What Flaggs does

Flaggs Inc. (株式会社flaggs) is a Tokyo-based smartphone game developer founded on March 20, 2015, that specializes in character-driven mobile entertainment apps for the otome/romance-simulation and VTuber-fan categories. The company's flagship current product is 'Obey Me! Till Death Do Us Part' (おべてぃる), a marriage-themed lifestyle support app released globally on iOS and Android on December 12, 2025, which was co-developed with NTT Solmare (the original publisher of the 'Obey Me!' franchise, which has accumulated 11M+ downloads since 2019) and CREEK & RIVER's C&R Creative Studios. A prior title, 'Stpr With!!' (2024), was built around entertainment unit Stpr and has since been transferred to another operator; earlier titles (fingger, HoneyWorks Premium Live, 彗星のアルナディア) are listed as service-ended on the corporate site.

Technology centers on Live2D animation for expressive character rendering, combined with custom gameplay systems — gacha draws, character and room customization, and embedded lifestyle features such as chat, weather forecasts, and calendar integration. The company monetizes via a freemium model: games are free to download globally through the App Store and Google Play, with revenue generated from in-app purchases of costumes, gacha draws, digital goods, and decoration items. Distribution and discovery are supported by official X/Instagram accounts, pre-registration campaigns, and crowdfunding on Kickstarter and Cereus. In June 2025 Flaggs transferred its animation production business to Hellarts Inc. and repositioned around game development and new services, while CEO Naoto Yoshie (吉江直人) leads the company and Cygames is listed as a related/affiliated company on the corporate website.

Direct peers

• KLab Inc. Tokyo-listed mobile game developer known for rhythm and IP-licensed games (e.g., Love Live! School Idol Festival, Bleach). Comparable to Flaggs as a Japanese mobile game studio leveraging popular IP licenses and gacha-based monetization on smartphone platforms.
• Voltage Inc. Japan/US-based mobile game publisher specializing in otome and romance simulation apps for women. Directly comparable to Flaggs as it competes in the same otome/lifestyle mobile game category with a similar character-driven, gacha-supported monetization approach.
• Happy Elements: Kyoto-based mobile game developer best known for the 'Ensemble Stars!' otome/idol franchise. Directly comparable to Flaggs given its focus on character-rich otome mobile games with Live2D animation, gacha monetization, and dedicated female fanbase.
• Idea Factory / Otomate: Japanese game developer and its Otomate brand specialize in otome visual novels and romance games across mobile and console. Comparable to Flaggs as it operates in the otome genre with similar character IP focus, though with stronger console/visual novel roots.

Broad incumbents

• Cygames: One of Japan's largest mobile game developers (Granblue Fantasy, Uma Musume, Princess Connect), listed as a related/affiliated company on Flaggs' corporate site. Comparable as a Japanese mobile game powerhouse operating in the same broader gacha/character-driven category, though at vastly larger scale and with owned IP.
• mixi Inc. Tokyo-listed mobile and social gaming company best known for 'Monster Strike'. Comparable as a broader incumbent in the Japanese mobile gaming space, though operating at much larger scale and with different genre focus.
• CyberAgent, Inc. Tokyo-listed internet media conglomerate and parent company of Cygames (Flaggs' related company). Comparable as the broader corporate ecosystem that Flaggs sits adjacent to, providing a relevant reference for capital, scale, and exit dynamics in the Japanese mobile gaming industry.
• COLOPL, Inc. Tokyo-listed mobile game developer/publisher with a portfolio of casual and location-based games. Comparable as a Japanese mobile game developer competing for similar smartphone-gamer mindshare, though more focused on casual/hyper-casual than otome.

Others

• STPR Corporation: Japanese VTuber/entertainment agency that produces the 'Stpr' entertainment unit for which Flaggs developed 'Stpr With!!'. Comparable as the IP owner/strategic partner providing the entertainment property that Flaggs' game was built around, illustrating the agency's pivotal role in Flaggs' IP-partnership model.
• NTT Solmare Corporation: Japanese digital content publisher operating major ebook platforms (e.g., 'Comic Cmoa') and the original publisher of the 'Obey Me!' franchise. Comparable as Flaggs' flagship co-development partner — they jointly publish and develop 'Obey Me! Till Death Do Us Part', making them a strategic counterpart rather than a direct competitor.
