|Anime debut||Episode 1|
|Japanese voice||Anri Katsu|
Argo Tsukishima is a member of the "Funeral Parlor" who is an expert in hand-to-hand and knife combat.
He has a hot-headed personality and becomes easily angered when someone insults or questions Gai's authority. He has a dark personality that is represented by his Void.
He has been seen always wearing his Funeral Parlor clothes.
PlotHe is seen helping Gai out in different situations and informs him about the 'whitecoats' taking hostages in a building. He also warns him about Daryl, who has a new mecha in his possesion. To save the hostages, Argo distracts the GHQ in order for Gai to carry out his plans. Later, he tells Shu to appologize after saying that only the confident and selfish people succeeded in life (he was refering to Gai) and asks him to join them, he asks Shu if he could extract Voids from anyone. After witnessing his Void's power, Argo asks himself if he's such a dark person deep down, since his Void was the "Light that brings Darkness." He gets angry at Shu because he questioned Gai's plan, causing Shu to run outside. Later, everyone carries out the plan to destroy the Leukocyte and they eventually succeed. Argo is saved by Arisa's grandfather at his estate and was sent past the wall to retreive Arisa before the UN came to eliminate Japan. Argo helps Shu and the gang to save Inori. As he and the others are separated from Shu, they hold off Daryl and his new gespenst. As the building starts to collaspe he convinces Ayase to escape and leave Shu.
- Argo's character design bears strong resemblance to that of Bon from Ao No Exorcist, most notably in their hair-style and face.
