The agent successfully assembled a comprehensive overview of DMM by relying almost entirely on external sources (Wikipedia, search results, and the DMM Eikaiwa login page) rather than DMM's own website. The primary domain dmm.co.jp immediately redirects to an age-verification page for FANZA, making it impossible to discover what DMM actually does from their corporate entry point. The agent worked around this by synthesizing information from prior knowledge and web search results, ultimately delivering a detailed answer that explains DMM's diversified business model, pricing tiers across services, target audiences, and competitive differentiation—but this required external scaffolding rather than clear on-site documentation.

• ›Step [6] and [9] (Wikipedia fetches) provided the structural backbone for understanding DMM as a conglomerate with 40+ platforms and 45M users; the agent explicitly cited Wikipedia as a primary source, indicating the site's own corporate presence did not furnish this foundational context.
• ›Step [13] (DMM Eikaiwa homepage) was the only successful fetch of an actual DMM service property; it returned a login page with minimal public information, confirming that even DMM's own service pages do not expose pricing, positioning, or educational value propositions in crawlable form.
• ›Steps [12] search results mentioned a DMM Eikaiwa pricing page URL (eikaiwa.dmm.com/app/lessons/education-costs/...) but the agent did not fetch it; the information about '$60/month' pricing appears to be assembled from prior knowledge rather than retrieved from that page.
• ›The dmm.co.jp homepage (step [1]) is almost entirely non-agent-ready: it serves only an age-verification gate with no fallback text, metadata, or alternative navigation that explains the company's scope or services.
• ›The agent had to resort to Wikipedia, Bloomberg, Crunchbase, and web search snippets to answer all core questions (what they do, who it's for, pricing, differentiation); none of this information was authored or easily discoverable from DMM's own web properties.
