B: The Beginning Succession

Months have passed since the events that exposed dark secrets within Cremona. Keith Flick returns to the Royal Investigation Service while continuing an investigation of his own, and Koku and Yuna try to build an ordinary life far from the murders and experiments that stole their childhood.

That peace collapses when Kirisame, Koku’s former companion who was believed to have died at Jaula Blanca, suddenly appears. His survival proves that the experiments are not truly over, and soon Keith is abducted while the identity of Killer B is forced back into action. Koku is caught between someone from his past who claims to be an ally and a conspiracy reaching toward the crown itself. To save Keith and protect Yuna, he must decide whether Kirisame is really the friend he lost or another path back into the organization he escaped.
