In this year's series of Gurren Lagann revival tributes, Gainax has brought in current and former staffers, as well as artists known for their Gundam or other mecha illustrations. After bringing in an ero artist in the last post, another interesting and unexpected artist was featured in the latest. The '90s are back with Rui Araizumi, artist on the Slayers light novels and manga, offering another take on the mecha series.
You can see some recent Rui Araizumi sketches, including a surprising amount of nudes, on Pixiv
and on Twitter @araizumirui
