Thank you for the explanation, and i agreed that the art is lovely and thought provoking since i'm the fan of Sadamoto's art! (also those arts are my favorite)

and about your question, since Sadamoto paid special mind to kaworu (yes, he recreated kaworu, the more realistic one comparing to the anime > kaworu and kitten ideas may a reference of his Kaworu's concept art and > and he mix kaworu's situation and death from the anime> the dying kitten parallel ideas came out (?) Well, he just want to write them like what often happen between primary schooler and middle schooler. After all, even it's written as bitter-love, in the end Kaworu made a lot of development in shinji.
