I actually feel a little sad giving Momo only a rating 3.5 stars as it does have a lot of potential and has a very promising start. It's just that it loses its momentum and comes to a rather disappointing conclusion and even has a few twists that make me feel a little betrayed as a reader.
To start off with, this has a surprisingly well thought out premise. Momo is a seemingly sugar sweet little girl who also happens to be satan and she's come to destroy earth - that unless her human of choice can convince her otherwise. Enter our main character Yume, caring, hardworking and always short on money - she gets entangled with Momo and her crew. The deal is that it's up to Yume to prove to Momo that the earth is worth saving, namely by making Momo happy through 7 different gestures.
It may sound a bit out there or perhaps a little silly and too sweet, but it is surprisingly well done. Yume makes for a great main character, and Momo is adorable in a good rather than annoying way. The support cast is largely likeable and the gestures range from sweet to thoughtful. A truly nice bond develops between Yume and Momo and also the romance sub-plot between Yume and one of the supporting characters is done well in a way that it doesn't take over the plot but still feels like enough to keep the romance readers happy.
As a whole, it is a very wholesome read with beautiful art and good pacing, until around about the fifth volume when things should start to prepare for the conclusion of the story. !! It is a little difficult to keep this entirely spoiler free, I'll do my best but do not read the remainder of this review if you wish to know absolutely nothing about the ending !! For one, I was very disappointed about the romance. It is not that I think Yume ended up with a bad character or anything along those lines - the character she ended up with is perfectly likeable and a good match for her. What bothered me is that there was no build up - yes there's a history, but it was all off page and the entire series focused on a different couple. I felt a little cheated that it was all thrown over board within a chapter or two just to be replaced with a different character. I could have accepted this if this had been played at from the beginning, and while there were slight hints, it was just far too little for me to accept this drastic change so late in the series.
The ending was also very rushed, I felt like the reveals came several chapters too late and their solutions were as a result terribly rushed. It's a real shame because the series was otherwise well paced and then the last two volumes felt like a big mess where a lot happens way too fast and a lot of it felt half baked. Characters who have been set in their ways for millions of years suddenly needed little to no convincing to change their entire being and some of their choices were just entirely lost on me.
It's still a nice manga, great start, lovely premise that just loses it's way somewhere towards the finish line. I'm still mostly disappointed about the romance though.
with the introduction of miyu, who is trying to become the new female lead, this was a more tedious read and was set up for more complications with the whole "saving the world" thing. still enjoyable, just not the direction i personally enjoy
