At beginning of the manga, KissxSis is your typical formulaic ecchi: an average and relatable teenage boy, some pretty and kinky female characters and a quasi-twincest relationship, with a constant sexual tension and some flavoured school life.

By the 20th chapter, you'll start to sense some character development and the forming of bonds between the main characters as they delve into the story, at a really slow pace. Meanwhile, you'll have some of the best boner-pumping boundary ecchi out there: Ditama Bow is really nice on bringing that horny moments on the manga, and he slowly adds more story between the ecchi moments, which turns out to enhance the quality of the manga.

The female characters are well developed throughout the story, especially the teacher and Mikuni. Instead of simply being vessels for a kind of fetish, they do have feelings, reasoning and well-defined personalities that adds a lot to the manga. Keita and the sisters have a nice development too, though not on the level that those two above mentioned have. We have that lolicon quota - the teacher's sister - which get mastermind roles in some chapters, but later she's shaded due to the other girls protagonism. Much to my liking, must say that.


And if you don't care too much for the plot, the ecchi moments escalate pretty well, sometimes your fapping hand starts to shake.


Positive points:
hi-quality ecchi moments
quality- growing characters
well drawn bodily fluids and kissing scenes
good funny moments

Negative points:
dull ambientation sometimes
