night 2
1 - An Orc (Highness) blocks Hekasan with a burst, but doesn't manage to kill him, dying herself.
2 - Signature: Alexandrite. I have a girl from the fighting game BlazBlue as my avatar; her musical theme in the game is called exactly the same.
2 - This is an incorrect clue. It could only be solved if you knew where the picture came from, that is, only if you knew the game BlazBlue, which I personally hear about for the first time, and the clues should be generally accessible, or at least it should be possible to deduce the game from the picture. But this is impossible if you don't know it.
