Haruhiko Beppu, a second-year Binan High student, thrives as the fiery half of the idol duo VEPPer alongside his twin Akihiko. Born under Leo’s sign on August 21, his ice-blue hair sweeps sharply to the right, framing crimson eyes and thicker brows than his brother. He towers slightly over Akihiko, clad in a minimalist uniform accented by a golden bow with a star-shaped ring. As Salty Sol, his sun-themed transformation wields massive star-scissors inspired by his bonsai hobby, contrasting Akihiko’s moon motif.

Haruhiko’s tongue cuts as keenly as his blades, spitting insults like “Trash” or “Lame” with rowdy passion. Yet beneath this abrasive shell lies unexpected tenderness: he attentively listens to others’ woes and nurtures bonsai to soothe his storms. His hobbies—horseback riding, gardening—reveal a duality mirrored in his tastes, favoring rice balls while scornfully rejecting carrots.

A childhood scarred by alien conflict defines him. Rescued by Gōra Hakone, only to face exile from the Andromeda Galaxy for idolizing the falsely vilified hero, Haruhiko spiraled into despair. Manipulated by the alien Dadacha, he and Akihiko embraced idolhood to lure Gōra’s attention, birthing Loveless monsters to challenge the Earth Defense Club—a twisted take on Gōra’s advice to “make mischief” and grow stronger.

His bond with Akihiko pulses with symbiosis: physically inseparable, yet emotionally distinct. Where Akihiko masks his edges, Haruhiko openly seethes at the Earth Defense Club, especially Yumoto Hakone, championing brute strength. Both twins orbit Gōra with near-obsessive fervor, tracking his movements until acknowledgment softens their fixation. Post-reconciliation, they pivot from antagonists to complex allies, respecting Battle Lovers and fans while retaining their idol identities. Their journey—from stalking shadows to accepted luminaries—echoes themes of loneliness and the perilous allure of hero worship, healed by purpose and belonging.
