Here's some artwork for a few of the retail-separate bonus items Boost On is readying for its latest PSP adventure game, Yami Kara no Izanai Tenebrae I. The artwork is from manga artist Hiroshi Itaba, who headed up character design work on the game.
I choose not to know anything about this game. However, based off the screenshots at the official site, it seems to be about big busted girls, guns pointed straight at the screen, and green cadavers who somehow cling to their cell phones for life... the very life that they lack!
Here's the game's opening movie.
