After securing an impressive Inosuke cosplay costume, 9kekz made a bold decision: he would not don the attire until he felt genuinely deserving of embodying the iconic Demon Slayer character.

Anime Festival Asia 2023 was his deadline, an annual convention held in Singapore, and 9kekz therefore set his sights on achieving a physique worthy of Inosuke Hashibira’s stature.

Despite maintaining a consistent daily workout routine that most of us would consider more than sufficient, 9kekz recognized that achieving his goal for the Inosuke cosplay required an even higher level of commitment and hard work.

“On top of losing body fat, there was also hydration to ensure, to try and get rid of the water retention as much as possible to get definition,” he said. “Being on a calorie deficit is one thing, but all my meals had no sodium, sugar, or carbs. That was the routine at the time.”

9kekz achieved a remarkable 7-8% body fat percentage, a difficult feat to achieve and a testament to his dedication to his Inosuke cosplay.

For context, one of the most iconic physiques seen in cinema is Brad Pitt’s portrayal of the enigmatic Tyler Durden from Fight Club, with reports indicating the Hollywood star hit 5-6% percent body fat for the film.

9kekz embarked on his cosplay journey as a passionate fan, deeply respecting the dedication of cosplayers. Initially, he felt self-conscious in his earlier cosplays.

“I covered myself up quite a bit,” he said. “I started with the military-style Milsim cosplay until I decided I wanted to do an Inosuke cosplay.”

Inosuke’s attire sets him apart from other Demon Slayers, since he doesn’t wear the traditional hakama and haori. Instead, he sports a unique version of the Demon Slayer uniform, featuring only baggy hakama pants in a dark gray-blue hue, fastened around his hips with a thick belt of fluffy brown animal fur.

His leg wraps are replaced with knee-high socks made of furry hide, exposing his heels and toes, which also appear to fasten the sandal bases he wears. His most defining feature is the gray, hollowed-out boar’s head he wears as a mask, concealing his face.

This transformation in his approach to cosplaying marked a significant milestone for 9kekz. While he had always respected cosplayers who went the extra mile to embody their favorite characters, his journey with Inosuke brought him full circle.

“I saw how people would do cosplay, and after just getting to know about how people do it and to what extent, then seeing the attention to detail that people bring into cosplaying and the amount of crafting and handiwork, some of these things are really not simple,” he shared.

“I remember the fun part was – I counted during AFA – I could only take five steps before someone would stop me for a photo,” 9kekz recalled.

He even got photos with a content creator he deeply respects, award-winning webtoon author Merryweather Media. “He’s a big name in the content creation side of things,” explained 9kekz. “He approached me for a photo, which was really honorable.” 

So, why Inosuke?

He explained that he resonates strongly with Inosuke, considering Demon Slayer’s intricate storyline. Starting with the anime, 9kekz was captivated by the series, leading him to continue reading and finishing the manga.
