I have a question. I have to find one anime series but I know only some details about it. It s an old one not an actual. It s about one world dominated of one bad guy who s taking his power from one strange drink and of what I remeber the name was black torrent or something like that. And in this world it was a child raised by his grandfather and I don t know his purpose anymore why he wanted revenge with this bad guy. The action was somehow happening in the future. The child is raising and when the bad guy and the child had a fight he is drinking that devil drink but a little bit to save his life and after that he s becoming crazy too. Of what I remember but I don t know for sure. Before this bad guy only in their family who was drinking that drink became evil. And from what I remember the bad guy was the father of the child.
