This manga had the potential to be pretty good. An isekai with a reasonable MC. It feels pretty grounded, the MC is very realistic about entering dungeons considering how dangerous it is.
Unfortunately, this story has 2 major issues that really drag it down.
1. Progression.
It's established early on that the MC levels 25x(!) faster than normal. He only needs 1/5th the amount of xp per level and get 5x as much xp. He can also equip 6 classes at once, so he should be extremely powerful. He's a warrior/hero/mage/healer at 5x speed, so he's basically an entire party by himself. However in 100+ chapters, his party has just barely cleared floor 13 out of a supposed 99. They also just decided to upgrade from their leather starter gear around chapter 90. This will be 1000+ chapters like One Piece before they clear a dungeon.
I know this is an ecchi manga, but a full half of it takes place in the dungeon and the word "dungeon" is even in the title, so a little more progress wouldn't hurt.
Noticeably the artist stopped showing people's levels because the whole party should be lvl 50-60 while still killing kobolds and rabbits at the entrance to the dungeon. Michio is going to be level 99 wizard/hero/saint multiclass and still farming boars outside of Goldshire.
2. Slavery
For some unknown reason this story is really invested in slavery. And not just slavery, but sexual slavery, and not just sexual slavery, but underage sexual slavery. Why are all the girls 16?! This isn't like some coming of age story, so the age is irrelevant, so why not just age everyone up 2-3 years??? I know they try to say "they consent", but a slave cannot "consent" to anything. The newest girl (Miria) doesn't even speak his language. It just puts this "icky" feeling over the whole thing that doesn't need to be there.
Around chapter ~60 story also stops to let you know, yes this is actual slavery and not like some fantasy spin on prison. Slaves expect to be treated horribly, given cheap worn out rags and being fed just enough to survive, while being made to eat on the floor. What is this adding to the story?? Owning slaves but being nice to them doesn't really make it better, they're still slaves.
It seems like such a simple rewrite to have them all be A) at least 18 and B) not slaves.
To be clear, I am hypocrite, so I did read the whole thing up to the current chapter (107), it's just something at the back of your mind when there's multiple chapters of just boning. "Wow this art is really good. Oh yeah this is an enslaved teenager".
I wanna give some thought too!
about your first point, I agree. the way I see it, the author painted MC life being an adventurer in a isekai like a corporate worker in modern real life. except it is he's grinding and farming monster daily in dungeons to make a living.
the story telling focusing on great detail on two things: 1) planning, prepping, analyzing and learning about fighting and dungeon mechanism works, 2) sex with his women.
the story went into big detail having them discussing many things about how the world Michio lives works, in addition to investment, trading, and bureaucracy.
what makes Isekai meikyuu different from many other isekai manga is that Michio is the MC of the story, but not the MC of the world. he seriously take it upon himself to make him and his harem as lowkey as possible, not wanting to attracting unwanted people. no hero, or savior or the kingdom or that things.
Michio is like living lavishly while being an ordinary people with his cheating skills, mindset, knowledges and power, without the other side of responsibility, fame and making enemies.
it's like, life is just farming and fucking.
as for the second point.... well, firstly this is a work of fiction, and meant to be purely for entertainment. second, the laws, customs, social norms, traditions and what's right and wrong in Michio world is different than in our real life, we cannot judge that the "slavery is wrong" or, "michio is a jerk for enslaving those girls". and about age, well, if the author creating races and characters that are non-human and having different biological traits than human, a fictional characters at that, how we judge if Michio is a pedo for fucking minor or no? it's just silly.
you can't forcing morality if you wanna enjoy this story, especially since there are lots of manga with worse explicit violences and sexuality.
