Kyoto Arc Part 1
A serial killer taking a lock of hair from each victim leads Hisoka and Tsuzuki to Kyoto, Watari's home town. When a lock of the murderer's hair is found at the scene of the latest victim, the pair discover that their criminal is none other than Dr Muraki and a run in with the evil doctor leaves Tsuzuki battling with memories of his past. However Muraki knows more about Tsuzuki's past than he is letting on, and what Tsuzki doesn't know could just be his downfall.

Descendants of Darkness
Even after death, life is full of paperwork and criminals. Tsuzuki Asato is a 26 year old, happy-go-lucky, and dorky shinigami (god of death) whose job is to makes sure that those who are dead remain dead and stay in their proper realms. Even though he's had this job for over 70 years, he is in the worst division with horrible pay. He also has a knack for not keeping partners (since shinigami work in pairs), but now he seems to have one that will stick around; stubborn, smart-mouthed, serious and defensive 16 year old, Kurosaki Hisoka. With each case they investigate, they come closer to the conspiracies of the serial killer Dr. Muraki Kazutaka. Tsuzuki's relationship with Hisoka is growing stronger and closer...but there is a dark past to how Tsuzuki died that will not give him peace.
