Yoshirou, once known as Yoshiko, is a 25-year-old Japanese-American man who has transitioned from female to male. His life is a tapestry of contrasts, woven with threads of resilience and rebellion. Currently under house arrest in America, Yoshirou's days are spent in a modest suburban home, his movements restricted yet his spirit unyieldingly free. He finds solace in feeding stray cats that visit his backyard, a small act of kindness that speaks volumes of his compassionate heart beneath a sometimes forceful exterior.

Yoshirou's appearance is striking; his short, jet-black hair is often tousled, reflecting his impatient nature. His eyes, a deep brown, carry a sharpness that hints at his intelligence and the manipulative charm he employs when necessary. Dressed in casual, comfortable clothes—often a simple t-shirt and jeans—he exudes a nonchalant air, but the tension in his jaw and the frequent pinching of the bridge of his nose betray his annoyance and impatience with the world.

Despite his aggressive tendencies when angered, Yoshirou is not easily provoked, a testament to his inner strength and control. His intelligence serves him well, making him a trustworthy confidant and a formidable opponent. Yet, there's a darker side to him; Yoshirou collects what he calls 'useless treasures'—small trinkets he steals, a habit that speaks to his rebellious nature and a longing for something more.

His family, particularly his mother, remains a pillar of support, embracing his identity with open arms. This unconditional love fuels Yoshirou's journey as a protagonist, pushing him to navigate the complexities of his life with courage. However, his path takes an unexpected turn when he finds himself transported to a strange fantasy world, a realm where his skills and flaws are put to the test.

In this new world, Yoshirou's quick forgiveness and slow forgetting become both a strength and a weakness. He is confronted with the realization that he might become the very thing he swore not to be, a struggle that defines his character arc and challenges him to redefine his sense of self.

At school, Yoshirou's friendships with Lucan and Emeria offer him glimpses of normalcy and connection. Lucan, with his undeniable attractiveness that draws the attention of many girls, contrasts with Yoshirou's more subdued presence. Emeria, a close friend, provides a deeper bond, understanding Yoshirou in ways others cannot.

Yoshirou's life is a constant battle between who he is and who he fears he might become, a journey marked by internal and external conflicts, yet driven by an unyielding desire to find his place in the world.
