Incursio

Demon Armor: Incursio is an Armor-type Teigu that takes the form of a short sword with a chain link tassel in its sealed form. Once released, the user is enveloped in a full body armor.

History
Incursio is an Armor-type Teigu created from the flesh of the Danger Beast, Tyrant. The Danger Beast's power was so great that its flesh is still alive within, giving the Teigu the title of "Demon Dragon Armor".

At some point in time, Incursio found its way to Bulat and was used (as far as we know) during his time under General Liver up until his mission with Tatsumi, when he passed it on.

Both Bulat and Incursio are so well-known that Esdeath, upon seeing the Incursio-clad Tatsumi, mistook him for Bulat in spite of the change in form.

Abilities
Due to the Tyrant having an aptitude for adaptation and evolution, the Teigu has also been granted such prowess. As it continues to develop in order to defeat newer opponents, new abilities will be formed, as seen on Tatsumi's first release of Incursio.

When used by Bulat, the armor had the ability to turn the user enveloped by the armor invisible for a certain amount of time, dependent on the skill of the user. It has a near-indestructible defense with the only thing able to pierce it being other Teigu. Bulat (and later on Tatsumi), is able to use Incursio's auxiliary weapon called "Neuntote", a long spear/halberd capable of cutting through Danger Beasts with ease.

Once Tatsumi inherited Incursio, the Teigu went through an evolution in order to adapt to Tatsumi's fighting style and to exceed its previous limitations. The armor that enveloped him was noticeably less bulky then it was previously in order to fit Tatsumi's agile form.

Tatsumi is able to sense that the armor, after its evolution, has new abilities that he had yet to discover. One such abilities is the ability for Incursio to manifest the head of the Tyrant from any point on the armor to deflect bladed weapons, protecting the user from an otherwise decapitating blows.
