A lot of the comments about this series is negative, mostly saying that the girls are sluts. That's pretty offensive and ignorant. The only time you will find sluts are in hentai manga. Did the author make hentai before? Yes. Is this borderline? Eh. Is the story the best/most original? No way.
Not sure what I was doing with that.
They are virgins. Virginity does not mean virtuous. It means they have not had sex. It does not mean they can't be aggressive, masturbate, or sexually interested.
Well, artwork: Yes, the drawings aren't amazing. They're quire ordinary and at times, the character's faces/eyes aren't very distinct. But each of the girls are different and meant to fulfill a certain type of woman in build and character. This can be attributed to the author's work on hentai where the focus is on character rather than story. So at times, the expressions are very expressive... which sounds contradictory to what I wrote at the start.
Story: Its generic in the sense that a guy is on the receiving end of several love interest. What sets this apart from other ones is that all the girls are aggressive in their approach. Don't expect shy or coy moments, the women are all wolves. This does mean that there are fan service but that isn't the focal point of the story. A lot of similar manga does gag fan service (To Love-Ru/Negima/etc) where most of the fan service aren't influential to the story. In this manga, they are all actions in which the girls are trying to win the favor of the guy.
It is extreme in that they show their panties or various body parts
but the fan service never takes up the whole chapter and easily forgotten once the chapter ends if you don't dwell on it. I guess... its like seeing nudists at a nudist beach.
Characters: At first, they seem generic girls and guys but if you get past the "oh, they're sluts" prejudice its interesting. From the start, everyone knows what they want and how it plays out requires further reading.
Main character-
Kaneda Wataru- Wants to be independent to unburden his mother in terms of finances. He doesn't recall his childhood so the unexpected three fiancees doesn't allow him much reaction. He does get embarrassed but is quite frank with his opinions. So far, it just seems like he accepts the situation but does step his foot down if things get too far.
Kurebayashi Tomo- She's Wataru's classmate, friend, neighbor, and daughter of Wataru's landlord. She loves him but has yet to make a move. She's quite quick to temper due to the other thee's aggressive advances. She's also easily embarrassed.
She officially joins the fight in ch.9 and is essentially a TSUNdere
Ougi Tamayo- She's possibly blond and a bombshell.
As for her personality she's an exhibitionist and yandere. This makes her quite the sadist in ch.7-8 as she taunts her fellow competitors during her date with Wataru. She also masturbates. Which people do.
Aikyou Rika- Typically with twin tails and possibly brown hair, she works as a model.
She shares a commonality with Wataru in that they both dream to be independent. Of the three, she seems more easy going and admits in ch.5 that she wasn't serious about competing for Wataru until then. She also seems laid back and light hearted in her approach.
Mayuzumi Sanae- Petite black haired girl.
She has an odd thought process which shows in her actions and words. She's really strong and really just want Wataru's babies via ch.6. She loves to eat and sleep. In a sense, her love is pure.
New girl
Mayuzumi Koyuki- Eh... she's super smart, wears glasses, and has big breasts...her connection to the pact is a slightly funny story and is often a point overlooked; usually only noticed by in mystery novels...but there are tripods too so...eh. As of ch.21 I have yet to feel her necessity to the story.
tl;dr- Honestly, chapter nine pretty much sets the stage. Four girls trying to get a guy, there are service scenes but they all progress the story. Most of them. The service scenes are adult so if you can't handle that...its you. Its comedic in the clash of personalities but honest in its story. There are mixture of approach to romance. But they all love him with all their heart.
6.5/10 because it could have been hentai (for better or worse). The story is easily summed up. What makes it great is the clash of dynamic personalities and approaches. I'm sure there are more serious tones later on but for now, as of ch.21, its alright.
