Shirō Iori

Shirō Iori (伊織糸郎) is the president of the Sewing Club.

Appearance
Shirō is a fairly slim individual, although not very tall (evidenced in that he appears a few inches shorter than Satsuki). He has long, yellow-blond hair that goes down to his upper back, tied back in a ponytail while two long, split bangs frame either side of his face. He wears a pair of oval-shaped glasses, and has golden eyes. He is also always seen wearing a transparent orange mask that covers the bottom half of his face.

As a student of the academy and President of the Sewing Club, Shirō dons a Two-Star Goku Uniform. His uniform takes the form of a long, white lab-coat whose ends touch the ground, with two black stars appearing on either flap. Underneath this he wears a black turtleneck and pants, along with black boots.

Personality
Shirō appears to be a very serious, stern individual. He is constantly seen with a frown, and has not yet been seen to smile. However, he does seem to show concern when his superiors (namely Satsuki) are experiencing difficulties.

History
Nothing as of yet is known about Shirō's history, other than that Mitsuzō Soroi is his uncle.

Synopsis
Shirō's first appearance was in episode 2, following Satsuki. He gifts Omiko Hakodate with a Two-Star Goku uniform, stating that it is a gift to her from Satsuki.

In episode 3, Shirō is seen with Hōka Inumuta, observing the test-fitting of a Five-Star Goku uniform in the Sewing Club Laboratory. When the student being tested on breaks loose and rampages, he orders the One-Star security to tranquilize the subject. However, when they fail and the student charges for him, Inumuta intercepts and neutralizes the experiment.

In episode 6, Shirō is seen receiving a large-scale delivery of Life-Fibers, which he says will be used in order to mass-produce Goku Uniforms. Although, when asked by Uzu Sanageyama why they needed more fibers, when the option of more club presidents was brought up, he only replies that quantity would become more important than quality, in that case. Later, after his loss to Ryuko Matoi, Sanageyama comes to him, asking for a favor. That favor being to sew his eyes shut. Despite his own protests, Shirō goes ahead with it at Sanageyama's insistence.

Later, Shirō can be seen at Sanageyama's rematch, watching the fight. When the Three-Star uniform deactivates, just before Sanageyama can strike the finishing blow, Shirō explains that Sanageyama's fast movements overheated the uniform. However, later, Shirō reports that he swapped out the uniform's Life Fibers and restitched it, so it would be able to keep up with Sanageyama's movements and would not overheat again.

While not seen in the beginning of episode 8, he is heard speaking, affirming an order by Satsuki. In response to her command, he orders the commencement of the High-Velocity Life Fiber Jamming Emissions, thereby cutting them off from the events of the Naturals Election. Later on, it is presumable that he is the one to shut it down, and he is seen briefly on a video-com., telling Satsuki when it is time to announce the results of the Naturals Election.

In episode 15, he personaly hands Sanageyama his new Goku Uniform, as he earlier does, presumably, to the rest of the Elite Four.

Satsuki Kiryūin
As President of the Sewing Club, Shirō is an underling of Satsuki's. He serves under her, and is one of the few Two-Star students who has been seen directly speaking with her without bowing. He takes orders directly from her, and follows them to the letter. Furthermore, prior to Satsuki's betrayal of her mother, Shirō is seen having a toast alongside her and the Elite Four, effectively putting him on the importance level of a Three-Star student. Aside from interaction in work, he has shown concern for Satsuki when it appears that her Kamui has been placing too much strain on her body. He is also very loyal to her, and one of his main goals appears to be the completion of her dream for the academy.

Mitsuzō Soroi
Mitsuzō is Shirō's uncle. Though little has been seen of their personal relationship, it appears that Shirō at least holds a certain amount of respect for his uncle.

Uzu Sanageyama
Shirō is the one who made Sanageyama's Three-Star uniform, "Blade Regalia", and then its later versions, "MK.II" and "MK.III". Despite Shirō's status as a Two-Star, and Sanageyama being a Three-Star, they seem to treat each other as equals, without the need for honorifics such as -san or -senpai on Shirō's part. Also, when Sanageyama wanted to have his eyes sewn shut in order to become stronger, he comes to Shirō asking for it as a favor rather than an order.

Hōka Inumuta
Shirō created Inumuta's Three-Star Uniform, "Probe Regalia", and the later "Probe Regalia MK. II". The two are seen communicating and collaborating data constantly, and tend to have a very business-like relationship. Inumuta gathers information and data on Goku uniforms and Life Fibers, and Shirō uses said data in order to make improvements on newer uniforms.

Trivia

 * Shirō's uniform is unique in that it is the only Two-Star Goku Uniform so far not to have any red elements in it.
