In all honesty, the plot for this manga is going nowhere at this point. The author is just elongating the manga with the over-sized harem. I'm not a big fan of harems, in truth, and I think I can handle some harem plots, but I cannot go through with this story anymore. Chapters ago, I praised this story with a much higher rating. Now all I can give it is a four.
I couldn't even bring myself to finish chapter 80, because it was bland. The story is riddled with gags, confusion, and promises that nobody even remembers. Which is another thing I wish the mangaka would focus on. I want to see developement, not a bunch of girls and one guy flopping around in their own pool of embarrassment and anger.
I know this story will come to an end, and Raku will either fall in love with a girl (most likely Chitose or Onodera, rooting for Chitose) or the story will just end with Raku still not with a girl and they're all chasing after him.
But I don't know when that end will be. I mean, I think Chitose is a great character, and the whole yakuza enemy situation is an interesting concept. But the mangaka doesn't indulge in it, the only thing he/she pulls out is the whole protective/crazy bodyguard. Overused, it's something you'll see multiple times whenever the author decides to give Raku and Chitose time together.
I don't particularly like or dislike Onodera. But then, Tsugumi, Tachibana, and Onodera's sister come along.
Worst peeve in the story: Tsugumi. God-awful character, I dislike everything about her. She makes the manga not worth reading. I was hoping she was going to stay as gag relief, but no, the mangaka would never have that, because there just wasn't enough girls.
I praise the art though, wicked action scenes and character designs.
I'll let this manga sit for a while, then come back to it to make my final judgement. But whoever is into crazy, crazy harems, read this story. I'm quite positive (90%), that many of you readers will side with either Chitose or Onodera, because they're really the only relevant characters to any story developement. The first half was pretty good, but I don't know how you'll feel once you get further. Good luck and I hope you enjoy.
