Lord El-Melloi II Case FilesEdit
Seigen is a practitioner of Shugendou magecraft and is capable of the well-known Raven or Tengu Flight technique. With this he is shown to be able to casually jump several meters in the air in avoidance of an attack.
Later upon being revealed to be the "reincarnation" of the Glannis Ashborn, Jiroubu had inherited the Ashborn's Magic Crest and with it, the Ashborne's Mage craft of affecting, changing, stealing and "tuning" the Magic Crests of other Magus Families. He later displayed the ability to actually "eat" these Magic Crests as well, due to "craving" them because they had looked "delicious" to him.
Also due to inheriting the Ashborne magic crest, Jiroubou had also inherited the ability to command the Adra Castle's guardian familiar to do his bidding.
