## Background of the Service Launch
Driven by recent inflation and the Nikkei Stock Average reaching new highs, interest in investing has grown, broadening the base of investors. This situation presents an excellent opportunity for many companies to widely publicize their appeal and acquire new shareholders. However, many IR representatives face challenges in finding effective means of information dissemination that appeal to retail investors, often dealing with limited opportunities for effective communication or biased, unobjective messaging.

Therefore, by providing this video production and distribution service for companies, the Company enables businesses to disseminate information from the perspective of retail investors. Simultaneously, it provides valuable information to retail investors, creating opportunities for mutually beneficial information exchange.
