[Mazui]_Ore_No_Imouto_-_12_True_Route_[LQ][55F8F699].mkv

Totally worth it though. This is the true ending, aka the book ending. It was aired on the web so there's no HQ raw, you only get the raw that was streamed. Not cancerous, but only 360p. I suspect there won't be any better raw until it shows up on BD.
