Hi all,
I need help in finding the name of a manga I read about 15 years ago.  I think it's within a few years of Cyborg 009.  The manga is about the life of a cyborg in futuristic settings.  He's previously a human.  He gets into an accident and his scientist sister replaces most of his bodies with robotic parts.  Later, they find out that humans who have their parts replaced develop special power such as telekinetic, teleportation, force shield etc.   People with more part replaced get more power, so the protagonist is near the top in term of power.  His first conflict is with another cyborg who replaces all of his body except the brain.  At the same time, people discover that due to conflict between the robotic parts and human body, all the cyborgs develop dysfunctional psyche (except our main hero, of course).   So, the other cyborgs revolt, they kill his sister.  He kills them for revenge.

The story goes to to tell his life after that incident.  Since he lives pretty much forever, he moves from places to places to keep people from discovering his true identity and to hide from organizations who want his powers.  Every girl in his life ends up dead.  So, it's a bit tragic in that sense.

I'd be grateful if anyone could tell me the name of this manga.  Been trying to revisit the mangas I read as a kid and I just can't find anything on this one
