even when multiple avatars are in the same place

even now in the later chapters, he's just at home, "Oh I slurped my drink", "Oh my food is here", then, done, switches back to the avatars. Idk, if you were delusional enough you could argue this is a good point: because in the beginning, the setting is that he wants to have these adventures as if he's viewing them from a home theater, and it really feels like that's happening. Minimal MC time, mostly MC's avatars.

Necromantic Lich? Check. Saintly Hero? Check. Vampire? Check. Berserker? Check. Elf? Check. Dwarf? Check. Dragon? Check. Martial Artist? Check. Demon Lord? Check. Growth Through Eating? Check. Mind Mage? Check. Summoner? Check.

All 13 (14 if you count the dead one) of MC's avatars have a distinct and unique personality and it's fun to see how they interact and mesh with eachother. This can be seen especially well in the fight with the Executives. The author uses different avatars for each fight. Doctor got taken down fast but I think that works as a plus. His crazy and unnecessarily detailed rumblings as the Dragon Lair's manager are amusing. The Oracle got wreaked by Heinz, Hoon&Ramyu trio and turned into a staff by Hans & Humphrey. Though the duo (trio if you count Ramyu outside supporting the separated dimension) who took down the Empress was surprising. I didn't expect the Harley-Hela cooperation. Skipping the fact that for last boss phase of the fight Harley got half his body blasted away (but it's fine, it's Harley after all) so in fact the one struggling was Hela. Though honestly it's not the first time they worked together (Chakra dimension wreckage) but the first they fought as a duo so yeah. Hela is a great character actually. She shows the hidden feminity of the MC (which he was extremely disturbed by in the Chakra dimension looking through Harley's eyes lol) and I love how he catches himself involuntarily acting all feminine and becoming embarrassed by it. Never really fully accepting it haha. To all the guys giving low star ratings, you've judged too fast. The MC is constantly growing and discovering himself. All his relationships and reason for existence are explored throughout the series. Even though he met so many people, he felt like those relationships were superficial. That they don't know the "real" him. That's why he valued his best friend and the guy's grandma so much. But at some point he realised that each and every avatar is "him" so all the relationships he made were made by "him" regardless of "his form". Funny that he understood this thanks to the madness guy he defeated as Harley and later traveled with as Han Seung-Hoon who simply told the MC that he should be a man and accept them (the two women) instead of being a coward. Thanks to that surprisingly accurate but misunderstood advice he decided to deepen his relationships with all the people he met not as himself but as an avatar. This enriches his emotional state greatly!

An organization aiming for basically world domination, with a leader that's basically a quasi-god, can't catch someone far below transcendence and has no sense of danger. He allowed his enemies to just run rampant, albeit understandable with "restriction from Akasha" being the resign, an absurd plot design.

Then they set it up so only humans/sub-humans can return to Earth. But then the Author retconned that by introducing demons who, basically lost their humanity and was an entirely different species as their god doesn't drawn design from human design/factor but the devil/demon factor. Maybe being related to the MC is a part of that but Demons themselves pollute their surroundings so the restriction made sense, but maybe the biggest reason it was able to appear on Earth is because it was called via a Unique skill and its Origin was Earth itself. Then they furthermore introduced a Mimic, albeit must have been the cause of the Unique Skill but they are not human anymore but a monster.

Very early on, it's established that people are given abilities and a 24 hour grace period before being isekaid, and that people cause mass destruction during this time, either using their abilities to get resources/equipment before transferring, or just making havok because they think there won't be any consequences, with only a tiny fraction of them returning eventually when they collect enough karma to do so.

Yet later on the same attacks are re-framed as the fault of a secret society, and we see returners with weak abilities (such as a serial killer whose only abilities were related to stealth) that shouldn't have allowed them to gather enough points to return running amok, and there are also so many of them that the MC's vigilante justice rounds up literal hundreds, despite how rare they are supposed to be.

There are also much more straightforward breaks in logic as well, such as it being established that time in the fantasy world passes ten times faster than in the real world, yet when the MC controls his avatars, it's in the same time-frame as his real body.

Or, maybe even more egregiously, it is made extremely explicit that the MC's avatars are completely, 100% immune to all forms of possession and mind control, yet at one point a random vampire just casually mind-controls one of his clones, and then it turns out that he not only didn't have a mind-control ability, but he was from a different fantasy world, so even seniority was out of the question. All so that the plot could be nudged in a certain direction.

And these are just the big ones that come to mind, with many, many smaller discrepancies left unsaid.
