Description
Hiyori Tomoe is a third-year student at Reimei Academy and a member of the idol units Eden and Eve at COSMIC PRODUCTION, leading Eve alongside Jun Sazanami. Born into the noble Tomoe Foundation, he views others as socially inferior yet displays a complex character. Outwardly bright, cheerful, and sociable, he radiates blinding energy and craves attention. Described as flippant and selfish, he often disregards others' viewpoints but paradoxically forms intense attachments. He habitually assists those he deems unfortunate, like rescuing Jun from a "garbage dump" situation or adopting an abandoned dog. Hiyori willingly adjusts his schedule to help those in genuine need, revealing a nurturing instinct.

Significant internal conflict stems from his background. As the Tomoe family's second son, he adopted a "foolish and playful" persona to avoid overshadowing his older brother, the heir. This act resulted in a loss of self-identity, leaving him feeling hollow after "cutting away and burning his heart as fuel to sparkle." He remains deeply devoted to his family, striving to enhance their reputation through his idol work and fearing failure might burden them. The Tomoe Foundation, once a zaibatsu, declined after World War II but retains wealth and a rivalry with the Tenshouin family.

Hiyori avoids discussing painful pasts, particularly concerning his family or time in the disbanded unit fine, though he still considers its members dear friends. A dread of being disliked drives his idol goal to "spread smiles and love worldwide" and achieve universal adoration. His performances exhibit elegance and clear vocals, captivating audiences like the sun drawing others into its orbit—a metaphor linked to his name's meaning ("weather" or "day"). He engages in wordplay using this, referencing "ii hiyori" (good weather/good day) and "warui hiyori" (bad weather/bad day).

Physically tall at 177 cm with a slightly chubby build, he has light yellow-green wavy hair, violet eyes, and effeminate eyelashes. His fashion evolves seasonally, favoring refined styles like vests, turtlenecks, and statement accessories such as watches and a gold necklace. He is weak to cold weather and dislikes insects, fish, exercise, and sweat smells, claiming idol practice suffices for fitness.

His relationships reveal further layers. He mentors Jun and harbors protectiveness toward Nagisa Ran due to their childhood bond, resenting Ibara Saegusa for negatively influencing Nagisa. Hiyori rescued a blood-covered abandoned dog with Jun, naming her Bloody Mary. He secretly kept her in his school dorm despite rules, later moving her to his Ensemble Square dorm. He frequently floods Eden’s group chats with her photos. He values fan interactions, embracing trends and treasuring fan letters.

Additional traits include conversational English skills, a love for merchandise and shopping, a preference for new over old things, favorite foods like salmon quiche, and talents in memory and flower arrangement. Spontaneous whims often disrupt schedules, causing lateness or protests, yet he possesses perceptiveness and teaching ability, traits noted even in childhood with Nagisa.
