They died and transmigrated at the same time, but were NOT born at the same time. Spider egg only took a few days to hatch while human spent 9+ months in their mother's belly, so physically she's older than them for a few months (except some who reincarnated as different species). Mental age is up to debate because of her certain circumstance.
Yes. Page 4 of this thread has the picture of Volume 9 where the event takes place (no panty shot in this manga though 😭)Didn't she do some nice bondage on the vampire girl in the novel? Or am i misremembering? Or is it for the next chapter?
I'm sure there are some discrepancies with the novel, but this has a lot of smaller problems. It's very clear that the writer put a lot of effort and thought into it, so major props for that. The concept is good, it's interesting to see someone really having to live as a monster rather than being completely humanoid. In the first half or so of the series I really liked the explanations of different strategies during combat.
The biggest problem is the characters have no depth. From the beginning the mc gave the impression of playing a game rather than fighting to survive and she sometimes states values as if she believes in them but her actions show otherwise. The introduction of the parallel wills and other characters just made things much worse. I think the writer eventually felt that the introduction of more characters was necessary and the parallel wills may have been a result of that, but with the writer's skill set it would have been better to focus all their attention on the main character. Also the wills decreased the agency of the mc.
The scaling was not great. Earlier on in terms of stats the mc was powerful, but always gave the impression of being one strike away from dying and would somehow be at low hp despite not having taken many attacks, then she would spam her self-harming abilities like it was nothing. There's definitely too many skills, that much is obvious. You could probably get rid of 80% of them at least and it wouldn't be a problem. Two skills are particularly problematic: the mp as hp skill and the immortal skill. Both of those significantly decrease the feeling of suspense during combat. The leveling and skill ups at convenient times were quite a bit too much. It's fine if it happens sometimes, but it became very repetitive, along with the "I would have died if not for x" events and explanations.
The powerful monsters of the labyrinth were far more intriguing than the more humanoid powerful characters in the later half. The taratact queen was far more menacing than the little girl demon king. I would rather there have been many more powerful monsters with unique abilities and motives that were revealed through their behaviors. TBH I stopped reading at ch 62 but may as well put this here.
It's up to the writer whether she can win without it. We don't know how much raw damage either of their attacks do, the writer just made it up so they can easily just make them do less damage or just give her more health rather than meaninglessly adding an ability that just makes damage even more vague and combat less suspenseful by adding an alternate way that she can survive despite not having health.The Perseverance skill that you mention as MP to HP skill is what allowed her to do some stuff she wouldn't have been able to without it. Attacking Mother (and Ariel) wouldn't have been possible. Surviving Ariel's second attack wouldn't have been possible either.
The immortality skill is not as strong as you think it is. Yes you're immortal, but if your body is destroyed and you have no way to regenerate yourself... well you're screwed. And you're still immortal inside the system, attacks from outside the system can still kill you (like the attack Ariel used on her the second time and Potimas' robots).
For the rest, the source material is a Light Novel where the author takes time to developp every characters (and the world), something the manga decided of not doing for some reasons.
