The main character, Liam, spends the 10+ million, on "nouveau riche/ easy money" things that they have not earned or deserve. But where is the "going to the next level" and saving all of those enslaved people from the other world? Main character is not that smart, not that capable, has no ethics or sense of justice, and acts like a total hoodlum. It would have been so much better, to have a main character with vision, ambition and capacity for "true heroism".
The two beast-spirit-girls have replaced their "slave-master" to a hoodlum/criminal from another world. There is no difference at all. Of course this is due to the author's bad vision and lack of ethical values.
Again the sex scenes could be completely omitted from this series. Without and charm, without any persuasion, seduction abilities, the attractiveness factor of Liam (is his stolen money/loot), that most of the pirates and corrupt/depraved nobles from the other world had. Liam has no abilities to have his own personal harem. He is not even strong or good looking (of course all thanks to the lack of vision and average writing of the author).
Author like this one, believe that covering it up with sex scenes and depravity, they are giving their readers (their money's worth), but this book and series are missing a better story. Where's the better writing, better organization, better ideas, and better story at?
Liam is supposed to be proficient in armed weapons (guns and rifles) but has not even imagined of taking suppressors (gun silencers) with the weapons he takes to the other world.
