Giving the Medaka Box animators a break from providing their recent string of weekly website welcome illustrations, Gainax has turned to TNSK, artist on the manga adaptation of Black Rock Shooter: The Game, for a tribute to 2004 sci-fi OVA Aim for the Top 2!: Diebuster.
Rebuild of Evangelion director Kazuya Tsurumaki helmed the six episode follow up to Hideaki Anno's 1988, in some ways proto-Evangelion, OVA Aim for the Top! Gunbuster.
In January, TNSK was featured in a Wacom live drawing video.
Some more tribute art from TNSK's Pixiv page: (Warning, if you have the a Pixiv's adult filter turned off, TNSK likes doing semi-gory illustrations of a pink haired original character getting tortured)
