Dangan Ronpa - The Animation Opening HD
I was annoyed that all the versions I found on a search were really subpar quality, but I guess that's what you get for an unknown series outside Japan. To anyone curious, I strongly recommend playing the game instead of watching the anime, it was recently translated which is why interest is at its peak.
It's a murder mystery involving 15 students that excel at one specific thing and could be considered the 'hope for the future', they're all put in an incredibly huge school and told they have to live there forever, or they can kill someone and not get found out which would result in them graduating and escaping; failing that, they're put to death in an excecution that most fits their talent.
