Hikari Jinguuji, a film club alumna, maintains ties to the Narukami family through her friendship with Sora Narukami, a current club member. She labors at her family’s ramen shop, Ramen Heavenward, which teeters on collapse under suffocating debt from high-interest loans acquired by her mother. When her mother falls critically ill, Hikari shoulders the business alone, juggling daily operations while evading relentless debt collectors.

A confrontation with a collector spirals into chaos when Sora intervenes to protect her, sustaining injuries that compel Hina and Youta Narukami to act. Youta orchestrates a turnaround, masquerading as a consultant to rebrand the restaurant as “Fallen Angel.” He streamlines the menu, launches targeted social media campaigns, and introduces eye-catching themed events, gradually reviving its fortunes. The resurgence stabilizes finances, easing the collectors’ threats.

Hikari’s pragmatism and quiet determination emerge through her collaboration with Youta and Hina, showcasing her adaptability amid crisis. Her story intertwines familial duty with fragile hope, anchoring her relationships in shared hardship. While her actions drive collective solutions during the restaurant’s revival, her personal ambitions and connections beyond this struggle remain undefined within the existing narrative framework.
