Some years ago I started reading a manga and then I completely forgot the name of it and I hadn't saved it anywhere.（/TДT)/
I remember the first chapter presented a new guy, he was quite poor and lived in a one-room and he had some kind of powers because he fixed his heather using them. This was like 10 ago and it was already old by then. Its art style reminded me of 20th Century Boys or Akira, so its probably that old.

I'm pretty sure it was a seinen.
