Let's clean this up a bit.
The Garchomp didn't appear to cut her head off, since it is still very close to her body when she dies. We can assume that, if her head were sliced off, the head would have rolled further. Or there would be plenty of blood.
She would 95% appreciate this. (Yes, Ame is female)
That was Adrienn, a gender-neutral character. Additionally, xe lived in Reborn before crises struck, it seems. The unsettling atmosphere of Reborn is what has given it outstanding acclaim, since it's so real.
Anyway, i r8 8/8 m8, gr8 game. It's definitely difficult, so it is deserving of a 9/10 on the difficulty spectrum.
