His weapon is a Lunacy. His Skill 3 Consumes your Enkephalin and gives bonus Lunacy for clearing the stage, but you have to immediately pull it on the standard banner.
While I can't translate, I do know what scene is being drawn here. Specifically, this is one of the interactions you can have with Jigokku in the postgame where she's raving about getting to shake Sidoh's hand. In short, she just met her god and is losing her mind over it.
Do the extra sails even do anything arrayed like that?
See the artist's commentary. It's not a sail, it's a barrier designed to snag bits of orbital debris. (I'm not saying this is a useful or practical solution, just that it's what the artist intended it to be.)
I feel like a whipple shield made of nextel is just going to create more debris or be ineffective considering that even paint chips can cause impact craters the look like bullet holes.
