Phantom Task 20-2006.jpg

Phantom Task  (亡国機業ファントム・タスク, Fantomu Tasuku?) is an antagonistic underground organization who hid in the shadows. They revealed themselves recently during the IS Academy's anniversary. It was a group notorious for stealing IS from all over the world and equipping them with deadly pilots that will kill other IS pilots. 


The organization is known as [Ruined Country Weaving Industry] - [Phantom Task]. It had seen over 50 years of operations and according to the rumour, the organization is born from the second 'big war' (that could refer to World War II). They have no allegiance to any country, religious cause, or ideology and the races of the people involved is unknown. That is why the organization is so difficult to predict. They also had numeral clashes with the Sarashiki family, who in turn had some underground dealings. There are two main groups in the organization. The Board of directors who manages the organization and the Operational squad full of various specialists. They began targeting IS's due to their deadly potential to wreak havoc internationally.[1]

It also managed to stay in the shadows because countries who lost their IS's to them refused to announce their losses, as it would put them on a disadvantageous position to rival countries. This is strongly due to the fact that a country with more IS cores will have an advantage in the political monopoly. This is proven by Chifuyu Orimura when she once commented that IS cores are things any country would desire.[2] Another reason for concealing the loss of an IS, as pointed out by Laura Bodewig, is that it would inflict a heavy loss on the national defence side. Thus nobody would reveal that their IS's got stolen.[3]


During their first strike at the IS Academy's anniversary, Laura was convinced that Phantom Task was a really large group not to be underestimated due to the infiltration capabilities of the members and their high-level skills in IS battles.[3]

Autumn also revealed that Phantom Task was responsible for Ichika's childhood kidnapping and rigging Chifuyu's match. The purpose of this so far is unclear. It is also currently unknown who ordered and orchestrated his kidnapping.[3]
