Description
Hayato Akiyama is a seventeen-year-old idol affiliated with 315 Production, where he serves as the passionate leader and guitarist of the high school band unit High×Joker. His physical appearance includes moss green hair, brown-hazel eyes, and a below-average height of 162 centimeters, and he originally comes from Hyougo prefecture. Before entering the world of idols, Hayato’s former job was as the guitarist of his school’s light music club, an ensemble he took the initiative to form.

Personality-wise, Hayato is characterized by his energetic and friendly nature. He is a boy who gets excited easily but generally maintains a balanced approach without going too overboard. At his core, he is deeply passionate about music and performance, with a strong desire to become popular and to one day see a huge crowd listening to the songs he has composed on a grand stage. His motivation for starting his high school band was originally this wish to be popular, but over time his love for playing the guitar has grown to be just as important. Despite his strong ambition, Hayato is not self-centered; he never tries to overshadow his fellow band members and possesses a strong sense of responsibility as a leader, always ready to help his friends when they face trouble or difficulties during practice. One of his more endearing traits is that he is somewhat of a crybaby, frequently shedding tears when overwhelmed by happiness, which was notably demonstrated when High×Joker won first place in the 1st SideM Election.

Within the narrative of SideM, Hayato’s primary role is as the driving force and founder of High×Joker. The unit originally started with just three senior members himself, Jun Fuyumi, and Natsuki Sakaki before being joined by Haruna Wakazato and Shiki Iseya the following year. His creative role extends beyond performance, as he is also the unit’s composer, frequently collaborating with Jun Fuyumi, who acts as the lyricist for their songs. The unit was eventually scouted by 315 Production after they witnessed one of the band’s performances, leading to their debut as idols. In the context of the unit, each member’s name contains a kanji relating to the seasons, with Hayato’s representing autumn. Symbolically, he is also associated with the Ace of Hearts card motif.

Key relationships define much of his development. His bond with Jun Fuyumi is particularly notable, as their creative partnership in writing music and lyrics is central to High×Joker’s identity. As the founder, he shares a deep sense of camaraderie with all unit members Natsuki, Shiki, and Haruna, whom he views as friends he wants to protect and support. A significant milestone in Hayato’s development was the 1st SideM Election, where High×Joker, under his leadership, was ranked the most popular unit, a moment that brought him to tears of joy and validated his efforts to gain recognition. In terms of abilities, Hayato specializes in playing the electric guitar, which he considers the coolest instrument, and is a skilled composer. His hobbies include playing video games, and he possesses a unique practical skill in imitating baseball players.
