I left a review for the story itself that explains the obvious plot hole. But summed up, you are ignoring the fact they have been forcefully taken from the world and returned home twice now, and should that happen again, they'd be right there next to each other. Not to mention, the girls actually know he is alive cause the queen told them, so theyd know to return and leave a note. The only thing holding this semi together is the fact they can't leave the world with an active quest, which wouldn't be hard to manipulate, not to mention the fact that they can just ask other people to leave a note too.

Fantasy world and concepts. Mc gets guns, exosuits and other mechanical science items.... what's the point of the fantasy world then?

Here's a fantasy novel featuring endless magical paths and other cool things. So naturally let's make the MC mecha-boy and the magic will be a sideshow.

I'm sorry, no one is questioning how he left a besieged city suffering from ongoing attacks?

Err huge plot hole here. They can just return to their world when not on quests. Not to mention the likelihood of the world forcing them to leave due to an event on earth like the giants is high. Seriously author, if you wanted to break Aren up from the group, you should of thought I through more than this.

That's a counter intuitive line. Even with power, you still can't afford kindness. It could be used against you in so many ways. So you'll forever be in search of more power to allow a kindness you will never use. The trick is to only allow a kindness you have the power to back. Thus making our Mcs mindset and actions needlessly cruel in pursuit of the impossible. Be kind where you can, and ruthless where it is needed. Moderation, as in everything in life, is key.

These battle passes ruin the whole point of the battles.... way to kill your stories consistency with drama. Sad writing.

Okay, no idea why it gave a 4 star review. Writing is 3/5. Story Dev is 3/5. Character is 1/5. Update stability is 5/5 World Background 4/5.

This author doesn't seem to have a large vocabulary or even understand the words they are using. Like adapt as a ranking instead of adept, or berserker for that matter.

If he was smart with the other murder, this wouldn't be a problem. He would have the healer ranker with him who could vouch for him. Instead, he mindlessly murdered her. This party was respectful to other rankers so this fight wouldn't have happened. So stupid.
