I get what you are saying Jammin but besides Kuroumaru and Eva I don't think relationships have been well built. I guess it helps because they were the first companions.
Karin's arcs were too fast and in the end it doesn't look like we'll learn much about her past. I find that Touta's characterization became worse later. Santa has been mostly irrelevant after his arc. Kirie did get a lot of screen time but mostly for repetitive stuff (I hate Kirie so I might be very biased here).
Akamatsu must be really tired.
Anyway, I am really hoping for an unambiguous happy ending.
