I would give to this manga a solid 9 but until I see more development in the future chapters, I'll refrain from rating it so higly.

Story - 9
The plot seems to be childish and silly when you read it, it was very slow and it's still very slow during the last released chapters, but I realized many questions are being answered lately in the newest chapters, furthermore even though at a first glance it will look silly to you, it gets darker and darker.

Art - 8
I won't say it's the best drawn manga I have read, but if you can exclude the "off models" most drawings aren't half bad.

Character - 8
If you can't stand crybabies, then you might hate Lag Seeing to death, even though later in the manga it is explained why he's such a crybaby, it doesn't affect me at all, in my opinion, it's good for a male character to show its emotional side most of the times. About Niche, I was disappointed by her, simply because she's always the same through the whole manga, I don't want this story to turn into a pathetic romance, they're 12 years old after all. I also enjoyed a lot Gauche/Noir's development. Not all the supporting characters are developed as the main characters, but as I said before, the author is working on it and by the reading the latest chapters, I can see he's making many efforts about it.

Enjoyment - 8
Once again, to enjoy fully this manga, a lot of time is required, it's not something you'll enjoy at first glance, but if you have patience you'll enjoy it much more than before.

Overall - 8
I might edit this review later, because the manga has a lot of potential, it just takes time to develop and I'm still looking forward to knowing how the author will decide to develop this story.
