I - Backstory (AT)

(akitoya again, probably) Aliens invade Earth to escape their planet's zombie disease. Unbeknownst to everyone, a new, nearly undetectable variant was transported to our planet.
Akito gets the disease and has 30 days until it starts to eat him alive. Toya does everything he can to save him . . . but will it be enough?

Features all Project Sekai main characters.
