You misunderstand, what I mean is that the auhtor drastically overshot by making it 150kg. If I one day stepped on a scale and suddenly realize I weigh 2 to 3 times what I did before while not looking any different, my first thought wouldn't be "Oh boy I need to lose this weight" it would be...
Wait wait wait...excuse me? 150 KILOGRAMS?...it would make sense if it was 150 pounds, that's 68 kilograms...did someone mess up here? 150 kg is morbid obesity.
One of the few good yuri manga because it actually gives you what you want from it. Hot lesbian sex scenes. Sad it had to be dropped by the original group because of Seven Shits.
Crow exorcises the demon, the two fall in love, they get married and live happily ever after...knowing this author this might quite possibly be the case, but I'm not betting on it.
