History WMG / DeathParade

Nona noted that Decim has only been doing the job for 5 years, but in his bar, we can see mannequins with clothing from at least a century or two back.It also explains with the sheer number of ppl dying every day, there wither need to be an enormous amount of arbiters working to make sure the whole system runs smoothly, or the limited amount of arbiters were given much more time to work. The second seems to be a more probable explanation

Since Light appears two episodes after Tatsumi's death, it can be assumed that Tatsumi dies around the end of Death Note. He has certainly witnessed Kira's killing spree in life, so it's reasonable to assume that his vigilantism is in part inspired by Kira.

It's already an unbelievable coincidence that Mayu should [[spoiler:slip on soap]] and die right at the same time that her favorite pop idol gets [[spoiler:blown up by a time-bomb]]. It's suggested that Mayu actually died well after Harada by the fact that, despite every other guest pair arriving at the same time, Mayu arrived late enough that Harada was already sitting in the bar waiting by the time she left the elevator. It's shown in later episodes that Nona has enough pull over Castra to be able to manipulate which humans get sent to which arbiters, so it's quite possible that she had Mayu paired with Harada and had them sent to Ginti despite them not dying at the same time.

* Also the «Chavott» book and Nonas interest in Onna.

* there's also Nona's last words to Onna in episode 2, and the bit in the elevator with where Nona tells Clavis that Onna's got a ways to go
* Jossed. As it turns out, [[spoiler:Decim is ''an arbiter with human emotions'' because Nona implanted them in him. While Onna is ''an actual human'' who somehow was aware that she was dead when she first entered Quindecim.]]

* Alternately, Ginti was given human emotions, but they were ''negative'' ones as opposed to Decim's positive ones. While Decim shows signs of being compassionate and having self-reflection Ginti is shown to be petty, rude and spiteful. The only other Arbiter we see "at work" is Quin in a flashback but she at least appears to be civil to her guests, which suggests Ginti's an outlier.

* Despite Mayu and Harada both initially showing traits that would justify reincarnation (self-sacrifice), Ginti decides to send them both to the void. This might be explained by how, in a moment of obsessive self-pity, Harada picks up one of the wooden dolls Ginti keeps on display on his counter, ignoring Ginti’s demands to put it down. To make it worse, he absent-mindedly drops it on the floor just to gawk at how Mayu looks in a kimono, which further enrages Ginti. Following this, he puts Harada into a long-term sleep so he can have time to further evaluate Mayu, ignoring the fact that by keeping Mayu present, he’s guilty of exactly what he had recently called Decim out on (being unable to judge a human). Ginti, perhaps vexed by Mayu’s obsession with the fumbling idiot who disrespected his memento, really dug for an excuse to send her otherwise innocent soul off to the void.

Ginti's often shown to be disdainful of humans and even looks down on them. It wouldn't be a surprise if he looked for whatever excuse he could to justify sending someone to the Void. But then Mayu sacrifices herself for Harada (or at least seems to), which shocks Ginti. He can't comprehend someone being that selfless, so he keeps her around to find something that will prove to him that she wasn't. When Mayu agrees to send someone to the Void in exchange for Harada's soul, that's enough proof for him that she was only acting out of self-interest, thus she deserves to be sent to the Void.

* Alternatively Ginti and Decim are two sides of a still ongoing experiment by Nona watching how emotions effect an Arbiter's judgment over time and with different experiences.

For a being who is meant to have no emotions he sure acts emotional more so than Decim in fact. What if there was another attempt at creating an Arbiter who could feel only it didn't work right or did not produce the desired results. It would have either been two difficult or to noticeable to have him completly reset and since he was doing decent work it was decided to leave him at it.

That's also why Light himself made a cameo appearance. The Arbiters know who is responsible.

I think it's pretty heavily implied that Nona's job is cleaning up every other Arbiter's "occasional mistakes". Since these two humans in particular are referred to quite often in later episodes without the slightest shame or regret involved (even from characters with real human emotions), it seems like it wasn't too much trouble to recover their souls and have them sent to their proper place, or having them re-evaluated by a different Arbiter.

There's no question Light can think on his feet, and may have played on Ginti's disdain for humans and his sick amusement.

Yagami Light somehow talked Ginti into sending both Harada and Mayu to the void in order to secure his reincarnation.
