I'd like to know how you know it's Battler...I don't see his trademark hair.

Most likely the Pixiv tags.

Well, you can see the cape and the sleeves look like Battler´s (gameboard master ver.).

And I still want to retain my sanity saying it´s Batora instead of Goldsmith. Even if we should already know not to put anything past him.

Well, the inner sleeve of the arm is red so i'm betting its Battler

Don't forgot that Kinzo's suit is also white with red undershirt and cape.

A new, more sinister mystery emerges. Who is the Rokkenjima satyromaniac?

Is it Battler or Kinzo?

Both make sense as of Ep7.

Won't put anything past Goldsmith.

The hands aren't those of a wrinkly old mans.

It's Battler.

So who changed the tags to Kinzo again?

No Kinzo/Battler tags on pixiv. Stop adding it.

To this day, the Rokkenjima rapes remain
UNSOLVED

The comment on Pixiv says EP1, and given that the cape doesn't have Battler's trademark vampire pointy things, I'm pretty damn sure it's Kinzo.
