Zanpakuto Appearance - Shin's zanpakuto is named Entei. It is of average length for a zanpakuto, five feet long and three inchs wide. The handle is eight inches long, four inches wide. It looks like a normal katana.
Shikai - "Erupt, Entei!" Shin's zanpakuto then transforms into a seven foot long, three inch wide blade. The blade turns red hot, glowing with blazing heat. The heat can be felt from a great distance, a connecting cut on an opponent can set them ablaze.
Bankai - Bakuhatsu Entei-gen - Consumed in flames that are white hot, Shin emerges from them with red and black claw gloved gauntlets upon his forearms and hands. Shoulder pauldrons, upon each shoulders that are red and black in color and etched with gold lions upon them. A black, red, and gold belt with a lion buckle appears around his waist, which is where a black bone like handle is sheathed on each side. When wielded, flaming blades emerge and can also set those that are cut by them ablaze.

Shin's Bankai increases his strength, speed, and is grants him immunity from other flame/heat sources, as it absorbs/devours other flame/heat sources within the area and decreasing the temperature to freezing. A strike from his clawed fists will consume an opponent in a pillar of flames. Shin's zanpakuto is the most powerful fire type zanpakuto, surpassing that of the former Captain Commander Yamamoto.
