The title 'Koiiji' takes itself on the play of the word 'kuiiji', which means glutton, and implying 'Love Appetite'. In the context of the story, it is more like 'A Glutton for Love', reflecting Mame's long, unrequited love. [taken from nachte's translation]

I was attracted to the art and the idea of reading a manga with older characters as opposed to the school-romance you always see. Mame is 30 years old helping her family run a bath house. What I least expected this to be was a manga full of stereotyped men, women, and a bad script that has no tact.

It makes fun of death, of love, of relationships only to shove the reader with a spoonful of romance genre because that's what the reader is craving for right? They're only looking for romance, no matter the form you dish it out.

Story:
Souta's wife, Haru, died a year back. The mourning period is just being lifted. You'd think a 10 year old kid will have a hard time adjusting, no less her father. But that 10 year old kid tells Mame to marry her dad because she's been in love with him her whole life. Like... uh... Haru didn't love her kid or what? Her child is already anticipating a new replacement relationship. HOW convenient do you want things for Mame?
I'm not asking for brooding characters, but there's no substance at all to their relationships. Sure people should move on, but in this case, I don't see a moving on at all. It just seems outright cold, like nothing happened, as if the funeral was a ruse and there really was noone like Haru. Like the characters themselves don't know what death means because the mangaka did not start by introducing Haru to her own daughter. LOL. It's just fastforwarding.

The rest of the story is about how Mame is rejected over and over by Souta and how she tries to deal with it. I can't say if the manga is rushing, or her feelings have no depth. Maybe both.

Characters:
The men are there for women's racks. The women think of marriage as the ultimate goal of life to world peace. Mame even thinks about her boobs as a way to see Sou naked. Like.. uh.. what? And let's not leave out Brazil as the place with the most crime. It's like.. what you hear is what you get. If you're looking out for a examples with social stereotypes, you should pick this manga up.

LOL... you have a dialogue by a pregnant girl saying, "Even a pregnant woman can kill baby cockroaches." You'd think a pregnant woman will think more about the word 'baby' especially with the word 'kill'. It's really not such a light issue.

I'm aghast at the mangaka, Takako Shimura, who has a work like Hourou Musuko, which, though wasn't the best, but definitely tried to raise issues about gender and bring forth questions. I don't know how the characters are going to develop in Koiiji, but if this is the way you start off, I have no hopes and only feel sick to continue. This is a manga made for the sake of a romance genre. It has nothing to offer in terms of story, no dialogue that will give you a slice of life, and characters that are just so flat and follow the ample tropes you see enough of.

I wish the mangaka invested her time into something more meaningful.
