I was imagining a SMT game, located in the Canton of Geneva, Switzerland, instead of Tokyo. There are the
CERN labs there, and they have a particle accelerator. They investigate the collision of particles and create microscopic black holes.
Remember that some years ago, before executing it, somebody spread the rumour that the execution could create a black hole, and so, swallow the earth? I was thinking that the black hole, could be a gate to the expanse, and the main protagonist could be a PhD student working there, and other co-workers/students could join the party, each with their own alignments.
