On February 15th, mangaka Watashiya Kaworu
had a quarrel with another mangaka Yuki Homura ("Sakitama ~Sakuya Den~") on twitter over the sexual expression of manga. Yuki tweeted that one of his acquainted bookstore clerks said he cannot put Comic High!
magazine in the store since it has sexual expressions. Yuki complained that one ecchi manga series can bring disadvantages to all the other manga serialized in the same magazine.
Watashiya asked Yuki if the "ecchi manga" Yuki was talking about was Kodomo no Jikan
. (Note: Both Yuki and Watashiya have been serializing manga in Comic High! magazine.
) Yuki didn't specify the title in question but he told Watashiya it's better to keep the expression of manga within the safety zone set by the regulation of Tokyo government. Watashiya got angry and said she had been making a great effort not to violate the rule. Yuki said he didn't mean to interfere with the creation of Watashiya but he insisted he had a right to make a complaint.
