Ok it's official, the imouto is best girl. I always go for the girl with the biggest boobs in any harem, but this time around it's the girl with the second biggest boobs, as she also has the best personality, the best style and the best chemistry with the MC, on top of being wincest bait, she is the full package, it's either a harem ending or sweet home Alabama ending for me right now, anything else won't do.
And I gotta say, whoever the guy translating this is the most funny translator I've ever came across in any manga, this guy deliver one funny line after another without sounding preachy or a try-hard like most other translators who attempt the same thing do. Big kudos to him.
