tl;dr: A comedic ecchi manga that has a surprising amount of depth and really good character development.

This manga like a lot of Minazuki Suu's works is misleading at first because it just seems like a simple ecchi gag manga. However, as it goes on it turns out to be quite a bit more. The comedy is very heavily centered around the protagonist being a perv that doesn't change his behavior at all despite his schemes and antics constantly resulting in him getting the living daylight beat out of him. However, within the scope of that, there's a good amount of variety to things wherein it never felt like the comedy started to get repetitive and furthermore felt like it was pretty high quality and hilarious throughout.

Something that helped with that is how things were structured, in that the the non-serious light hearted comedic portions are intermixed and flow incredibly well with the serious portions. Generally, the way things are structured is that things will be very light hearted for a while, and then something major will happen where things will get completely serious. Sometimes it's an abrupt shift and sometimes it'll be eased into, but regardless it's generally handled pretty well and keeps things interesting. After the serious part is over, it'll go back to being light hearted and the cycle repeats. However, there'll always be some sort of change or development from the serious portion that carries forward into the light hearted portion, such as a new character, a new power, or change in relationship. Thus, the plot manages to keep a general sense of the plot progressing and things changing while also always having new things to play with in terms of comedy during the light hearted portions. The plot has a surprising amount of depth. It deals with a lot of pretty deep themes, like the importance of freedom, the value in being able to dream, and whether things need to be 'real' in order to make one happy, and they're all written pretty competently and ultimately lead up to answers that are pretty different from most manga but are justified pretty well.

Just as strong is the cast of characters. The main character is interesting and likable, in that during the light hearted portions he's completely useless and just plays around badly which usually results in him getting beat up, but when things get serious he's really reliable and despite being just a human gets things done. The rest of the human characters are decent as well, but the other characters that are especially likable are the angeloids who while all generally being decent enough characters on their own, are really easy to get invested in due to the strength of their character arcs. The character development, which while essentially nonexistant in the protagonist, is incredibly strong in the various angeloids. That it would be so strong in the angeloids isn't that surprising because they start out as incredibly flat characters with no desires so there's a lot of room for growth, but it's still praiseworthy how well it was handled and it resulted in a lot of impactful moments, especially in the ending.

The ending in general was decent but with some issues that seem to stem from being rushed. It isn't rushed in that the conclusion feels forced or out of nowhere, in that it feels like all the major twists and such had been foreshadowed pretty well and it fits well into the narrative and explains essentially everything. So, it's not like the ending itself is the problem, but it seems to try to get through all of it way too quickly with a lot of aspects feeling like they didn't get dramatic enough revelations to have as much impact as they should have. Some may also have a problem in that it seems to be an open ending, but I think that fits well in a series like this. The art is also really good with great character designs and a style that works well with both the comedy and action.
