Shirou Iori

Iori is quiet, focused, disciplined, and intensely professional. He shows little interest in the theatrical rivalries surrounding Honnouji's club leaders and concentrates instead on the technical requirements of producing functional Goku Uniforms.

His relationship with Satsuki is based on trust. He receives direct orders from her and works closely enough with her inner circle to understand requirements that ordinary club presidents would never be told about.

Iori is also highly adaptable. He treats Life Fibers as materials that can be studied, tested, modified, and countered rather than as incomprehensible supernatural objects.

Iori is an expert tailor and Life Fiber technician. He oversees production of Honnouji's Goku Uniforms and evaluates their performance so later versions can be improved.

His Three-Star Tailor's Regalia enhances his sewing ability through multiple mechanical arms, allowing him to manufacture Goku Uniforms at extraordinary speed. His technical expertise also extends to restraining and modifying Life Fiber-based clothing.

Iori later develops equipment and techniques useful for freeing people trapped inside COVERS and assists with alterations needed for the resistance's final operations against REVOCS.

Iori works behind Honnouji's club system from its earliest stages, producing the uniforms distributed according to student rank. His work allows ordinary students to acquire physical abilities far beyond normal human limits.

He continues refining the Elite Four's uniforms as Ryuuko's victories demonstrate weaknesses in their original designs.

Satsuki's rebellion reveals that Iori's work has been part of preparations against Ragyou and the Life Fibers. After Honnouji falls, Iori joins the surviving resistance forces and applies his tailoring expertise directly against REVOCS.

He later creates improved Three-Star uniforms for the Elite Four and contributes to the clothing-based technology used in the final confrontation.

Satsuki Kiryuuin is Iori's commander and directly relies on his ability to manufacture the uniforms used by her forces.

Mitsuzou Soroi is Iori's uncle and another trusted member of Satsuki's inner circle.

Ira Gamagoori, Nonon Jakuzure, Uzu Sanageyama, and Houka Inumuta wear Three-Star Goku Uniforms developed and maintained through Iori's work.

Ryuuko Matoi's repeated victories provide Iori with practical data about the limitations of Honnouji's uniforms and the capabilities of Senketsu.
