Description
Rika Hoshizaki attends high school in Class 1-D as a Leo born on August 1. She lives in a strict single-parent household with her father and younger sister Risa Hoshizaki. Her father emphasizes academic success, causing friction as Rika chooses an independent path. Secretly, she operates as the popular MeTube streamer "Mirika" or "Milika," gathering 50,000 subscribers after initial streaming failures led her to incorporate cleavage-focused content for viewer growth. This hidden career finances purchases like camping gear or an apartment but risks exposure to her family and school. Her father strongly condemns streaming and threatens to delete her channel if discovered.

Physically, Rika stands 163 cm tall with blonde hair styled in short twin tails and green eyes. She possesses visibly sharp canine teeth and a G-cup bust, which she accentuates during streams for viewership. Her standard school uniform includes an orange bowtie and black over-the-calf socks. Personality-wise, she exhibits arrogance through open boasting about her physique and achievements. She demonstrates extreme persistence in romantic pursuits alongside impulsivity and reckless actions without considering consequences. Despite this bold exterior, sincere praise or affection triggers vulnerability, often causing embarrassed reactions. She maintains strong intuitive skills for discerning hidden emotions in others but performs poorly academically.

Her fixation on Mukai Naoya began when wounded pride from his rejection of her proposal to become his third girlfriend alongside Saki Saki and Nagisa Minase fueled a determination to "win" him. This led to extreme behaviors: camping in his backyard, blocking his home entrance, administering sleeping pills to separate him from others, and near-sexual assault. Her motivations shifted to genuine romantic feelings after Naoya defended her streaming career to her father. She escalated her pursuit by stealing Naoya’s first kiss and publicly confessing. Later, she rented an apartment adjacent to his home, moving in with Risa to remain close. Naoya permitted a five-month challenge for her to earn his affection; her unwavering dedication resulted in becoming his fourth and final girlfriend.

Initially aiming to displace Saki and Nagisa to monopolize Naoya, Rika eventually accepted the polyamorous dynamic. She alternates between clashing and cooperating with rival Shino Kiryū, forming temporary alliances. Her bond with sister Risa remains supportive despite Risa’s disapproval of her extreme methods. Conflict persists with her father, who condemns her streaming career and whom she once listed among her most hated individuals. Her favorite food is hamburger steak, and she identifies lions as her favorite animal.
