Yeah, in the original MoF/SA portraits of Sanae, she has toothpaste for hair.
Anyway, there weren't anything what made me 'lol' but there was a lot of 'WTF O_o' moments... Actually the whole UFO itself was like that. First in the demo, the Brofist. Then in the full game: "wtf the giant ball of light is shooting SPACE FAIRIES!", then first spellcard of Murasa "Holy shit it's a Freaking ANCHOR???!!!" and died in an instant. Then in the fifth stage, "WTF Am In the Cyberspace?? With SPACE FAIRIES??!! O_o", "Holy shit CURVING LAZERZ!!" then "Spinning lazer cross of death, What The Hell!". When I've reached Byakuren, I was already exhausted from the so much wtf-ing.
