Shiki's Pins

Shiki's Player Pin marks her as a participant in the Reaper's Game. It is her badge of participation, and if another person touches it, it can be used to form a Pact with them, granting them increased combat effectiveness against Noise and Taboo Noise. It also has a unique ability, hereafter referred to as a Psych: its ability is Scan, which allows Shiki to telepathically scan the surface thoughts of non-Players, and to see the unique sigils which denote a buildup of Noise.

The blank Fusion Pin was given both to Shiki and Neku by Mr. Hanekoma. Although it exhibits no power on its own, if Shiki has a Pact with another person, then it allows them to use a Fusion attack. This is a coordinated combination assault which raises in power and scope depending on the bond with another person.

All four of these pins offer Shiki access to the Piercing Pillar ability. This allows her to create an ice-elemental attack in the form of a stalagmite, which also has the unique tattoo-like quality of many pin attacks. Each pin creates a pillar of varying power level, from Ice Blow being the weakest to Blizzard Cool being the strongest.

These three pins allow Shiki to use the Psychokinesis psych. Depending on the number of pins she uses, the effectiveness increases. Psychokinesis allows her to lift any nearby objects or items that are not in use, no matter their size or weight, and use them as blunt objects to smash her enemies with.

Earthshake is a pin which grants access to the Earthquake psych. This allows Shiki to shake up the ground to perform a nature-elemental attack, although it is not particularly strong and mostly useful for shaking up large groups of Heartless and knocking them around.	Blown Kiss is a non-combat pin which Shiki keeps around to complete her D+B collection. Outside of combat, it allows her to heal by regenerating her health and body, meaning she does not need to rely so heavily on food, potions or other resources to keep herself healthy.	Love Me Tether is a non-D+B brand pin. It belongs to the brand Natural Puppy, which features an assortment of simple, brightly coloured and cute design clothes. When using the pin's Entanglement psych, Shiki can create binding chains made of thread or fabric.	When used in conjunction with Love Me Tether, Straitjacket upgrades the attack to Entanglement Plus, decreasing an opponent's accuracy by binding their limbs.
The D+B pin grants the Resonance: D+B psych. This powers up all D+B pins, allowing Shiki to use them in a combo attack.	The Eyes Have It is a popular pin, said to be used by lady Reapers if you want to win another's heart. Shiki took it from Uzuki Yashiro one time. Using its Frostbite psych, she can create ice attacks like a Blizzard spell, or freeze an enemy in binding ice crystals.	Nikkari is a non-D+B brand pin. It belongs to the brand Jupiter of the Monkey, which offers urban, sporty clothing. Its psych, Lance Lunge, allows Shiki to create a tattoo-covered needle and thrust forward, knocking opponents around with a charge.	Go 2 Heaven is also a non-D+B brand pin. It belongs to the brand Tigre Punks, which sells pre-ripped and patchy punk gear. It also lets her create a needle, and its psych Spear Strike lets her use it as a weapon.
