The daughter of the owner of the casino cruise liner that Tsuzuki and Hisoka investigate. She has had heart problems ever since she was little, and has relied on treatment from Muraki, whom she has a crush on.    ~!When she was little, she befriended a girl from Hong Kong named Eileen, who was a flower salesgirl. Eileen later boarded Tsubaki's father's ship, but then went missing. It turns out that Eileen was taken by Muraki, who extracted her heart and transplanted it into Tsubaki, who was not aware of any of this at the time.   Eventually, Muraki told Tsubaki the truth, which shocked her greatly. He proceeded to hypnotize Tsubaki into thinking that Eileen's soul lived within her, causing her to develop a dissociative identity disorder, assuming the identity of Eileen from time to time.  At the end of the King of Swords arc, she is shot by Muraki, which wounds her, but does not kill her. She then asks Hisoka to properly kill her, which he ends up doing by shooting her in the heart with the gun that Muraki had shot her with moments before.!~

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.

The business of Death is never done. Asato Tsuzuki works as a Shinigami, or "Guardian of Death," in the Ministry of Hades. It's his duty to make sure that the souls of the dead reach the afterlife, but contrary ghosts and humanity's evils keep getting in the way of a job well done. With all these problem assignments, will he ever get a bonus...or will he be stuck paying back damages for all eternity?
