Totally a fan of Tsugumi Seichiro (as i was of Motoko, i have a bias towards these kind of characters), and since she is the black horse of this harem since she doesnt have a key and doesnt have the slightest hance of romance with Raku, and also has to suck it up because she's Chitoge's retainer, the more she falls in love the more i suffer for her.
She has got a huge amount of space in the fillers guess because readers love her and her soft sweet soul together with her tsundere character (and the fact that she's a beehive hitman and they seem to have an array of strange tools to dispose) make her a particularly funny character; unfortunately every and each time the plot moves a little, she completely disappears. The only reason i bear with Paula is because she is the reason Seichiro made that cutest face in the chapter when she and Raku were locked inside the storage room (talk about cliche).
I cannot stand Marika. I understand she is the real key of the whole plot, but i cant stand her. Doesnt make me smile, doesnt me me aww. I find her annoying. Also i wish Onodera's little sister to disappear along with all the first years. We dont need unconsequential characters.
