Ah yes, just what the world needs. Another generic isekai adaption with the same shitty setup as every single one of them; including slavery 5 minutes into the story. Sigh.
To be fair, pets are a normal mechanic in MMOs, and a support main would likely have a single strong pet for solo play. That said, the mechanic is definitely sketch in an isakai situation where they clearly are sapient now.
Especially since his first instict was to fully remove his panties to confirm that he was really there. You'd think that part would have tipped him off
The MC is already cute in such a way they genuinely look like a high-level MMO account, something I really can't say about any of the other generic MMO isakai protagonists. Being a bit of a ditz just made them better.
Overall, this is pretty close to my ideal isakai story. You still have the power fantasy of a high-level character, without it being an overwhelming "they can do anything" that removes all tension. Pair that with the personality of an actual support main -- completely fed up with bullshit and practically sadistic to their teammates with a minor hint of a god complex from their own immortality -- and you have a winner.
Okay, I'll admit I read this somewhat back when it was being put out by a different translator.
