Suō recalls a summer day in Vladivostok before the series when she played with Tanya by a pool. Meanwhile, Hei is intercepted by Repnin's men in the train hallway and Suō is confronted by Tanya. Repnin offers Hei a job with the FSB after inviting him to eat. During this time, Hei and Misaki are told simultaneously that Izanami has the ability to cause contractors to commit suicide. Hei refuses Repnin's offer and attacks him, while Tanya summons a swarm of insects to stop the train and escape with Suō. Outside the train, Hei and Suō face off against the FSB force on their own, defeating them. Unknown to Suō, Tanya was killed by Suō's brother Shion from a nearby rooftop. As Tanya floats in the stagnant pool, Suō ponders that she can never return to the innocent summer days she remembers. Suō later heads off to Tokyo with Mao and July on their own without Hei to guide them. (thetvdb.com)
