That's not the danmaku I know.

Bottom right panel, Terminator ?
By the way, in a case that there isn't enough blood/tissue to be "guro", like these pics, then what are they called ?

Disgusting?

@Marc46: Danmaku is explicitly little more than a game in-universe -- it's a non-lethal method of combat defined by a strict rule-set. Were any Touhou characters to actually fight, it'd probably look something like this, given their power levels.

Also, Oni skin is as strong as steel. so a straight on blast would be nothing more then a minor problem to Yuugi if she's swinging for real.
