Immortality... FAIL.

Immortality means jack all if you can't take a punch

Just a clarification. I think a better translation of 不死身 (lit. "undying body"), in context, is "invincible" rather than "immortal". Am making the appropriate changes. And, as observed here, the point is that Murasa is nowhere near invincible.

yo dawg, I herd you like ghosts
