User blog comment:OH&S/Toaru Majutsu no Index VS Durarara!! Special Collaboration/@comment-15657817-20160331024142

The funny thing is that there are some characters in the Index franchise who resemble characters from the Durarara franchise, or it may be the other way round, but there is a certain resemblance between Kiyama Harumi, Mugino Shizuri, and a minor character named Nasujima Takashi from DRRR, which I thought was a funny little observation.

do the two authors by any stretch of the imagination correspond enough to have done this intentionally?
