In Kabukichou, a highly addictive love drug called "Burst" is rampant—it can artificially trigger an Omega's heat in its users. Kyouji, an elite Alpha detective leading the investigation, pays a large sum to a local influencer to chase down a lead. The person who shows up is Taiga — online streamer, former number-one host, and fellow Alpha.
Kyouji had once sheltered a young Taiga and let him live with him. However, for reasons unknown, they had been out of contact for many years.
"I need you to work as my informant and help me investigate Burst."

Taiga agrees without hesitation. Relieved, Kyouji accepts the coffee Taiga offers and takes a sip — only to be hit by an intense Omega heat!?

Can Kyouji endure the relentless heat — and still catch the culprit!?
