About a young man that is an orphan but somehow gets to go to school and/or military academy where he has to live in a house that turs out that is was connected to his parents that were kill. I think.
A few years later in the story he take over some business but has he was go to see over them his space ship blew up. When he awakes up he is now in a 14-16 year old Earth boy. Now he remembers is old life, but he really does not get along with the family he has now except the grandfather. The (mc) get into fight with some Mafioso's kid and the (mc) Earth father intervenes because technically his not in Mafia he as dealings with them. So, to keep the (mc) out of trouble he his sent to his grandfather's. His grandfather and him go on trips so the (mc) can learn things.
The last part that I read was about in China or Japan and he was learning from an older woman about his chi or soul, and how to forge a weapon.
Please help me find this story.
Thanks
