Overview

Personality

Sajuna Inui (乾紗寿叶) is rather headstrong and blunt, despite her child-like appearance. She has no problem with chiding others or speaking harshly when it comes to it, and can be quick to lose her temper as well. Perhaps as a given, she dislikes being seen or referred to as a child, as seen when she first met Wakana Gojo. She is shown to take cosplaying seriously and loves dressing up as characters she adores. This stems from her own dream of wanting to become a "magical girl", a dream that she's had since she was very young, which stemmed from pure admiration when she first saw Shion Nikaido from the Flower Princess Blaze!! series.

Sajuna is willing to go to great lengths if it means getting what she's after, upon learning that Wakana was the one who tailored Marin Kitagawa's Shizuku Kuroe outfit, she followed him home to see where he lives. When Wakana clarified that he doesn't usually make cosplay outfits, Sajuna chose to blackmail him for when he walked in on her in the bathroom while she was naked, threatening to report him to the police as a pervert unless he makes an outfit for her, despite it being a genuine accident that he apologized for. Sajuna isn't always like this however, as she was rather embarrassed to admit that she had stalked Wakana home and sheepishly apologized for it. Much later, she said that he didn't have to make the Black Lily outfit for her if he didn't want to. She also paid Wakana for his work on the outfits after the cosplay session had concluded, despite him saying she didn't have to, saying that creators like him deserve being paid for their work, further showing her gratitude.

It is later revealed that Sajuna was jealous over Marin's cosplay as Shizuku-tan, which is what led her to request an outfit from Wakana. She's aware of how petty being jealous over something is, but justifies that people only feel jealous over things that matter to them. Sajuna even goes as far as to say that seeing the outfit that Wakana had made was "love at first sight". This is why she wanted Wakana himself to make her custom Black Lily outfit, despite there being many professionals who are better than him.

While blunt, Sajuna is perfectly capable of being polite and gracious, whether she's acting as a part of a cosplay or being truly genuine. She is shown to have a fear of thunder and scary places, but does her best to try and hide it. Furthermore, as a student attending an all-girls school, she is shown to be completely inexperienced with the opposite sex, to the point where after Wakana had grabbed her hand, she fainted from pure shock, with it being the very first time a boy of her age group had held her hand.

Sajuna is shown to have reluctance in expressing how she really feels about certain things, likening her to a tsundere.

Sajuna is a cosplayer who mainly dresses up as Magical Girls or Primary School students from anime, due to her youthful appearance. She does not attend cosplay events, revealing that she cosplays for simple enjoyment rather than fame. Her younger sister Shinju, who is also her photographer, was the one who created Sajuna's online account (dubbing Sajuna by the cosplay name "Juju") so she could share Sajuna's cosplaying with others. She soon became extremely popular and amounted many online followers. Shinju did not know how to respond to all the comments her sister was getting, so she just chose to ignore them.

She's super beautiful and her cosplay and photo quality is nothing to scoff at, so she's drowning in follows. - Marin Kitagawa

Relationships

Shinju Inui

Her younger sister, who appears to look older than her despite being a middle school student. While Sajuna doesn't admit it out loud, it's clear that she loves and cares for her sister.

Wakana Gojo

Sajuna saw Wakana's first cosplay outfit online after Marin posted pictures and followed him at a cosplay event until figuring out his name and where he lived. She hired him to make her a costume, saying that it was love at first sight when she saw his previous outfit for Marin. Sajuna is the second person Wakana creates a cosplay outfit for. She fainted when he grabbed her hand while scouting a photo shoot location, given that it was her first time holding hands with someone of the opposite sex. She was extremely happy with how Wakana supported her sister in her first cosplay and thought he was "wonderful" with how he approached her most 'precious things'. It is clearly hinted that Sajuna has developed feelings for him.

Marin Kitagawa

After seeing Marin's tweet that she would be attending a cosplay event as Shizuku Kuroe from Slippery Girls, Sajuna decided to go so she could see her outfit up close, only to be amazed and become jealous of her. At first, Sajuna did not think highly of Marin, seeing her only as a dummy who knew nothing about cosplaying and only liked it because of the outfits. After meeting her face to face however, Sajuna realizes that Marin is the real deal and that she's the type of cosplayer she loves the most: one who takes the characters seriously and to heart. Upon realizing this, Sajuna tearfully apologized to Marin for how she misjudged her, although she didn't get why she was apologizing. Afterwards, Sajuna still finds some of Marin's behavior annoying but still enjoyed cosplaying with her nonetheless.
