So I have been reading the Manga since I finished the Anime series about two years ago and I have been reading up to its current chapter which 112, and my God how the ending of the that chapter happened really got me in the feels.
The overall story of the Manga is that you have Suminoe, Keita who has two step-sisters Suminoe, Riko and Suminoe, Ako, each one has there own personalty but I will be getting to that later. They are in love with him or so it feels that way seeing how he promised to marry one of them when he was very
young (primary school), as he grows his feelings for his elder sister fades and he become a typical middle school/ high school student, sports, friends, thinking about sex, typical guys stuff. Then one day a new teacher shows and my God is she gorgeous looking, Kiryuu, Yuuzuki or Kiryuu-sensei, Keita climbs the academic ladder and then gets in homeroom with Kiryuu-sensei and is immediately in love with her (as would I) but the sisters attempt to bring back their little brothers attention back on them. Typical harem anime but with a twist and to find that twist and its no the faux incest its something else you will have to read the manga that is why I gave it a 9.
The art score I gave a 10 for the sole reason that the artist due well to convey the emotions of the characters and also they do a great way with the eechi stuff that sometimes I feel I should not be reading this in public, but they (the artists) do a great job in inking and the occasional color intro are done gorgeously (I must really like that word seeing how I have said it twice already)
Characters well this is kinda hard because I love the girls in the series each one has a personalty and i feel attached to them but I do have my favorite and my God isn't she the gorgeous one, can you guess who that is? The one thing that I do have an issue with and that is why I gave it a fair ratting of 6, is that Keita seems very cookie-cutter, we kinda see him as your typical protagonist in any other Harem style but there is a twist so you have to see what it is, but I do see that Keita is bit interchangeable with any other male lead in a Harem, he has little to no skills, has all these girls who want him for specific or no reason what so ever (that is the rub there), I would be friends with the guy at school just because he has all the cute girls pawing after him but still he very cookie-cutter.
My enjoyment is of this manga is outstanding a 10 for sure, the Manga sometime has this instance of breaking the 4th wall and also bringing you the reader in and really makes you laugh out loud or even "Gasp!" at certain scenes, even the occasional "I don't think this is a good idea" comes out on occasion. This is definitely a good read and I highly recommend this and up to the point they are in, the writers have some serious explaining to do!
