ONA
Description
Junya Sasaki is one of the main characters from the franchise, a seventeen-year-old idol affiliated with D-Four Production. His birthday is August 17, making his zodiac sign Leo, and his blood type is O. He stands 173 centimeters tall and hails from Fukuoka. Junya has short blonde hair with several strands sticking up messily, and his distinctive purple eyes are often drawn as slightly slanted. He accessorizes with silver ear piercings and notably wears a yellow bracelet on his wrist, which he received as a souvenir from attending a live concert by his favorite senior idol unit, Sankishi. His casual style often incorporates elements of his preferred brand, Flow terrace.

Junya’s initial outward demeanor can come across as arrogant, cunning, and blunt. He is highly competitive and stubborn, which often puts him at odds with others, particularly his fellow idol Kanade Amamiya. However, this sharp exterior is not the full measure of his character. Beneath the surface, Junya possesses a strong sense of responsibility and a more supportive nature. When a colleague shows doubt or anxiety, he often finds subtle ways to boost their confidence rather than tear them down. On stage, his personality shifts notably; he becomes much brighter, more outgoing, and charismatic, captivating the audience with an energy that contrasts with his off-stage sharpness. He is also described as having a natural talent for engaging in witty conversation, which makes him a favorite during the talk segments of variety shows.

Junya’s motivation to become an idol began when his older sister dragged him to a concert during his childhood. It was there that he first saw Haruto Mikami, the leader of Sankishi, and developed a deep admiration for him. This admiration became the driving force behind his career choice, and he has idolized Haruto ever since, collecting every magazine the senior idol has appeared in and finding it difficult to refuse anything Haruto suggests. Unlike many of his peers who balance school with their careers, Junya chose to pursue idol work full-time immediately after graduating from middle school, opting not to attend high school. His family consists of his parents, an older sister, and a family dog named John, which anchors his pragmatic worldview.

Within the story, Junya serves as both a rival and a leader. He is initially described as someone who challenges the protagonist, telling Kanade he does not have what it takes to be an idol, which sparks the competitive fire that drives the early narrative. Junya was a member of a subunit called Traffic Signal alongside Kanade and Shin Oikawa, where he acted as the leader. Later, when the five main members are brought together to form the final group DearDream, Junya continues to hold the position of leader. His role is not just ceremonial; he devises rigorous training plans and fosters collaboration, proving that his strategic mind is as sharp as his stage presence.

The most significant relationship in Junya’s life is his dynamic with Kanade Amamiya. They share a great deal in common, particularly their stubbornness and competitive spirits, which leads them to argue frequently and frustrate each other. However, this rivalry deepens into a form of camaraderie and mutual respect. When Kanade is doubtful or worried, Junya is often the one who finds a way to reinforce his confidence, pushing him to embrace his authenticity. Another key relationship is with the iconic idol Haruto, whom Junya looks up to immensely. His character arc involves moving beyond simply wanting to emulate Haruto; he grows from just mirroring the techniques of his hero to carving out his own unique musical identity. This ambition eventually shifts from a desire for individual triumph to a commitment to collective success. In a significant moment of development, Junya rejects a solo training offer in New York to remain the leader of DearDream, cementing his loyalty to the group over personal glory.

In terms of notable abilities, Junya possesses several talents outside of singing and dancing. He is skilled at both cooking and sewing, which are listed as his special skills. He claims to be addicted to making curry from scratch using various spices, though ironically, he personally dislikes eating very spicy food and also has a distaste for natto. He also enjoys surfing as a hobby. These concrete skills, combined with his sharp wit and evolving leadership, make him a foundational pillar of his unit.
