Japanese anime series Terror in Resonance was created by MAPPA. The show was released in 2014. It has aired eleven episodes thus far with no reported fillers.
The present day is nothing like the world that Nine and Twelve live in. They aren’t two teenage boys; rather terrorist masterminds with a plan to destroy Tokyo city. This is, of course, unless their riddle can be solved. SphiRising Peace Academy created this orphaned children academy as human weapons—savants who could decipher any code or enemy moves.
The pair become friends with Lisa, who tangled up with them to expose this organization.
