you know Chiyuki would know all of this things about the city because it has been established she's a very curious and studious person. Same goes for Kuroki.

The relationship between kuroki and his childhood friend is a driving force to his character but it feels lacking after 50+ chapters

MC and his childhood friend: MC already try everything to get her back, but she don't have a clue about it and think he is bothering her. MC already given up when he was isekai. Although during the first few arc, the MC are written as still lustful toward her. It change after he bedded Kuna after which he always avoid the childhood friend (probably because she is very annoying and don't listen to reason) MC also think that she sleep with the hero.

The Childhood friend (Shirone) written as a clueless to love affair, but she is the type that always degrade the MC because of her own jealously, chasing the other girl always from the MC (MC actually a little popular as well, but due to her degrading of him, has no self-confident) the worse part is, she did it subconsciously, and she always brag about her time with the hero to the MC to rend his heart even further.

However, despite everything, the MC still wish for her happiness (which is being in the hero harem, which she herself didn't actually want at all)

Kuna think that Shirone is someone that might steal the MC from her, so they act like enemy until the last arc before the redo.

At the end before the redo of the story (i read from MTL) due to the MC help to bring ingredent for the an antidote for her, it led Kuna to think the MC like her (Kuna didn't know about the backstory with the hero, otherwise she would have shove that to Shirone face making her regret even more) but since she didn't know that, she think of Shirone as part of MC love interest, so she actually make friend with her.

Which mean if the plot would have advance and at some point Shirone try to confess, there a chance that the MC would refuse her saying he already move on. But that has a low chance of happening since another character name Rena.

Rena is also written to rend the reader heart due to her allowing her people to think that her child with the MC is her child with the hero instead (this point piss me off the most), and I really wish for the MC to say that he won't recognize the child and thought that Rena use memory manipulation magic on him, because she actually did seal the MC memory as well as hiding the fact that she pregnant, she also plan to use her child as the new hero (which is not bad in itself, but she hidden that fact from the MC) worse of all, she make the kid go live with the hero party.

Overall, Rena should have been punish more for her action (the kid was also a result of her raping the MC, then seal his memory of it), she is also suppose to be the main villain as she plan to kill all the hero party after her plan is complete, but due to that r*pe scene her character change into a heroine instead without any punishment.

So I expect that in the redo, Shirone will also be given leniency as well which would suck consider how she act.

Regene is another heroine of which I have mix feeling, because MC doesn't really like her, and even help her to reunited with her own childhood friend, but she choose to be with the hero party as a way to have communication between MC and them, but she also participate in the or*y event. The MC was under aphrodisiac of Kuna, and force Kuna, Regene, and a few of the demon maid, after which Regene almost die, so the MC make her into his apostle. She become a dragonkin due to the MC having draconic power. Which later she was make to manage the lizardmen who worship dragon and left forgotten after the dungeon arc.

Plus, She also work under Kyouka company which are seem as company control by the hero, so that left a bitter taste as well.

One other heroine is Totone, which is also kind of a forgotten character which only shine for 1 arc.

The hero party:

Reiji, basically a talanted womenizer, he bedded most girl that allow him to, but no forcing any that doesn't. This is also why half of the party is actaully not he women. However, it is written in the wiki that 3 of 7 girl in his party have physical relation with him, which I haven't really find anything indicate it, but :

Sahoko, the hero own childhood who have a child with him

Nao, who walk naked after taking a bath just like Reiji

Rino, which is Reiji cousin, so it would have been in*est relationship

Shirone, Chiyuki, and Kaya are view as the hero wife, and Kyouka is the hero sister, however none of them actually in physical relation with him.

Shirone as said above, is not aware of love affair yet.

Chiyuki doesn't want to because Reiji bed too many girl.

Kaya still a Unkown, but she the maid of Kyouka.

Kyouka actually interested in the MC because she are seem as a useless member until the MC give her a simple advice which change her a lot, so she admire him.

is Shirone which sometimes act like she all over the hero, sometimes, act like she regret what she did to the MC, sometime, act like a yandere over the MC. There is no clear distinction of her character until the end of this novel, hopefully she as a better development in the redo.

I also see rumor of her originally was plan to be in actual relation with the hero, but was change later, but I find no prove of it so far.

Regene are written as having follow the hero party after the arc in her kingdom which is use to rend the MC heart as he think that she also like the hero since she technically also a princess (fallen one), but the plot bend to her being in the MC place during the orge event, but later she is back with the hero party (during her time with them, the hero himself are stuck in a dungeon, so she is only with the female member, and she later manage the lizardmen who live near the dungeon, so she stay there.

, even had a child with him

He's "fighting" against the "heroes" on a mountain but it's actually a one sided beat down because he doesn't legit a lift a finger and I don't even know why.

seeing as that the MC wouldn't be cared by his childhood friend, he found the possibility of having someone that would care for him. Only to get his childhood friend meddle with his live controlling what he should/shouldn't have for his life. Bi*ch you didn't even care for him seeing him with pity and disgust like that isn't even helping it. She gets her own time to reflect on her POV but she just brush it of like she cared "time to play with ikemen Hero as one of his [wife], while see that ugly MC can't let him have his life let me try to kill his newfound love interest, oh he cried boohoo~ pity him time to leave him with his pig face friend.. I genuinely puked when she brushed of her chance to understand what in the Mc's mind
