The premise of this manga is pretty broken. This story is about a girl named Iroha and well the description tells you the rest, though her brother gets dragged along with the story too. But while he's not completely trivial, he's more of a sounding board.
Anyway Iroha already acts like a typical manga girl. She even looks feminine.
Soon after I started reading I thought this manga was going to suck. The characters were basically being forced through something against their wills because of someone else's opinion. It's kind of a dick move for a dead spirit of an ancestor to do*.
But I don't want to be overly negative. The main character is likeable enough and the comic is ok. I'm not really sure who this would appeal to, it's best to read it as the average comic(comedy, but not romantic) it is then to think it's premise will put it into any niche field.
It's generally good natured and harmless. If I did rate this it'd be an ok average read, it has it's funny moments and all.
*Actually let me explain the premise because the description only tells half the story. The ancestor spirits or whatever decide to resurrect their grandmother, and alter their gender to their opposite while they sleep because they feel that the boy doesn't act manly and the girl doesn't act feminine based on their ideas. Iroha is understandably annoyed/freaked out that someone did this to her and tries to switch back by being more girly though she does things she would have done anyway like wear a bra, panty, and her school uniform. That actually plays into the family's plan anyway, though I guess it's win-win because if they don't switch they end up with the girl or boy that they feel acts correctly anyway.
