Nine

Nine was one of the story's two original protagonists in anime series Terror in Resonance. He is one of the two brains behind Sphinx, an unidentified terrorist organization, along with his boyhood companion Twelve. He is also one of the greatest anime strategists of all time with excellent tactical prowess. He is a cool-headed youngster. His identity and motivations are shrouded in secrecy.

The two frequently rebelled against Rising Peace Academy throughout the series to thwart their self-serving objectives. Nine was clever enough to outwit the academy's researchers, allowing him and Twelve to flee and ultimately bring the facility down.

Despite the fact that Nine is more often cautious and carefully, Twelve continually plays practical jokes and is much more outgoing. As the leader of Sphinx, Nine spends a significant portion of the series developing plans for their organization to implement. Because of Nine's brilliance, the two were able escape authorities for years before the Rising Peace Academy started looking for them. This led to the pair's untimely demise by compelling them to ultimately expose themselves at the end of the series.

Nine is cold, distant, and stoic. He has a talent for coming up with clever criminal plots. He also skillfully hides his tracks using his superior computing and hacking abilities. He was reared with Twelve, who he was most close to, and Five in a children's institution. He had the horrible experience of leaving Five behind as he couldn't save her. He has experienced recurrent nightmares about the incident ever since.
