Roxism HQ (translator group) description, comment, and opinion:

This is the story about Shimon Kurando, his image is… Well in short he’s just like a fallen warrior. Adventuring in a different world without any cheat abilities or magic except for one, with one goal in his mind, to GET BEAUTIFUL WIVES AND BUILD HIS OWN HAREM!!! [Though he accidentally triggered a wrong FLAG in one story].

Story : SSS
Harem : It’s Over 9000~
MC : Below average
Cheat : Honestly, except for him, most of his enemies are the one with cheat.
NTR : SSS+, to the point that it will break your heart
Heroine : Many of them are big breasted beauty, except for few poor little soul.
Wife Count : He married 10 womans at the same time+1 with a little NTR scene.
Same Sex Description : I will share my sorrow translating this WITH YOU!!!!!!
18+ : just one step away from adult story

Over All : Honestly, I’m quite surprised that no-one translating this yet. The story is basically so good with anti-mainstream and stupid MC, added with mild ero-description [for the sake of spicing the stories], character development, added with quite a lot joke, and NTR scene, it’s just like reading combination of Seigenso and Mushoku Tensei. The down part is, the author highlighting some unnecessary scene which caused quite deep trauma in myself, remember that the theme is NTR!!!, but that can’t stop me from reading this.
-----------------------------------------------
My opinion on the translate story (chapter1-9) so far and prediction of future stuff:
dark and/or gloominess with a strong dose of dark side of human being; while light and dirty joke with idiotic situation.

My opinion on the MC based ch1-9
Chapter 1: the author present the MC with a description that best describe in modern term or slang as a "loser" in human sociality.
Chapter 7: I approve of the tag as defined "the idiot" in the Categories for the MC by this chapter.
Chapter 8: The MC not a pervert, but a "sex offender" in modern term from how I see it in this chapter, but don't worry he get punish in "shocking" way.

My opinion on the MC:
He "an Idiot" but not stupid. There many meaning of idiot and he one of them. (I feel that) the MC not a sex craze person but an opportunities person (in this related topic sentences about sex, a prediction guess of my). Our MC is an "Average Joe" that have no luck with women (such as dating,etc). If giving a chance (like transport to another world), his desire will be unleash (probably from lack of female companion interpersonal interaction experiences such as girlfriend or such). You can said this like a "cause and effect" of sort. At time he a typical Japanese character in any novel, at other time he a fool around "female" making him look like a "cherry boy" character. When it come to female, our MC action and interaction in front of them is a combination "beast", "perverted gentlemen", and a "cherry boy". Only he stop being a fool (like any other person) when come to life and death situation and/or protecting something/or someone he value.

summary of ch1-9 if somewhat detail or not, each chapters seem long or is it just me:

Chapter 1: MC background and the day he got transported to the other world/ The other world situation before the summoning (same timeline, different location); the end of the chapter have our MC get beat up (due to misunderstand) and throw in prison just after he got summon when he didn't do anything (at all).
Chapter 2-6: Prison Life; our MC finally understanding his situation and where he at. I (me the reader) will said "welcome to the cruel reality of Prison Life in a Medieval World. Where Might is Right. Where Title and Position is God, and where Commoner are there, and Non-Human are trash."
Chapter 7: MC flee from prison in a prison riot in the last chapter and headed South. fought off and kill off people trying to capture him again. some villager saw him fought and invite him to stay at their village because they thought he was strong. Villager "uses" (my opinion) a young big breast female villager to request our MC to kill a witch that they believe is the cause of increase monster attack to their village. MC agree (because of the breast power). went to witch house, got attack by house defense before he calm down and able to talk to the witch and get the reason why the monster is attacking.
chapter 8: MC 1st sexual offend: rubbing, touching, grabbing, and feeling a female breast without permission. and yes he got punish. BTW, the so call witch is actually a big breast High Elf (1000+ year old, look 18 or 19 year old) that seem like a NEET.
chapter 9: nothing much to say expect it prove that the High elf is both a kind person and a NEET.

Here some dark side just from ch1-9:
You got Rape (normal, while being NTR) - flashback another person and not about our MC
You got Rape (Homo) - not our MC (not giving nor receiving)
You got Betrayal
You got Brutality & Violent
You got Killing (normal)
You got racial discrimination
You got corrupt people and (government) system

A quick summary of chapter 1 and 2

chapter 1 talk about MC life a little until mc is transported to another world
chapter 2 all hell break lose! mc found himself in a jail where a warden(man) rape man in front of the prisoner. MC also realize he was put into death sentence since he insulted a royalty

yeah after reading this 2 chapter I was like WTF did I just read! It's to much to be a BL! this is the most brutal story of being sent or summon to another world!
