Ok, first gonna answer the gold question, do you need to feel scared cause of the NTR tag?
I would say no, in this game it's true that the girls have scenes with other characters other than the hero, but most of them are just the girls getting raped cause you lost to an enemy boss, in fact the only scene that has a NTR feeling is the bad ending which is losing to the final boss.
The girls are only serious about the MC but sometimes under the circunstances that the game have they end up having sex with another character, but that's about it, if you can stomach that in some quests like in the brothel one a girl has ocassional sex with a random character (or the feminine boy that works as the recepcionist of the adventurer guild) then you are good to go, to be fair I just think that the game is very open minded about sex and that's about it. In fact the first thing we see are 2 adventurers teasing the poor recepcionist boy against his will.
Ok, leaving aside all that NTR explanation gonna talk about the game and why I only give it 3 stars:
-The secondary quests are boring and force that the girls have sex, for example there is one in which we have to look for an old man that got lost in the forest, so the characters divide to find him, one of the girls get sleepy and then the old man rapes her in her sleep without her even noticing anything while our MC caught him on the act but didn't say anything (at this point they werent on a relationship).
If there is a problem I see with the game is just those type of situations, it's just weird. I would have eliminated all of those to be fair cause of that.
-The MC personality is kind of like how the pharaon of legend of queen opala was, doesn't truly care that one of the girls has sex with other people if she remains in love with him, I would say on the love aspect they are loyal, they don't develop feelings for other characters at all.
I would have liked some yuri action rather than that... but seriously, it's an aptitude a bit too open.
-The gameplay is kind of average, nothing special, kill monsters -> level up -> buy better gear then repeat, that's all it is, in fact there is no use for the money except buying better gear.
I would have liked a fame system and that the MC could actually fight, I have to say that the preview is at the very least misleading.
But that's about it, no pathetic MC, the girls love the MC, only some absurd comedy and situations have the girls have sex with other people (except the recepcionist boy which is kind of teased and rewarded by the girls sometimes), if you are a chill person like me you can play it from beginning to end with no problem, if it bothers you a lot that they sometimes get raped or tease the recepcionist boy then just leave.
