluto is another very important member even though he's new. That's because they never had a member like him before who's able to track and observe people from a distance. A power like that of Flutter would be perfect for their job.
