Devil Survivor

The Comp, a popular handheld game system that also works as a smartphone, becomes a gateway for demons to enter the human world. Kazuya receives three Comps from his cousin Naoya, a master programmer, and shares them with his friends Atsuro and Yuzu. With demons appearing across Japan, the three must use their Comps to summon and subdue demons of their own. They fight back against the waves of invaders in a struggle to survive.
