Yakuza Reincarnation - Yakuza Princess of Another World - https://mangadex.org/title/43476/yakuza-reincarnation I'm really liking the first chapter. I like the art and the attention given to the MC's first life really shows a level of depth, passion and care that mindless isekais lack.
The 2nd chapter gave a good idea what happening in the country and to the princess. At leat the MC is not a doormat-ish(till now).
