Well I'd say nothing happening at all is the core of this story and why it's so lovely. It's all about the heroine who suffered her whole life from her selfish friend and who finally encounters endless kindness in a different world. By the fairies, Jade, Chelsea... That relaxing atmosphere is something very rare in storys in general! And it still makes you laugh all the time, even though there is the lingering bitter feeling every now and then resulting from Asahi and that Human-War-loving-Country. Which makes the story interesting for a broader audience. (=・ω・=)
Say what you will, nothing will change my mind that the MC is hella fucking OP and her "power" is basically deus ex machina. All just because she's "special". No different from the usual isekai where the MC is hella fucking OP and everyone loves em and all problems thrown at them are easily solved. Remember, she's loved by the fairies..make her upset and a kingdom is burned down. Sure, it's original in where she can transform into a cat and no one will know but that's about what this story is. You want a relaxing isekai? Then here http://www.mangago.zone/read-manga/tondemo_skill_de_isekai_hourou_meshi/ OP done right, not like the MC who doesn't have to even lift a finger to destroy the whole fucking world.
Also don't worry, nobody pretends that you change opinion. It's yours and everyone can say what they think.
But only one thing, if you read this expecting it to be the classic isekai (wars, guild, battles etc) then of course you would be disappointed. This is just a comedy, meant to be light hearted and fun. The isekai is just the way the author of the novel chose to start the story, if not if would be a classic fantasy.
So, don't get too upset and just move forward. It can happen not to like stories (⌒▽⌒)
Ssooo disappointing, I thought this would be different from any Isekai manga but it's not...nope. MC is a huge Mary Sue with no flaws, indestructible and cannot be harmed because you know why? She got allies that is capable of destruction with a snap of a finger. I've read some reviews for the novel since I was interested in reading it at first but it said all of her problems are easily solved mainly because of the fairies. Boring. Only exciting thing was the war and that was it.
She's just handed with a whole bunch of really nice and OP abilities. She easily understands and learns a whole bunch of stuff without struggle.
Really, the only differing points it has from other isekais is it's gimmick of transformation, it's shoujo and that's it.
