My favourite character is the hero, that is to say Matsuri. How surprising!
She's so cute with her big eyes and purple reflects in her hairs
. Her nature is versatile, just like the wind.
Then, I would say Yorito because he is not, as wtf said, too wimpy. In fact, such as Matsuri, he remains gazing at the stars and suddenly realize he has a beautiful girl near who drinks this odd tomato syrup and illtreat the distributor
Takeshi is also an interesting character, he wants to kill Matsuri for the sake of Mayu. He devoted his whole life to her, to give her a human form and, meanwhile, eventually gave up to please Mayu.
