IDK if this has been said already but I'm getting some strong early Cage of Eden vibes from this ... without the prehistoric monsters.
Also, with the blitz of character introductions at the beginning, I'm struggling a bit to remember who is who ... and frankly to care about anybody dying at this point. Well, except water-rapist-kun. He can get dropped in that volcano for all I care ... but we all know that somehow this shitbag still makes it to near the end of the story and will be a problem for the protagonist group. He smells like an antagonist.
Also also, Dude ... don't just rush in there. You've been pretty good about coming up with plans but do a bit more assessment before you charge the enemy stronghold. But I guess the power of the Boner compels you ... I guess there may not be enough blood for both your dick AND your brain.
