Can't argue with that xD

Well basically, Rugal's synopsis is that a police officer loses everything he has when he tries to bring down a criminal organization. He gains like superpowers or cutting-edge technology stuff added to his eyes by an unknown group that specializes in that kind of knowledge and it basically helped him to get his revenge. Watch it for yourself if you wanna know why he got like powers for his eyes. It's not a really well-known drama, and it's a bit disliked as well since the writing was meh, but I seemed to enjoy it.

And then Pyramid Game. Yes. THIS one is more than good! I really recommend you to watch this one. It's going to be confusing if I explain it myself so just go to this wiki and read the synopsis. ^^
