Maybe this (along with Kanokon, Rosario to Vampire, Kiddy Grade II etc) represents a new trend? Is the Hideous Flat Chest fad now going out of fashion amongst otaku in Japan, and lolis with Healthy Chests are the new 'in thing'? Good. I never liked those plank-chested monstrosities anyway. Definitely a case of TITS OR GTFO.
