Share a manga that has political or law themes.

Sanctuary is a political thriller manga I read way back then; it's really mature, and I don't know why I read and finished it (maybe because I'm really fascinated by its art style! ). So it's about two men who survived a horrible childhood in Cambodia, and upon arriving in Japan, they realized that it was far from the sanctuary they envisioned it to be. Wanting to change the whole state of Japan, they decided to conquer both the political and underground (yakuza) worlds of it. By the way, it has 100+ chapters (already completed ), and for me it really ended satisfyingly.
