Shikai Submission
Senkou Tsume (Flash Claw)
Concept: Flexibility and Agility
Release Command: Kaihi, Senkou Tsume! (Dodge, Flash Claw!)
Manifestation: Senkou Tsume takes the form of a mongoose. Unlike most mongeese, he is the size of a horse. His fur is a deep silver instead of the normal brown and his eyes are the same emerald shade as Hikaru’s.
Senkou Tsume makes liberal use of sarcasm and logic, and enjoys making fun of his wielder. He is blunt and hates flowery language, preferring instead to jump straight to the heart of the situation. Not for him the enigmatic riddles and mystery-heavy words of other Zanpakuto. If there is something Hikaru needs to do, he’ll tell him.
Form: As Hikaru utters the release phrase, the blade elongates and warps, transforming into a side-sword characteristic of medieval Europe. The crosspiece is worked so that the prongs look like mongoose heads. The handle is wrapped with a mahogany cloth.

In addition, a buckler appears in Hikaru’s left hand. A stylized mongoose head is engraved on the buckler’s middle, and the rim depicts a ring of mongeese chasing each other around the buckler.
Ability: Spirit Skill: Flash Possession (Seishou Takumi: Senkou Senryou)
Hikaru's shikai allows Senkou Tsume to take control of his body for five minutes at a cost of 10% of his reiatsu. The supernatural mongoose's extraordinary skill and experience increase Hikaru's zanjutsu by 5%.
At first, Hikaru can only utilize Senkou Senryou once per day. Every 1000 connection, the amount of times he can utilize Senkou Senryou increases by one, up to a limit of 5 times per every 24 hours. Because Senkou Tsume does not hesitate to employ Hikaru's body in every way he sees fit to the fullest, it takes time for Hikaru to recover enough to use the skill again. Senkou Senryou may only be used once every hour.
Ability 2: Spirit Skill: Speed of the Mongoose (Sumiyaka no Mangu-su)
During Senkou Senryou, Hikaru is also endowed with the speed and reaction time of his spirit's mascot. He receives a 5% bonus to hohou at a further cost of 5% of his reiatsu and is able to perform gymnastic feats and acrobatic skills, such as front-flipping and cartwheeling.
Attack: Raikou Tsume (Lightning Claw)
Senkou Tsume's sole attack manifests itself as an expression of the raw speed contained in Hikaru's body. It is the only one of his abilities not requiring spiritual possession, allowing Hikaru to fight without feeling he is borrowing the strength of others.
Hikaru expends some of his reiatsu, which travels up his sword and infuses it, making the blade begin to vibrate at such high speeds that it becomes a blur.
Mechanically, Hikaru can execute a blinding series of strikes once per two turns, which costs 5% of his reiatsu. The strikes reduce the enemy's combat and agility stats by 2% of Hikaru's connection, topping out at 10%, as the energized blade damages nerves and neural pathways.
