On the last page of the 4/1987 issue of Newtype is an ad for Digital Devil Story Megami Tensei, beautifully illustrated by Hiroyuki Kitazume.
This is the OVA that inspired the RPG games.  
Both the games and the OVA are based on the novel of the same name by Aya Nishitani, the difference being that the games (MT1&2) are set after the second novel. Unlike the OVA.
Thank you to Uznare for the correction.

Tenshi no Tamago aka Angel’s Egg VHS release ad in the 1/1986 issue of Newtype illustrated by Yoshitaka Amano. Produced by Tokuma Shoten this anime was a colabo with Yoshitaka Amano & Mamoru Oshii. Give it a try. It has little to no dialog and I can honestly say that I liked it. It’s definitely….different.
