Funny story narrated by a girl coping with her all-powerful sister whose nasty acts coincidentally result in positive side effects that make her beloved by everyone. It’s a light comedy and there’s no significant character or relationship growth, either between the MC and her sister or the MC and her love interest. Though the main subject of the manga was how the sister interacted with people, the ending felt abrupt because the ongoing themes relating to the MC were never resolved. I agree with the last reviewer that some of the chapters felt dated (for instance, one suggests that wearing conservative clothes prevents sexual harassment). I filed that away in ‘different culture/year’ and was still able to enjoy the manga.

Hilarious & Problematic

I'm at chapter 22 at this moment: 21 Oct 2019. I might edit this comment again.

I really enjoy this series: It's funny, hectic and straight-faced crazy. The contrast personalities between the two sisters are hilarious and created plenty of hilarities thus far.

By intention, the older sister "the ally of justice" unintentionally. She is seen to have indirectly influenced people to improve and strive to be better or even change their mindset about certain issues in life (i.e. overworking, patience, manners, social behaviours, etc.); Afterward their lives change 180 degree around and most of the time become better.
The little sister also benefits from these although she endured hells from her older sister (from our reader perspectives, the older sister is self-center and cares about no one, even her husband and child, but herself; yet always somehow extremely fortunate and gets everything she demands).

The PROBLEMS arise when some of these indirect "supports", "encouragements" with some being "insults" and downright "bad manners" and "insensitive behaviours" are deeply ingrained as perceived "acceptable behaviours" in society (here Japan, might apply to many other Asian countries).
Personally, these problems are dated and backward and many are contractions and deeply rooted in a patriarch mindset with little progression for women developments.
The moment I realised these outdated ideas - being pushed by the older sister character and author - are no longer tolerable is in chapter 22: a new mother is having absolute hell by-herself trying to take care of her newborn daughter and home without any helping from anyone (be reminded that the older sister stays at her parents home and get her parents and sister to take care of her own baby) while her husband works. By no mean should I weight who is better, who gets it fair, because it's due to personal circumstances. And if you've ever taken care of a newborn baby by yourself or witnessed/supported such guardians everyday, would you have the empathy towards them.
Here, what the new mother needs is sympathy. Instead she got concerning eyes from her circle of friends and downright scorns - even indirect abusive comments - from a stranger/the ally of justice/the older sister.
Then, with those little words of confinement and domestication that entrapped the Japanese/Eastern ideals of a mother and woman, she returns home, fixes herself miraculously by some means no one knows: the house is cleaned, the meals are great, and she suddenly wanted another baby!

I feel absolutely sorry and horrified at this point.

At the same time, I understand that this is way back (2000s circa). Still, I can't shake off how much of a sexist and bully this manga is.

I hope this might be sarcasm or a sort of social commentary work. Or at least provide some insights and internal contexts or personal back stories so we can shed some lights into such an antagonistic character of the older sister. Maybe that would explain her view of the world, and make senses of the person she is to make her less terrible.

One of a kind. Love it.
Simple, really funny, good characters.

The older sister is selfish and arrogant, but smart and I just love how eveything goes her way.
The younger sister is quite annoying, her appearances are only good If her male friend is there.

The art, while clean, is not the most beautiful but it suits every character

the older sister is too despicable that it's not even funny. Instead i find her pretty annoying and wait for her FALL. It's good that her husband couldn't put up with her now so it become more realistic. Or else i'll think, how can u be so awful and get away just like that! no fair!

This is a very unusual manga with an unusual main character: An evil sister who is seen by all as the ally of justice!!

While other manga usually make the main character into some saint in disguise who is, in the end, misunderstood, this girl is truly a cold-blooded demon through and through ha ha ha ha

Somehow, the mangaka reveals the tale of the sisters in a hilariously enjoyable manner!
I greatly recommend reading this.!

Its the funniest Josei that I've ever read, and believe me I've read quite a bit of those. The manga is better than the Drama adaptation, even though both are amazing. There is romance here too, and its realistic and sweet. There is much focus on Youko and her sister, which has me on my fours, rolling with laughter.
I daresay there isnt anyone who would dislike this series one bit.

Unique and brilliantly funny, this is a great read if you want some good comedy. Intriguing and hilarious.
I could so see this be a classic many years from now. They don't make much manga like this.
And oh, this reads really quickly, might be wise to take your time to enjoy it.

SOOOO good! from the summary, i started reading this while not really expecting anything. but right from the first few pages, i definitely fell in love with this series. it's a hilarious story that im sure anyone will enjoy!!! i think this was one of the first josei's i've read, and after the thousands of mangas i've gone through, i think Seigi no Mikata is one of the most unique and well written ones out there. definitely an extraordinary slice of life manga. MUST READ!!!

I have never enjoyed a short manga more. In all honesty, I could not think of a better series - I just wish I could rate this higher!! For those that don't normally read Josei, DON'T BE PUT OFF! This is something that anyone and everyone should enjoy - very fresh and unbelievably funny!! This mangaka may just have the greatest sense of humour in the entire world! smile
