Before rising to fame as the Cyber Chef, Eiji Ono honed his skills in a lab developing what he dubbed "Polyfunctional Assistance Cubes" – a high-tech invention intended to aid humans in their daily lives. However, as geopolitical tensions grew, Eiji had to abandon his facility and reluctantly bid farewell to his promising PAC designs – which then almost sank into oblivion. Luckily, local technicians found Eiji’s notes and finally managed to activate the complex production mechanism – but only for a brief time window, as the condition of the machines started deteriorating quickly. That’s why today the engineers have invited all parties interested in acquiring a PAC to join them for this time-limited opportunity.
