The fuller is connected to both the cross-guard and spear it is a part of on one end, for the other end there is a counter balance.

Personality
Though not much shown about its personality, it seems follows it's masters orders.

History
Jigenso is demon who was sealed inside a long spear. It came into contract a member of the Hyakuya Sect prior to his appearance in the manga.

Story
A member of the Hyakuya Sect renders Yu unconscious via an electrical needle before revealing his true allegiance to Mitsuba. Jigenso is not used to fight her as the agent uses spell tags instead, but it used to escape with Yu. Jigenso appears within the mans hand and follows his command to rip it open. A long thick tear in reality is made as the weapon opens a portal to a different area.

Two identical forms of Jigenso are stabbed into Yu's back in his mind as he tries to recollect his memories.

The weapon is used to allow the Hyakuya Sect agent to join Basteya Irclu atop Shibuya's walls. It is capable of deflecting Shinya's rifle fire, Byakkomaru which causes the former to label it a black demon level before the portal closes behind Basteya.

Jigenso's powers are relied on again used to cause Shinya's fire power at it's master to be redirected towards Crowley instead. It is then physically used in close quarters to fight Shinya, and to open portals where spell tags could pass though.

It is in the hand of the agent who is lying face down in blood and used by Ferid to ambush progenitors Urd Geales, Lest Karr and Ky Luc. The portal opens behind them for Ferid to throw a sinful key to Crowley
