... *weeps like a small child*
Seriously, I haven't run into an utsuge/nakige hybrid like this since Karenai Sekai last year. Imoten (the nickname for this one) is the latest production by Alcot Honey Comb, the mid-priced subsidiary of Alcot responsible for Satsukoi, 1/2 Summer, and Hatsugamai.
For some reason, in most years, the larger majority of the high quality VNs for the year tend to be put out in the first or last three months of the year... at least, that's the way it has been since 2011, when I first started playing most of the games released during the year. A 'good month' is a month with two VNs that are VN of the Month quality, and of the three I've played so far from October's releases (setting aside the fact that I'm reserving the rest of Freaks for a later date) two have been of that level of quality... and I haven't even started Baldr Bringer.
This VN is based in the same universe as Satsukoi, which was itself a first-class utsuge/nakige hybrid (I won't tell you about the link, since it is a spoiler for both games). Now, this game technically has heroine paths... but by the nature of the way the game's story is told, this game is more focused on the protagonist's struggles than on the heroines. In fact, in order to see the true ending (Touka's), you have to make a rather sad choice near the end of the other three heroine paths. The 'happy endings' of the first three heroine paths are rather short and end abruptly... which makes a lot of sense, in retrospect.
This game's protagonist, Yuki, is the son of two famous actors, who present a good face in public but have been living separate from each other and him since he can remember. After discovering that his mother only birthed him for the sake of putting forth a good social image, he briefly considers suicide, but upon meeting the archangel Touka, who convinces him life is worth living, he agrees to sign a contract to become an angel candidate, with the intention to one day take over from the present god, who is at her limit after a century and a half of keeping humanity from destroying itself and the world. Unfortunately, after a year of living together (Touka having altered reality so that she is seen as his little sister), he has yet to become a true angel, much less reach god's throne. As such, he is regularly scolded (verbally and physically) by Touka and has to endure regular meetings with two other angels... a shinigami (Shizumi) and an angel who is also an idol (Mia) where they try to figure out why he hasn't become an angel yet.
The VN starts out humorous... and indeed, the typical fourth-wall breaking humor Alcot abuses is present constantly here, but things get grim really quick. This is not a kind world, after all.
I'll be straight with you... if you just want normal romance with a great happy ending, this VN isn't for you. The world in this VN is as cruel and cold as the real world, in its own way (think about it... this is the same world where mermaid sisters have to eat their oniichan in order to live... and humans in order to extend that life)... all the more so because the characters are in a position to know, to an extent, why the world is the way it is. If you have a heart, each of the paths will reduce you to tears, each for a different reason... and the choices of Yuki (the protagonist) in order to reach and complete the true story lead to a bittersweet ending which will be hard on those who absolutely need a happy ending.
