For the majority of the Demon Slayer storyline, Inosuke Hashibira is 15 years old.

His birthday is April 22nd, a detail that perfectly encapsulates his spirited, spring-like energy.

Inosuke's Physicality: A Striking Contradiction
One of the most striking things about Inosuke is the surprising contrast between his physical appearance and his actual age.

This duality adds another layer of intrigue to his character, often catching both fellow characters and readers by surprise.

A Wild Upbringing: How His Past Shaped His Present
Inosuke's age of 15 is just one piece of his complex puzzle. His wild and impulsive personality, along with his incredible survival instincts, are direct results of his extraordinary backstory. After a tragic incident where his mother was killed by a demon, a very young Inosuke—around age two or three—was abandoned and subsequently raised by a family of boars in the rugged mountains. He lived in near-complete isolation from human contact for about 8-9 years, developing an acute understanding of nature and an animalistic approach to life.
This unique upbringing explains his initial lack of social skills, his tendency to challenge anyone he perceives as strong, and his overall "wild child" demeanor. It also granted him an almost superhuman sense of touch and awareness, crucial to his combat style.

Beast Breathing: A Self-Taught Path to Power
By the time he encounters Tanjiro and the Demon Slayer Corps at age 15, Inosuke has already spent years fighting demons on his own. He began battling these creatures around age 11 or 12, accumulating 2-3 years of independent combat experience. This self-taught journey led him to create his own formidable fighting style: Beast Breathing.
Inspired by the movements and instincts of wild animals, Beast Breathing is characterized by its unpredictable nature, incredible agility, and powerful, feral attacks. He dual-wields serrated swords, custom-made to resemble a beast's fangs, perfectly complementing his aggressive and instinct-driven combat. This unique style allows him to track, attack, and defend in ways no other Demon Slayer can.
