Let's start with the drawing style. As one can easily say, this work is a Shoujo and so it comes up with the typical art. Bringing out the cute points of the girls, while keeping the guys cool side. The clean outlines are something I really appreciate, while the rest is quite likeable in general. It's not edgy or extravagant, yet appealing in a simple way.
Now the storyline - Well, as others have said it before, the developments are there and can make you shake your head in disbelieve a few times. The main character "Mairu" is rather indecisive and the whole transformation setting is quite common, too. From this side you get nothing special, more like another crybaby heroine thrown into lots of typical situations.
If you wonder, why I still stick with it, it's because of the characters on the sideline. Especially "Kumada Tenyuu" has a decent personality and left me with a nice impression, so hopefully we get to see more of that guy soon again. He is mature for his age and somewhat different, because of his behaviour and background. As for the other side characters, they are funny yet serious in some situations, while the so-called love interest "Narutarou" made me raise an eyebrow, since he acts just as childish and selfish as "Mairu" by times, while considering himself as mature (or manly). Sighs.
Well, things are still going and so this comment is [tbc], but it's not like I expect some serious development or creative twist within the next chapters ... Kind of unfortunate. Sighs, again.
