i ncursio 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". In the past, Incursio once belonged to a high-ranking Imperial Army officer and martial arts expert Gensei, who was also Bulat's master, and later came into Bulat's possession and was used during his time under General Liver up until his mission against the Three Beasts with Tatsumi, when he passed it on. Both Bulat and Incursio are so well-known that Wave, upon seeing the Incursio-clad Tatsumi, mistook him for the late 100-Man Slayer in spite of the recent change in form.
