@MucoYes! It's Eris to be exact. Regarding your second question, and please understand that I am very very biased about this series, I 100% recommend it to anyone who reads light novels or likes fantasy/isekai. It's my favorite light novel series and I honestly adore all the characters in it. Just a warning, I know some people did not like Rudy whatsoever due to his nature in the beginning of the story, but he has some of the best character development I have seen in my opinion. 

But yes, definitely give it a read if you have the time and give me your thoughts if you'd like!
(The LN finally got licensed in the West recently which is great news since I've been wanting a physical copy) 

I read the description beforehand and It was one of those MMORPG Light Novels we've excessively. That's why I was approaching it with caution. Thanks for your opinion even if it was biased, I will read it nevertheless  and see for myself.

@MucoYeah the whole isekai craze has definitely made the market over-saturated. If you haven't read it already, The Faraway Paladin is another excellent fantasy isekai. The tone is a bit different from most isekai, almost western-like, but it's still a great read. And you're welcome, I hope you enjoy it, even if just a little bit!
