Innocence[]
Heaven Compass (天針Hevunkonpasu): An equipment type, Heaven Compass takes the form of a large set of acupuncture needles, which Bookman keeps wrapped up in a large scroll and uses for practical as well as combat purposes.
Compass of Spells: North Crime
Compass Of Spells: North Crime (呪縛の針「北ノ罪」,Jubaku no Hari "Nōsu Kuraimu"?) : From a compass-looking like circle that is produced from the spell, a large amount of needles is produced, stabbing the enemy using needles, presumably immobilizing the target. While this attack can destroy multiple Level One and Two Akuma, it had trouble defeating a Level Three. However, since the attack on Headquarters, its power apparently increased as it could destroy a few Level Threes simultaneously.
Needles of Divine Protection: East Crime
Needles of Divine Protection: East Crime (加護の針「東の罪」,Kago no Hari "Īsuto Kuraimu"?) : Used as a protection skill, surrounding a target completely with needles in a circular shape. Bookman can also telekinetically control the needles to move around in a large bunch and act as stepping stones in the air by forming multiple clusters of needles in mid air.
